A British colony in the Atlantic Islands, comprising two principal islands, East Falkland and West Falkland. Its capital is Stanley. Discovered in 1592, it was not occupied until the French settled there briefly in 1764. Later the English settled there but were expelled by the Spanish in 1770. The Falklands were claimed by Argentina but were occupied in 1833 by the British who, after an April 1982 invasion by Argentina, regained them in June. The islands were named by British Captain John Strong in 1690 for the fifth Viscount Falkland who financed Strong's expedition. The Spanish name for the islands, Malvinas, is from the French Malouins, inhabitants of St. Malo who attempted to colonize the islands in 1764.

Uncoupling protein and ATP/ADP carrier increase mitochondrial proton conductance after cold adaptation of king penguins. (1/135)

Juvenile king penguins develop adaptive thermogenesis after repeated immersion in cold water. However, the mechanisms of such metabolic adaptation in birds are unknown, as they lack brown adipose tissue and uncoupling protein-1 (UCP1), which mediate adaptive non-shivering thermogenesis in mammals. We used three different groups of juvenile king penguins to investigate the mitochondrial basis of avian adaptive thermogenesis in vitro. Skeletal muscle mitochondria isolated from penguins that had never been immersed in cold water showed no superoxide-stimulated proton conductance, indicating no functional avian UCP. Skeletal muscle mitochondria from penguins that had been either experimentally immersed or naturally adapted to cold water did possess functional avian UCP, demonstrated by a superoxide-stimulated, GDP-inhibitable proton conductance across their inner membrane. This was associated with a markedly greater abundance of avian UCP mRNA. In the presence (but not the absence) of fatty acids, these mitochondria also showed a greater adenine nucleotide translocase-catalysed proton conductance than those from never-immersed penguins. This was due to an increase in the amount of adenine nucleotide translocase. Therefore, adaptive thermogenesis in juvenile king penguins is linked to two separate mechanisms of uncoupling of oxidative phosphorylation in skeletal muscle mitochondria: increased proton transport activity of avian UCP (dependent on superoxide and inhibited by GDP) and increased proton transport activity of the adenine nucleotide translocase (dependent on fatty acids and inhibited by carboxyatractylate).  (+info)

Antennae on transmitters on penguins: balancing energy budgets on the high wire. (2/135)

The effect of externally mounted antennae on the energetics of penguins was studied by mounting various antennae on a transducer fixed to a model Magellanic penguin Spheniscus magellanicus to determine drag, run at speeds of up to 2 m s(-1) in a swim canal. For rigid antennae set perpendicular to the water flow, measured drag increased with increasing swim speed. Increasing antenna length (for lengths between 100 and 200 mm) or diameter (for diameters between 1 and 4 mm) resulted in accelerating increased drag as a function of both antenna length and diameter. Where antennae were positioned at acute angles to the water flow, drag was markedly reduced, as was drag at higher speeds in flexible antennae. These results were incorporated in a model on the foraging energetics of free-living Magellanic penguins using data (on swim speeds, intervals between prey encounters, amount ingested per patch and dive durations) derived from previously published work and from a field study conducted on birds from a colony at Punta Norte, Argentina, using data loggers. The field work indicated that free-living birds have a foraging efficiency (net energy gain/net energy loss) of about 2.5. The model predicted that birds equipped with the largest rigid external antennae tested (200 mm x 3 mm diameter), set perpendicular to water flow, increased energy expenditure at normal swim speeds of 1.77 m s(-1) by 79% and at prey capture speeds of 2.25 m s(-1) by 147%, and ultimately led to a foraging efficiency that was about 5 times less than that of unequipped birds. Highly flexible antennae were shown to reduce this effect considerably. Deleterious antenna-induced effects are predicted to be particularly critical in penguins that have to travel fast to capture prey. Possible measures taken by the birds to increase foraging efficiency could include reduced travelling speed and selection of smaller prey types. Suggestions are made as to how antenna-induced drag might be minimized for future studies on marine diving animals.  (+info)

Adjustments of gastric pH, motility and temperature during long-term preservation of stomach contents in free-ranging incubating king penguins. (3/135)

Male king penguins are able to store undigested food in their stomach for up to 3 weeks during their incubation fast, which evidently implies some modification of their digestive process. Using small electronic recorders, we studied the change in gastric pH, motility and temperature during the first week of food storage. The pH could be maintained at values as high as 6 throughout the incubation fast, a pH that is unfavourable for avian gastric proteinase activity. Gastric motility was never completely inhibited but could be markedly reduced. Stomach temperature was maintained at around 38 degrees C. The fact that stomach temperature of incubating birds did not show a daily rhythmic fluctuation as seen in non-breeding birds could be due to temperature constraints on embryo development. Thus the present study demonstrates substantial adjustments of pH and gastric motility in incubating king penguins, which may contribute to the inhibition of digestive gastric processes.  (+info)

Penguins and their noisy world. (4/135)

Penguins identify their mate or chick by an acoustic signal, the display call. This identification is realized in a particularly constraining environment: the noisy world of a colony of thousands of birds. To fully understand how birds solve this problem of communication, we have done observations, acoustic analysis, propagation and playback experiments with 6 species of penguins studied in the field. According to our results, it appears that penguins use a particularly efficient "anti-confusion" and "anti-noise" coding system, allowing a quick identification and localization of individuals on the move in a noisy crowd.  (+info)

Heart rate and energetics of free-ranging king penguins (Aptenodytes patagonicus). (5/135)

The main objective of this study was to determine heart rate (fh) and the energetic costs of specific behaviours of king penguins while ashore and while foraging at sea during their breeding period. In particular, an estimate was made of the energetic cost of diving in order to determine the proportion of dives that may exceed the calculated aerobic dive limit (cADL; estimated usable O2 stores/estimated rate of oxygen consumption during diving). An implanted data logger enabled fh and diving behaviour to be monitored from 10 free-ranging king penguins during their breeding period. Using previously determined calibration equations, it was possible to estimate rate of oxygen consumption (VO2) when the birds were ashore and during various phases of their foraging trips. Diving behaviour showed a clear diurnal pattern, with a mixture of deep (>40 m), long (>3 min) and shallow (<40 m), short (<3 min) dives from dawn to dusk and shallow, short dives at night. Heart rate during dive bouts and dive cycles (dive + post-dive interval) was 42% greater than that when the birds were ashore. During diving, fh was similar to the 'ashore' value (87+/-4 beats min(-1)), but it did decline to 76% of the value recorded from king penguins resting in water. During the first hour after a diving bout, fh was significantly higher than the average value during diving (101+/-4 beats min(-1)) and for the remainder of the dive bout. Rates of oxygen consumption estimated from these (and other) values of fh indicate that when at sea, metabolic rate (MR) was 83% greater than that when the birds were ashore [3.15 W kg(-1) (-0.71, +0.93), where the values in parentheses are the computed standard errors of the estimate], while during diving bouts and dive cycles, it was 73% greater than the 'ashore' value. Although estimated MR during the total period between dive bouts was not significantly different from that during dive bouts [5.44 W kg(-1) (-0.30, +0.32)], MR during the first hour following a dive bout was 52% greater than that during a diving bout. It is suggested that this large increase following diving (foraging) activity is, at least in part, the result of rewarming the body, which occurs at the end of a diving bout. From the measured behaviour and estimated values of VO2, it was evident that approximately 35% of the dives were in excess of the cADL. Even if VO2 during diving was assumed to be the same as when the birds were resting on water, approximately 20% of dives would exceed the cADL. As VO2 during diving is, in fact, that estimated for a complete dive cycle, it is quite feasible that VO2 during diving itself is less than that measured for birds resting in water. It is suggested that the regional hypothermia that has been recorded in this species during diving bouts may be at least a contributing factor to such hypometabolism.  (+info)

Why do macaroni penguins choose shallow body angles that result in longer descent and ascent durations? (6/135)

It is generally assumed that air-breathing aquatic animals always choose the shortest route to minimize duration for transit between the surface and foraging depth in order to maximize the proportion of time spent foraging. However, empirical data indicate that the body angles of some diving animals are rarely vertical during descent and ascent. Why do they choose shallower body angles that result in longer descent and ascent durations? To investigate this question, we attached acceleration data loggers to eight female macaroni penguins, breeding on the Kerguelen Islands (48 degrees 45'-50 degrees 00' S, 68 degrees 45'-70 degrees 58' E; South Indian Ocean), to record depth, two-dimensional acceleration (stroke cycle frequency and body angle) and temperature. We investigated how they controlled body angle and allocated their submerged time. The instrumented females performed multiple dives (N=6952) with a mean dive depth for each bird ranging from 24.5+/-28.5 m to 56.4+/-75.1 m. Mean body angles during descent and ascent were not vertical. There was large variation in mean descent and ascent angles for a given dive depth, which, in turn, caused large variation in descent and ascent duration. Body angles were significantly correlated with time spent at the bottom-phase of the dive. Birds that spent long periods at the bottom exhibited steep body angles during ascent and subsequent descent. By contrast, they adopted shallow body angles after they had short or no bottom phases. Our results suggest that macaroni penguins stay at the bottom longer after encountering a good prey patch and then travel to the surface at steep body angles. If they do not encounter prey, they discontinue the dive, without staying at the bottom, ascend at shallow body angles and descend at shallow body angles in a subsequent dive. A shallow body angle can increase the horizontal distance covered during a dive, contributing to the move into a more profitable area in the following dive. During the ascent, in particular, macaroni penguins stopped beating their flippers. The buoyantly gliding penguins can move horizontally with minimum stroking effort before reaching the surface.  (+info)

Penguin-mounted cameras glimpse underwater group behaviour. (7/135)

Marine birds and mammals spend most of their lives in the open ocean far from human observation, which makes obtaining information about their foraging behaviour difficult. Here, we show, by use of a miniaturized digital camera system, the first direct evidence (to our knowledge) of underwater group behaviour in free-ranging penguins. Penguins swim closely accompanied by other bird(s) during 24% of their possible foraging dives. This finding confirms that such miniaturized camera technology has broad applicability for advancing our knowledge about the previously unknown social interactions of marine animals at depth.  (+info)

Long-term effects of flipper bands on penguins. (8/135)

Changes in seabird populations, and particularly of penguins, offer a unique opportunity for investigating the impact of fisheries and climatic variations on marine resources. Such investigations often require large-scale banding to identify individual birds, but the significance of the data relies on the assumption that no bias is introduced in this type of long-term monitoring. After 5 years of using an automated system of identification of king penguins implanted with electronic tags (100 adult king penguins were implanted with a transponder tag, 50 of which were also flipper banded), we can report that banding results in later arrival at the colony for courtship in some years, lower breeding probability and lower chick production. We also found that the survival rate of unbanded, electronically tagged king penguin chicks after 2-3 years is approximately twice as large as that reported in the literature for banded chicks.  (+info)

Aptenodytes patagonicus is closely related to Aptenodytes forsteri, emperor penguins. Adult king penguins are smaller than emperor penguins, measuring between 85 and 95 cm tall. Males are generally taller than females, otherwise they are monomorphic. They weight from 11 to 15 kg. King penguins have a rounded body, silvery-grey back, and a dark (blackish-brown) head. They are known for their bright-orange ear patch and for the bright-pink patch on the mandible, which is larger than that of emperor penguins. They use their white and black flippers, or wings, for swimming and their black feet for walking on land, as they cannot fly. Aptenodytes patagonicus is more slender in the body and has a longer bill than emperor penguins. Their dense plumage protects them from bitter, sub-Antarctic weather and consists of four layers: the outer layer is oily and waterproof and encloses three downy layers for insulation.

The king penguin stands at 70 to 100 cm (28 to 39 in) tall and weighs from 9.3 to 18 kg (21 to 40 lb).[4][5][6] Although female and male king penguins are monomorphic they can be separated by their calls.[7] Males are also slightly larger than females. The mean body mass of adults from Marion Island was 12.4 kg (27 lb) for 70 males and 11.1 kg (24 lb) for 71 females. Another study from Marion Island found that the mean mass of 33 adults feeding chicks was 13.1 kg (29 lb). The king penguin is approximately 25% shorter and weighs around 1/3rd less than the emperor penguin.[8][9]. At first glance, the king penguin appears very similar to the larger, closely related emperor penguin, with a broad cheek patch contrasting with surrounding dark feathers and yellow-orange plumage at the top of the chest. However, the cheek patch of the adult king penguin is a solid bright orange whereas that of the emperor penguin is yellow and white, and the upper chest tends to be more orange and less yellowish in the ...

Our aim was to estimate the population of emperor penguins (Aptenodytes fosteri) using a single synoptic survey. We examined the whole continental coastline of Antarctica using a combination of medium resolution and Very High Resolution (VHR) satellite imagery to identify emperor penguin colony locations. Where colonies were identified, VHR imagery was obtained in the 2009 breeding season. The remotely-sensed images were then analysed using a supervised classification method to separate penguins from snow, shadow and guano. Actual counts of penguins from eleven ground truthing sites were used to convert these classified areas into numbers of penguins using a robust regression algorithm. We found four new colonies and confirmed the location of three previously suspected sites giving a total number of emperor penguin breeding colonies of 46. We estimated the breeding population of emperor penguins at each colony during 2009 and provide a population estimate of ∼238,000 breeding pairs (compared with the

Penguins are vulnerable to interference by humans, especially while they are ashore during moult or nesting periods. In 1930 in Tasmania, it was believed that little penguins were competing with mutton-birds, which were being commercially exploited. An open season in which penguins would be permitted to be killed was planned in response to requests from members of the mutton-birding industry.[117] In the 1930s, an arsonist was believed to have started a fire on Rabbit Island near Albany, Western Australia- a known little penguin rookery. Visitors later reported finding dead penguins there with their feet burned off.[118] In 1938 an account was given of a little penguin found with its flippers tied together with fishing line.[119] In 1949, penguins on Phillip Island in Victoria became victims of human cruelty, with some kicked and others thrown off a cliff and shot at. These acts of cruelty prompted the state government to fence off the rookeries.[120] In 1973, ten dead penguins and fifteen ...

Penguins are classified in the order Sphenisciformes into a single family, Spheniscidae. The genus Pygoscelis Wagler, 1832, is composed of three species, Pygoscelis antarcticus Forster, 1781, P. papua Forster, 1781 and P. adeliae Hombron & Jacquinot, 1841. In this work, the objective was to describe and to compare the karyotypes of Pygoscelis penguins contributing genetic information to Sphenisciformes. The metaphases were obtained by lymphocyte culture, and the diploid number and the C-banding pattern were determined. P. antarcticus has 2n = 92, P. papua 2n = 94 and P. adeliae exhibited 2n = 96 in males and 2n = 95 in females. The difference of diploid number in P. adeliae was identified as a multiple sex chromosome system where males have Z1Z1Z2Z2 and females Z1Z2W. The C-banding showed the presence of a heterochromatic block in the long arm of W chromosome and Z2 was almost entirely heterochromatic. The probable origin of a multiple system in P. adeliae was a translocation involving the W
Adult emperor penguins stand up to 110-130 cm (43-51 in) tall.[8] The weight ranges from 22.7 to 45.4 kg (50 to 100 lb) and varies by sex, with males weighing more than females. It is the fifth heaviest living bird species, after only the larger varieties of ratite.[9] The weight also varies by season, as both male and female penguins lose substantial mass while raising hatchlings and incubating their egg. A male emperor penguin must withstand the Antarctic cold for more than two months to protect his egg from extreme cold. During this entire time he does not eat anything. Most male penguins will lose about 12 kg (26 lb) while they wait for their chicks to hatch.[10] The mean weight of males at the start of the breeding season is 38 kg (84 lb) and that of females is 29.5 kg (65 lb). After the breeding season this drops to 23 kg (51 lb) for both sexes.[11][12][13]. Like all penguin species, emperor penguins have streamlined bodies to minimize drag while swimming, and wings that are more like ...

The anatomy and volume of the penguin respiratory system contribute significantly to pulmonary baroprotection, the body O-2 store, buoyancy and hence the overall diving physiology of penguins. Therefore, three-dimensional reconstructions from computerized tomographic (CT) scans of live penguins were utilized to measure lung volumes, air sac volumes, tracheobronchial volumes and total body volumes at different inflation pressures in three species with different dive capacities [Adelie (Pygoscelis adeliae), king (Aptenodytes patagonicus) and emperor (A. forsteri) penguins]. Lung volumes scaled to body mass according to published avian allometrics. Air sac volumes at 30 cm H2O (2.94 kPa) inflation pressure, the assumed maximum volume possible prior to deep dives, were two to three times allometric air sac predictions and also two to three times previously determined end-of-dive total air volumes. Although it is unknown whether penguins inhale to such high volumes prior to dives, these values were ...
How genetic diversity is maintained in philopatric colonial systems remains unclear, and understanding the dynamic balance of philopatry and dispersal at all spatial scales is essential to the study of the evolution of coloniality. In the King penguin, Aptenodytes patagonicus, return rates of post-fledging chicks to their natal sub-colony are remarkably high. Empirical studies have shown that adults return year after year to their previous breeding territories within a radius of a few meters. Yet, little reliable data are available on intra- and inter-colonial dispersal in this species. Here, we present the first fine-scale study of the genetic structure in a king penguin colony in the Crozet Archipelago. Samples were collected from individual chicks and analysed at 8 microsatellite loci. Precise geolocation data of hatching sites and selective pressures associated with habitat features were recorded for all sampling locations. We found that despite strong natal and breeding site fidelity, king ...

N2 - We present a novel pair of numerical models of the interaction history between the Large and Small Magellanic Clouds (LMC and SMC, respectively) and our Milky Way (MW) in light of recent high-precision proper motions from the Hubble Space Telescope. Given the updated velocities, cosmological simulations of hierarchical structure formation favour a scenario where the Magellanic Clouds (MCs) are currently on their first infall towards our Galaxy. We illustrate here that the observed irregular morphology and internal kinematics of the Magellanic System (in gas and stars) are naturally explained by interactions between the LMC and SMC, rather than gravitational interactions with the MW. These conclusions ...
380) Penguin. Penguin, (order Sphenisciformes), any of 18 species of flightless marine birds that live only in the Southern Hemisphere. The majority of the 18 species live not in Antarctica but rather between latitudes 45° and 60° S, where they breed on islands. A few penguins inhabit temperate regions, and one, the Galapagos penguin (Spheniscus mendiculus), lives at the Equator.. General Features. The stocky, short-legged appearance of penguins has endeared them to people worldwide. They range from about 35 cm (14 inches) in height and approximately 1 kg (about 2 pounds) in weight in the blue, or fairy, penguin(Eudyptula minor) to 115 cm (45 inches) and 25 to 40 kg (55 to 90 pounds) in the emperor penguin (Aptenodytes forsteri). Most are black on the back and white below, often with lines of black across the upper breast or spots of white on the head. Colour is rare, being limited to red or yellow irises of the eye in some species; red beaks or feet in a few; yellow brow tufts in the three ...

Comedy Central Jokes - Tom Rhodes: Penguins Are Better Than You - A penguin has the same little penguin for a total little penguin life. Think how many screwed up relationships you
Egg-laying takes place in spring and summer, and the chicks are kept in the colony until the following spring. An abundance of plankton in spring means a good supply of food for the penguins. They catch fish and cephalopods in surface waters and can, therefore, fee their young abundantly.. Each parent tends a single egg which is incubated beneath the abdominal fold of skin and balanced on the feet so as to protect it from the ground below. When exchanging the egg, the parents perform the maneuver with such dexterity that it never comes into contact with soil or snow.. Nevertheless, not all the chicks manage to survive the rigors of the southern winter and the inevitable scarcity of food in the nesting colonies. Adults are subject to molting. Couples can raise two chicks in three consecutive years.. Like the Emperor penguin, the King penguin has difficulties in raising its larger chicks because of the harsh conditions in which these already-large animals live. The severe climate means food is ...

Although much of Pew’s global penguin conservation work has focused on protecting the world-famous penguins of Antarctica, the majority of penguin species don’t live on the frozen continent. In fact, only 6 of 18 species live there, which means that many other populations of the Southern Hemisphere’s penguins are in need of conservation efforts, too. These include the endangered yellow-eyed penguin of New Zealand, which has plummeted in population size because of habitat degradation and invasive species, and now consists of only about 1,700 breeding pairs. Yellow-eyed penguins live on New Zealand’s South Island and Stewart Island and the adjacent Auckland and Campbell islands. Unlike other penguin species, they do not nest close to one another. Instead, they build nests in dense forests and leave a good amount of space between themselves and their closest neighbor. Unfortunately, much of their forest habitat was cleared for pastures for sheep and cattle during the 20th century,

Venture to a far-flung corner of the Earth to get an intimate look at the spectacular world of king penguins and elephant seals inhabiting the island of South Georgia.
Australian scientists have shown for the first time that penguins living on a remote sub-Antarctic island are infected with viruses whose closest relatives are in the Northern Hemisphere.. Virologists from the Queensland Institute of Medical Research (QIMR), made the discovery while studying penguin colonies on Macquarie Island. The island, which is located between Australia and Antarctica, is home to rockhopper, royal and king penguins, which are often teeming with the globally distributed virus-transmitting seabird tick, Ixodes uriae.. The penguins were infected with a surprising number and diversity of viruses, known as arboviruses, according to team leader and QIMR Immunovirology Laboratory Head, Professor Andreas Suhrbier.. Ticks carried by several migrating seabird species which visit Macquarie Island and all other continents of the world, are probably responsible for regular transport of seabird viruses around the world, said Professor Suhrbier.. We wanted to analyse these viruses ...
Paleontologists at the University of Texas at Austin and other institutions have investigated the fossil of a giant penguin found in Peru. At five feet tall, it would have dwarfed todays largest living penguins. A UT press release stated, The fossil shows [that] the flipper and feather shapes that make penguins such powerful swimmers evolved early.1. The sudden appearance of penguins has been an evolutionary mystery. Their fossils are rare, prompting at least one evolutionist to speculate on penguin origins based on the kinds of fleas they have in common with rodents! Writing in Vertebrate History: Problems in Evolution, technical author Barbara Stahl stated, Since no site has yet given up a specimen recognizable as protopenguin, it is impossible to guess where or even in which climate penguin history began.2. The Peruvian penguin, named Inkayacu paracasensis, is not a protopenguin either. Instead, it has all of the standard penguin features, including a torpedo-shaped body, solid bones to ...
The Ross Sea contains more than a quarter of the worlds emperor penguins, more than a third of its Adélie penguins, and species of fish and invertebrates found nowhere else on Earth.
Ewan Fordyce, a palaeontologist at the island nations University of Otago, found the ancient bones to make nearly an entire skeleton 35 years ago - and in the last few years enlisted the help of two more boffins from North Carolina State University to figure out what the huge penguin would have looked like.. New Zealand was a great place for penguins around 25 million years ago, during the Oligocene period, because most of the country was underwater leaving rocky islands scattered about where penguins could hide out from predators and forage for food.. The giant penguin, which the boffins named Kairuku after the Maori for diver who returns with food, was one of at least five different species of penguin that lived in New Zealand at this time. The diversity of species is one of the reasons that figuring out what Kairuku looked like was difficult as well as its unique appearance.. Kairuku was more than a foot taller than the modern Emperor penguin and had a long narrow bill and narrow wing ...

Anaplasma spp. are Gram-negative obligate intracellular bacteria transmitted by ticks. Even though numerous studies have detected DNA from Anaplasma spp. in the blood of birds, thus far mammals were the only vertebrates demonstrated to serve as competent hosts to these organisms. We report a novel candidate species of Anasplasma that was associated with cytoplasmic inclusions in the erythrocytes of an African penguin (Spheniscus demersus) in South Africa. Cytoplasmic inclusions were morphologically characterized from freshly-produced blood smears, and phylogenetic analysis of 16S rRNA and groEL genes were used to evaluate the evolutionary relationships of the organism to other Anaplasmataceae. Dark-purple round or oval inclusions consistent with Anaplasmataceae morulae were observed in the cytoplasm of erythrocytes. Phylogenetic trees produced using different methods agreed that the organism detected in this study belongs to the genus Anaplasma, and suggested that it is most closely related to the

Eudyptes chrysolophus breeds in at least 258 colonies at c. 55 breeding sites (Crossin et al. 2013), including southern Chile, the Falkland Islands (Malvinas), South Georgia (Georgia del Sur) and the South Sandwich Islands (Islas Sandwich del Sur), the South Orkney and South Shetland Islands, Bouvet Island (to Norway), Prince Edward and Marion Islands (South Africa), Crozet Islands, Kerguelen Islands (French Southern Territories), Heard and McDonald Islands (to Australia) and very locally on the Antarctic Peninsula.. Important populations exist at Isles Crozet (2.2 million pairs, including 1 million on Iles des Pingouins), Kerguelen (1.8 million pairs), Heard Island (1 million pairs), South Georgia (1 million pairs) and Marion Island (290,000 pairs). The population in the Patagonian Shelf region is estimated at 25,000 breeding pairs (Oehler et al. 2008, Kirkwood et al. 2007, Crossin et al. 2013). The Falkland Islands (Malvinas) population is estimated at no more than 1000 individuals (Stanworth ...
Population modelling, based on those breeding sites that have been accurately surveyed, indicates that between 1971 and 2007 (three generations) the number of Southern Rockhopper Penguins declined by 34% (BirdLife International 2010). In early 2016 there was a mortality of unknown extent of Rockhopper penguins in the Southwest Atlantic before and during the moulting period, with dead penguins (mainly caused by starvation) found along the coasts of Tierra del Fuego (around 300), the Falkland (Malvinas) Islands (300-400 on Saunders Islands) and near Puerto Deseado (around 200) (Andrea Raya Rey and Sarah Crofts, pers.com.). However, while the extent of this recent mortality is currently not assessable, it appears that it may have affected the population at a larger regional scale (Crofts and Stanworth 2016, A. Raya Rey, pers. comm.). Trend justification: A decline of 34% over the last three generations (30 years), as calculated from survey data, has been driven largely by the declines in the ...
We returned to the ship for a quick lunch while Plancius sailed to our next landing site at Grave Cove. Commersons dolphins came alongside the ship and frolicked in the waves by the gangway as we ate. After a short Zodiac ride we arrived at Grave Cove, where small colonies of Gentoo penguins and a couple of Magellanic penguins were waiting for us on the beach. After a wet landing in crystal clear water we met Marie-Paul, a Falklands resident who, with her partner, owns Grave Cove and the surrounding area. Marie-Paul kindly led us on a short walk across open grassy fields to a large Gentoo penguin colony on the other side of the island - the largest Gentoo colony in the Falkland Islands. The colony extended all the way to the beach, and this is where most of us spent the rest of the afternoon. The beach was incredibly exposed and atmospheric, with sea salt in the air and a breeze whipping whitecaps off the swell. Here we each found a spot to be still and watch or photograph the penguins

Ascent angles were not vertical and became shallower the closer the bird was to the surface (Fig. 4). According to equation 2, ascent angle is affected by buoyancy and downward lift. Penguins can control the ascent angle via the lift coefficient mediated by the attack angle of their flippers. If penguins kept the ascent angle steep and did not brake near the surface, then buoyancy would take them rapidly to the surface without flipper stroke effort. For example, the king penguin in Fig. 4A could reduce the 38 s ascent duration by 13 s by ascending vertically. Therefore, the oblique ascent angle and braking near the surface seem to be energetically expensive and do not accord with optimal diving theory predicting that animals maximize the proportion of time spent at the foraging depth (Kramer, 1988; Ydenberg and Clark, 1989). Why then might the birds delay a prompt return to the surface?. Wilson et al. (1996) hypothesized that an oblique ascent angle allows the birds to search both the vertical ...

Natural News) Chessington World of Adventures, a theme park, zoo and sealife center at Chessington, U.K., was recently accused of lying to its customers and remaining mum about a recent fox attack that killed eight of its Humboldt Penguins. According to reports, the attack happened at the end of June when an urban fox infiltrated the penguins enclosure. Following the incidence, the zoo management allegedly decided to quietly close off the Penguin Bay and put a sign at the entrance, stating that the unfortunate animals where placed somewhere else as the zoo made alterations to the attraction.. The zoo was accused of covering up the attack by using the sign. It was also reported that theme park employees were warned against talking about the incidence. The attack happened at the end of June when the night security and zoo staff were not monitoring as they should have been. There is CCTV footage on site at the park. The male penguins can be seen trying to protect the babies from the attack, sadly ...

The crafter can make a stuffed penguin doll, using flannel or felt fabric. This stuffed toy makes a good gift for children. Once the crafter gets to the point where she is ready to make and stitch the beak to the penguin's face, she needs to know how to make a beak that sticks out from the penguin face. She can also choose to make a flat beak shape and stitch this to the face after giving the beak some shaping. To make the penguin and attach the beak, the crafter should have basic sewing and crafting skills.

A number of factors have been suggested as affecting reproductive success in gulls. In this study we have attempted to isolate the effect of human disturbance on breeding success. We held other factors such as age of birds, terrain, and density of colony as constant as was practicable with a varied colony environment. There have been several previous discussions of the possible effect of human disturbance on the breeding success of birds. However, no study has documented this effect with controls. Reid (1968) found that in the Adélie Penguin (Pygoscelis adeliae) banding and close observation during seven summers caused the breeding populations in six colonies to decrease by more than 90%. Nelson (1966), commenting on nests on the fringe of colonies, stated that their lower success rates did not take full account of artifacts introduced by human disturbance. Working with the Sooty Tern (Sterna fuscata), Ashmole (1963:324) said that mortality caused by the pecking of chicks by adults was ...

Akihito, the emperor of Japan, has made a live appearance on national television saying he was deeply worried after the earthquake and tsunami that hit last Friday. The emperor made his announcement shortly after technicians working to stabilise a nuclear plant temporarily abandoned it as radiation started to surge.. The emperors appearance caused television stations to interrupt scheduled programming. During his appearance he said I hope from the bottom of my heart that the people will, hand in hand, treat each other with compassion and overcome these difficult times. The 77 year-old is deeply respected in Japan.. A statement by the Imperial household said Emperor Akihito and Empress Michiko want to visit the area affected by the tsunami, but the important thing now is rescuing the victims. In 1995 the emperor and empress visited Kobe after an earthquake struck and killed 6,400 people.. Around 10,000 people are feared to be dead after the earthquake and tsunami hit the north-east coast of ...

The very essence of work is changing, and so too is collaboration, including videoconferencing. Increasingly, people are working remotely. Those who work from offices these days often do so in open, shared spaces. When they need to do private meetings or interface with remotely located colleagues, customers, or partners, they may move to small conference rooms to do so. And now videoconferencing companies are delivering solutions they say are uniquely aimed at addressing the requirements of these so-called huddle rooms.

We think of the brand recognition every single day, and we also think about what Penguin Classics means as a brand to certain readers and audience, and respect that meaning deeply. As we fully engage in all opportunities we can digitally for Penguin Classics, we also feel strongly that our readers deserve high-quality books, both in content, editorial selection, apparatus, but also in terms of the physical book, with our choices of paper, our interior design and setting, and our overall book package design.. One of the most exciting approaches we take is working closely with our art department in terms of book design. Penguin Drop Caps is a new hardcover series in a design collaboration with our art director Paul Buckley and letterer Jessica Hische, whom we commissioned to create illustrated drop caps for each of our covers, pairing the love of typography and design with the love for books. A lot of bells and whistles with this one, foil-stamping on paper over board, a decorative stain on all ...
A breathing mask is joined with a head fastening device that has at least one headstrap and at least one neckstrap. The headstrap and the neckstrap are connected with each other in the area of their extensions away from the breathing mask. The headstrap is fastened to the breathing mask at the top, and the neckstrap is fastened to the breathing mask at the sides in the orientation of the breathing mask when it is being worn. Regions of the neckstrap that are located next to the breathing mask are connected with one another by a chinstrap. The chinstrap extends essentially in the longitudinal direction of the neckstrap. End segments of the neckstrap, which are arranged between the breathing mask and the places at which the neckstrap is connected with the chinstrap, run towards the breathing mask at an angle of inclination relative to the chinstrap, so that they move farther and farther away from the chinstrap as they approach the breathing mask.

Despite the ouster of the bakufu, no effective central government had been put in place by the rebels. On March 23, foreign envoys were first permitted to visit Kyoto and pay formal calls on the Emperor.[32] On April 7, 1868, the Emperor was presented with the Charter Oath, a five-point statement of the nature of the new government, designed to win over those who had not yet committed themselves to the new regime. This document, which the Emperor then formally promulgated, abolished feudalism and proclaimed a modern democratic government for Japan. The Charter Oath would later be cited by Emperor Hirohito in the Humanity Declaration as support for the imposed changes in Japanese government following World War II.[33] In mid-May, he left the Imperial precincts in Kyoto for the first time since early childhood to take command of the forces pursuing the remnants of the bakufu armies. Traveling in slow stages, he took three days to travel from Kyoto to Osaka, through roads lined with crowds.[34] ...

The Humboldt penguin, Spheniscus humboldti, has a plain white belly. It can have a few pure black spots on its belly and have orange with an hint of green. There are less than 10,000 Humboldt penguins in the wild. They are found in Chile and Peru. They drink sea water and their favourite food is small fish. A female Humboldt penguin can weigh up to 4.5kg and the male can weigh up to 6kg. Their bodies are adapted to life in water and most Humboldt penguins can live up to 20 years. They get their name from a famous Prussian explorer, Alexander von Humboldt. They have well dug burrows underground. In the past 100 years their droppings have been used as garden fertiliser. This dung is called "guano". ...

The king penguin stands at 70 to 100 cm (28 to 39 in) tall and weighs from 9.3 to 18 kg (21 to 40 lb).[4][5][6] Although female and male king penguins are monomorphic they can be separated by their calls.[7] Males are also slightly larger than females. The mean body mass of adults from Marion Island was 12.4 kg (27 lb) for 70 males and 11.1 kg (24 lb) for 71 females. Another study from Marion Island found that the mean mass of 33 adults feeding chicks was 13.1 kg (29 lb). The king penguin is approximately 25% shorter and weighs around 1/3rd less than the emperor penguin.[8][9]. At first glance, the king penguin appears very similar to the larger, closely related emperor penguin, with a broad cheek patch contrasting with surrounding dark feathers and yellow-orange plumage at the top of the chest. However, the cheek patch of the adult king penguin is a solid bright orange whereas that of the emperor penguin is yellow and white, and the upper chest tends to be more orange and less yellowish in the ...
