A large (33 inches) waterbird, the Double-crested Cormorant is most easily identified by its black body and wings, long hooked bill, and orange chin patch. This species may be separated from the related Great Cormorant ( Phalacrocorax carbo) by that species larger size and large white chin patch, from the related Neotropic Cormorant (Phalacrocorax brasilianus) by that species smaller size and small white chin patch, and from the similar-looking Anhinga (Anhinga anhinga) by that species longer neck and tail. Male and female Double-crested Cormorants are similar to one another in all seasons. The Double-crested Cormorant breeds in scattered locations along the Pacific coast of North America from Alaska to Baja California, along the Atlantic coast from Newfoundland to Florida, in the northern Great Plains, and in the West Indies. Southern breeding populations tend to be non-migratory, while northern breeding populations migrate south to the coasts, the interior southeastern U.S., and Mexico. ...

Great cormorants eat fish and are known for their excellent diving skills. They forage in fresh as well as saline or brackish water. They can rotate their eyes, something most other birds are unable to do. Unlike other water fowl, their plumage is not oily. They absorb lots of water, so they need to spread their wings to dry after a swim. This bird has not had an easy life in the Netherlands. Because it was considered a rival for fishermen, they were shot, poisoned, chased away and even hung in huge numbers ...
Description. This is a medium-large black bird, 68-78 cm long and with a 95-110 cm wingspan. It has a longish tail and yellow throat-patch. Adults have a small crest in the breeding season. It is distinguished from the Great Cormorant by its smaller size, lighter build, thinner bill, and, in breeding adults, by the crest and metallic green-tinged sheen on the feathers. Among those differences are that a shag has a lighter, narrower beak; and the juvenile shag has darker underparts. The European Shags tail has 12 feathers; the Great Cormorant, 14 feathers. The green sheen on the feathers results in the alternative name Green Cormorant sometimes being given to the European Shag.. Habitat. It feeds in the sea, and, unlike the Great Cormorant, is rare inland. It will winter along any coast that is well-supplied with fish.. The European Shag is one of the deepest divers among the cormorant family. Using depth gauges, European Shags have been shown to dive to at least 45 metres. European Shags are ...

After you have reported a dead bird, you will be contacted to determine the condition of the bird and if it is suitable to be picked up for West Nile virus testing. All dead bird reports are used for surveillance purposes and are extremely valuable to us even if the bird is not submitted for testing.. If you have not been contacted within 24 hours of your report, you may safely dispose of the dead bird in your trash.. Although there is no evidence that West Nile virus can be acquired by handling dead birds, it is best not to handle the dead bird with your bare hands. Use gloves, a shovel, or a plastic bag to place the bird in a trash bag for disposal.. Please DO NOT freeze dead birds.. To find out what happens after you report a dead bird, see this link on the California Department of Public health website: http://westnile.ca.gov/wnv_faqs_basics.php?id=88.. ...
The increased use of neonicotinoid pesticides in the continental United States may have impacted bird populations and reduced bird diversity, according to a paper published in Nature Sustainability.. Bird biodiversity is declining at a marked rate. Bird populations in the United States have decreased by 29% since 1970, which has been attributed to various factors including the increased use of pesticides in agricultural production. Nicotine-based pesticides - known as neonicotinoids - have been used increasingly in the United States over recent decades. Previous research has shown that neonicotinoids are potentially toxic to birds and other non-target species. However, the impact of these pesticides on bird diversity in the United States is unclear.. Madhu Khanna and colleagues studied the effects of neonicotinoids on birds in the United States from 2008-2014. They analysed data from the North American Breeding Bird Survey to identify county-level changes for four different bird species groups - ...
Do you like to feed wild birds in winter? Follow these tips to keep your bird seed fresh.. Putting out bird feeders is a great way to attract more birds to your yard and garden in winter. There are some steps you need to take to ensure that the bird seed you are storing stays fresh and safe for the birds to eat, and to make sure your bird seed supply area stay neat and well stocked.. First, when purchasing seed for birds, avoid bird seed in burlap bags. Insects can easily get through the burlap and infest the bird seed. Mice and chipmunks and other rodents like to eat bird seed. Avoid buying bags that have obvious holes or have been patched. This means that somewhere along the supply chain, rodents have gotten into the bird seed.. At home, keep in mind that open bags of bird seed will attract rodents. When you open a bag of bird seed, transfer its contents into a heavy-duty plastic bin with a locking lid. A metal can with a tight lid will also work to store your bird seed. To store smaller ...

January 18, 2019. Time to start planning for spring. At the moment were well on the way through our programme of wintering bird surveys - vantage point surveys for wind energy developments, transect surveys on extensive sites and coastal surveys. There is still a little time to go before wintering birds will start to head north again. However, the breeding season is just around the corner, and this is a good time to plan for surveys.. Breeding bird surveys are increasingly recognised as an essential part of most environmental impact assessments. Many birds are recognised as priority species for the maintenance of biological diversity through the Natural Environment and Rural Communities Act in England and Wales, and Nature Conservation (Scotland) Act. As such, they are a key consideration in planning decisions. Bird surveys are of particular importance where a development may affect Special Protection Areas designated under the European Birds Directive, or Important Bird Areas recognised by ...

A new study revealed that urban birds dwelling amongst people are smarter than birds living in rural environments.. In a breakthrough study conducted by a team of McGill University researchers, it was found that city birds are good in innovative problem solving tasks and bolder compared to rural birds.. In addition, city birds have an edge over the rural birds because they adapted favorably to urban environments by exploiting new resources.. The study showed cognitive differences in problem-solving abilities for city birds versus the country. The study concluded that city birds are indeed smarter than rural birds.. This was affirmed by Jean-Nicolas Audet, a Ph.D student in the Department of Biology and first author of the study published in the journal Behavioral Ecology.. According to Mr. Audet, the study showed birds from urbanized areas are better at innovative problem-solving tasks than country bullfinches and have better immunity than rural birds.. The team expected that urban birds may ...

Bird trapping techniques to capture wild birds include a wide range of techniques that have their origins in the hunting of birds for food. While hunting for food does not require birds to be caught alive, some trapping techniques capture birds without harming them and are of use in ornithology research. Wild birds may also be trapped for their display in captivity in zoological gardens or for keeping as a pet. Bird trapping was formerly unregulated, but to protect bird populations most countries have specific laws and regulations. Almost all traps involve the use of food, water or decoys to attract birds within range and a mechanism for restricting the movement, injuring or killing birds that come into range. Food, water, decoy birds and call playback may be used to bring birds to the trap. The use of chemical sprays on crops or food can have more widespread effects and are not usually included in trapping techniques although there are some capture techniques that make use of bait with ...
The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorites lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists Union separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century. It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, ...

Joanne Oppenheim s Have You Seen Birds? is a classic that will continue to charm and engage young readers for years to come. Although it was originally published in 1968, Oppenheim partnered with illustrator Barbara Reid on this revised edition published in 1986. Over thirty years later, Oppenheim s text and Reid s plasticine illustrations are a pairing that is still invigorating and fun. Have You Seen Birds? was the winner of the Canada Council Children s Literature Prize (1986), the Elizabeth Mrazik-Cleaver Canadian Picture Book Award (1987), and the Ruth Schwartz Award (1986), among many other honors.. Have You Seen Birds? guides the reader on a rhythmic journey through a variety of different bird species, [l]ong legged tall birds, tiny bug-sized small birds (p. 4), always returning to the refrain Have you seen birds? This repetition provides a clear structure and can help young readers track their progress through the book rather than overwhelming them with the names of different bird ...
Birds are very popular pets. Many sought-after exotic birds come from other parts of the world. Because of the high prices associated with some of these breeds, the smuggling of exotic birds into the United States has become profitable and dangerous in terms of the chances of introducing diseases such as AI and END into the country.. The USDA quarantines and tests live birds imported into the United States to ensure that they do not have any foreign animal diseases such as the HPAI H5N1 virus. All imported live birds (except from Canada) must spend 30 days at a USDA quarantine facility where they are tested for the AI virus before entering the country. Returning U.S.-origin pet birds (except from Canada) also are tested and are home-quarantined. You must make a reservation at the chosen quarantine facility in advance by contacting the USDA port veterinarian.. To find out more about importing a pet bird, please see the APHIS Web site on animal imports. You may also find the publication Importing ...
Two street dogs died after eating dead chicken from a poultry farm in India… Azeri dog died from bird flu virus… Suspected bird flu outbreak leaves 4 dogs and about 100 chickens dead in Ivory Coast… Significant numbers of dogs in Thailand carry the H5N1 strain of the bird flu virus. These headlines have caused a lot of dog owners to be apprehensive. Given the fact that dogs are highly valued pets, any dog owner would fear for the health of the pet. What is bird flu? Are dogs really susceptible to this disease?. Avian influenza, commonly known as bird flu is an illness that is caused by any strain of the influenza virus that has adapted to a specific host. As the name suggests, the virus has adapted to birds. Bird flu is a highly transmissible disease of birds. This virus has a wide range of symptoms. While some species of wild birds can carry the virus without getting sick, other birds and poultry would get ill when infected. Infected poultry would show either of the two forms of the ...

Lets face it, most of us like to have birds around, but we have a problem with their droppings. The major complaint about bird droppings involve unsightly or smelly messes, concerns about property damage, as well as potential health risks.. Unsightly or Smelly Messes. Most of the time this is the real problem with bird droppings-we just dont want to see them. While that is certainly understandable, birds are part of our natural environment so we shouldnt be too upset about the occasional bird dropping on our car, house, or patio furniture. Bird droppings become more of a problem when we create structures like window sills, decks, or utility lines where birds come to sit frequently and do their duty. If bird droppings are accumulating the first thing to look at is how to alter the landscape so that the birds cant physically come and sit where they are making the mess. This may be done with architectural or structural modifications to a building or other structure, or by installing bird spikes ...

The European Bird Census Council (EBCC):. The European Bird Census Council (EBCC) officially adopted the HBW and BirdLife International Illustrated Checklist of the Birds of the World as their reference for nomenclature and taxonomy. It will be implemented in all of the supra-national projects coordinated by EBCC, including the European Breeding Bird Atlas, EuroBirdPortal and Pan-European Common Bird Monitoring Scheme.. With this latest resolution the HBW-BirdLife Illustrated Checklist increases its influence as the taxonomy and nomenclature followed by most European countries.. The European Union:. The European Union adopted the HBW and BirdLife International Illustrated Checklist of the Birds of the World as the standard reference for bird taxonomy and nomenclature. It is used most importantly for the EUs official list of birds, which guides the Birds Directive, whose goal is to protect all of the wild bird species naturally occurring in the European Union. This list is also used for the ...
Urban fauna communities may be strongly influenced by environmental and socio-economic factors, but the relative importance of these factors is poorly known. Most research on urban fauna has been conducted in large cities and it is unclear if the patterns found in these locations coincide with those from smaller human settlements. We examined the relative importance of environmental and socio-economic factors in explaining variation in urban bird communities across 72 neighbourhoods in 18 regional towns in south-eastern Australia. Native bird species richness varied from 6 to 32 across neighbourhoods and was higher in neighbourhoods with more nectar-rich plants. Variation in bird species diversity across neighbourhoods was also strongly positively related to the density of nectar-rich plants, but was higher also in neighbourhoods with higher socio-economic status (reflecting higher levels of disposal income, education and home ownership). The density of native birds across neighbourhoods per ...
The woodpecker has a distinctive long beak, which the woodpecker uses to make holes in trees. The woodpecker does this in order to dig out the grubs living under the bark. The average woodpecker is able to peck up to 20 pecks per second! The woodpecker is only able to peck so much and move its head so quickly without getting a headache due to the air pockets that help to cushion the woodpeckers brain. Woodpeckers are omnivorous birds and feed on a mixture of plants and animals (mainly insects). The woodpecker eats seeds, berries, fruits, nuts and bugs but the exact species of the woodpeckers food depends upon the area which the woodpecker inhabits. Due to their generally small size, woodpeckers have numerous predators in their natural environment that not only prey upon the woodpecker itself but also the woodpeckers eggs. The main predators of the woodpecker include wild cats, foxes, rats. snakes and large birds although many other species of animal will prey on the woodpecker too ...
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the status and trends of bird populations are critical for identifying and understanding many ecological issues and for developing effective science, management and conservation practices.. The BBL, since 1923 and in collaboration with the Bird Banding Office (BBO) of the Canadian Wildlife Service, administer the North American Bird Banding Program (NABBP), which manages more than 77 million archived banding records and more than 5 million records of encounters. In addition, each year approximately 1 million bands are shipped from the BBL to banders in the United States and Canada, and nearly 100,000 band ...
Many native Australian bird species are declining. Birds of garden, water, scrub and woodland are showing marked falls in their populations says a new report by Birds Australia (BirdLife in Australia). The encouraging news is that the status of some species is improving as a result of conservation action.. This is the sixth the state of Australias birds report, and presents an up-to-date overview of the health of bird populations in Australia and the main challenges to their sustainability. This 2008 report focuses on trends in bird populations revealed by around 50 long-term monitoring programs that have been running for up to 40 years.. Trends in bird populations are mixed, but more species are in decline than were reported in 2003. Common birds are far less common than they once were, for example populations of the familiar Australian Magpie Gymnorhina tibicen have slumped.. Many, and perhaps most, of our native birds are in decline for a range of reasons including habitat loss and ...
A new study shows for the first time that the alarming decline in insectivorous birds across the USA may be due to a decline of emergent insects in lakes and streams with poor water quality. These findings highlight the need for holistic conservation across terrestrial and aquatic ecosystems.

Gastrointestinal Helminth Parasites of Double-Crested Cormorants (Phalacrocorax auritus) at Four Sites in Saskatchewan, Canada, 2006-2007. Comparative Parasitology. 79:275-282. Interpretive Summary: Parasites are powerful indicators of ecological structure and interactions, particularly those involving foraging behavior and food habits. Identification of such linkages is dependant on the development of baseline data for distribution and host associations by various parasites on local to regional scales. As a cumulative process, such survey and inventory for faunal structure provides the foundations to explore ecological change and perturbations associated with climate and other forces. We provide the first data for parasite diversity in adult double-crested cormorants from breeding colonies on four very different lakes spanning a major ecotone (borderland between ecological zones) from prairie to boreal ...

Lake Naivasha is a freshwater lake in the Rift Valley North-West of Nairobi. The lake and its surrounding swamps, grass- and woodlands are home to a high diversity of wildlife, among them more than 400 bird species and a sizeable population of hippos. Floriculture forms the main industry around the lake and the largely unregulated use of lake water for irrigation is reducing the level of the lake.

If you see a youngish looking bird in the spring/summer season that presents with downy immature feathering and has short tail feathers it is a fledgling. You will notice most times that the bird is grounded and wandering around. To the observer the bird may appear injured or orphaned. The parent birds are close by and will go to their young to feed them. The parent birds are also teaching these young birds how to fly and forage. These young birds should be left alone. Put your cats and dogs inside!!!!! It should take no more than 3 days for the birds to start learning how to fly and be safely off the ground. In the interim of their education you can place the bird up in the crotch of a tree or somewhere safe off the ground to help protect the bird from predation.. ...
A bird house hung from a branch of a sycamore tree. Made from redwood, the tiny house had an opening cut just big enough for birds to fit in and nothing else. Several types of birds shared the feeder. Every evening three bluebirds, Azure, Indigo and Robin; three cardinals, Ruby, Scarlet and Carmine; and three canaries, Saffron, Topaz and Sunny, slept inside the house.. One morning Azure was the first bird to wake up. She yawned and stretched her wings. Hey, why does it seem more crowded in here? I used to be able to put my wings behind me and now I m squished. After a quick glance around the bird the bluebird climbed over all the other birds and squeezed through the hole. Time to find a worm. Only the early bird finds the worm. Hee hee. Off she flew.

You have probably watched birds at some point in your life, whether intentionally or simply while looking in your backyard, visiting a park or a national wildlife refuge, or hiking on a trail. A soaring Bald Eagle, an Acorn Woodpecker tapping on a dead snag, a Gadwall landing on a pond, a singing Wood Thrush - all of these conjure up strong images in our minds. Over 46 million Americans count ourselves as bird watchers, or birders. Being a bird enthusiast takes many forms. You may simply notice the birds you see on evening walks or keep a backyard feeder filled with tasty enticements. Perhaps you own a bird guide (or two or three), always have your binoculars within easy reach, or plan your vacations around spring warbler migration. Maybe you have a life list and know exactly how many birds are left to complete it. Or maybe you dont even keep track of what you see. Regardless of how we engage with birds and bird watching, many of us are thrilled daily to see our feathered friends. Birding ...
On the Isle of May between 1986 and 1996, the average adult survival of Shags Phalacrocorax aristotelis was 82.1%, Common Guillemots Uria aalge 95.2%, Razorbills Alca torda 90.5%, Puffins Fratercula arctica 91.6% and Kittiwakes Rissa tridactyla 88.2%. Shags, Razorbills and Puffins all had a single year of exceptionally low survival but these years did not coincide. In contrast, Kittiwake survival declined significantly over the period and there was evidence that substantial non-breeding occurred in several years. Breeding success of Kittiwakes also declined, which gives rise to concern for its future status. Given a high enough level of resighting, return rates (the proportion of birds known to be alive one year that were seen the next year) on a year-by-year basis provide a reasonable indication of relative changes in adult survival.. ...
Some birds are generalists. A generalist is an organism that can eat many different types of food. Other birds are highly specialized in their food needs and can eat just one type of food. Raptors such as hawks and owls are carnivores. They hunt and eat mammals and other birds. Vultures are scavengers. They eat the remains of dead animals, such as roadkill. Aquatic birds generally eat fish or water plants. Perching birds may eat insects, fruit, honey, or nectar. Many fruit-eating birds play a key role in seed dispersal, and some nectar-feeding birds are important pollinators. Bird beaks are generally adapted for the food they eat. For example, the sharp, hooked beak of a raptor is well suited for killing and tearing apart prey. The long beak of the hummingbird in Figure below was created to be able to sip nectar from tube-shaped flowers.. ...
Most bird eye injury occurs from the following:. 1. Interaction with another bird:. Injury due to interaction usually occurs when birds living in a multiple bird situation continually squabble, or have a fright that causes the birds to fly wildly about the cage. If two birds are observed to be continually fighting, they should not be housed together.. Multiple birds, particularly cockatiels, who are prone to frights, should only be housed in numbers in a very roomy flight cage. If they are kept in crowded conditions, injury will invariably occur.. Most eye injuries are treated with an opthalmic triple anti-biotic ointment or solution (make sure the product does not contain steroids to reduce swelling, as this can prove harmful to your bird).. If there is no apparent cut or bruising, or reason to think your bird suffered an injury-such as evidence of a fright, or observed physical aggression from another bird-your bird may have an eye disease, such as conjunctivitis or sinusitis, and this will ...

Avian influenza (AI) or bird flu is a group of viruses that occur naturally in birds. A virus is pathogenic if it can cause illness or death. Some AI viruses can infect birds but not cause many bird illnesses or death. Other AI viruses, termed highly pathogenic avian influenza (HPAI), can cause large numbers of bird illnesses and deaths. Currently there is concern about one of these viruses, known as highly pathogenic H5N1, because it is causing severe disease in chickens and other poultry on several continents. It has also been found in wild birds in the same areas. In some instances, people who have had close contact with sick poultry have also become infected and gotten very sick. Approximately half of the people known to be infected have died.. Source. This entry was posted on Monday, May 11th, 2009 at 7:31 am and is filed under Bird Flu.

Avian influenza, or bird flu, is a naturally occurring virus among birds. Wild birds are carriers of the virus but usually do not become ill from it. But avian influenza is extremely contagious and can cause domesticated birds like chickens and ducks to become sick and die. The particular subtype of bird flu that is currently circulating, H5N1, is deadly. Outbreaks of the disease have occurred in poultry in Vietnam, Thailand, Cambodia, China, Indonesia, Japan, Laos and South Korea. More than 100 million birds in these countries have died from the disease or have been killed (culled) in order to prevent its spread. In addition, there have been 108 cases of bird flu in humans and a total of 54 deaths. It is believed that humans become infected through contact with diseased birds and contaminated surfaces, including ingestion of raw or undercooked poultry. But much remains to be learned about specific modes of transmission ...
Double-crested cormorants (Phalacrocorax auritus ) collected in the Houston Ship Channel, Texas, USA, in November shortly after their fall migration contained residues of several industrial, agricultural, and petroleum contaminants including polychlorinated styrenes (PCSs), polychlorinated biphenyls (PCBs), DDE, and petroleum hydrocarbons. PCS concentrations in over-wintering birds collected in late February were three times higher than those in birds collected in November. PCB and petroleum concentrations remained at about the same level throughout the 3-month winter period. Petroleum hydrocarbons were present in all cormorants and residues in some individuals exceeded 25 ppm (wet weight). Mean DDE residues in samples collected in November and February were less than 1 ppm. Low concentrations of five other organochlorine compounds, not detected in cormorants collected in November, were recovered in birds collected in February....
In last months column, Understanding Bird Scent-Part 1…The Bird, we learned about how bird scent is created. We know that there are scent rafts that create four different scent clouds that carry the scent into the atmosphere. Once the scent is airborne, there are numerous atmospheric weather conditions that affect the scent dispersal and the ability of our pointing dogs to locate a bird. In this part, of our three part series, lets examine those weather conditions that affect bird scent diffusion. Well also look at the effect weather has on bird movement which also produces scent diffusion.. First, however, lets get the scent off the bird. Every warm living creature has natural body air currents. Warm air rises so the body air current of a bird goes from the bottom to the top of the bird. Those body air currents transport the scent rafts, and resulting cloud, up and into the atmosphere. Thats why we want our pointing dogs to carry their heads high…thats where pointing scent is most ...
Respiration rates of muscle mitochondria in flying hummingbirds range from 7 to 10 ml of O2 per cm3 of mitochondria per min, which is about 2 times higher than the range obtained in the locomotory muscles of mammals running at their maximum aerobic capacities (VO2max). Capillary volume density is higher in hummingbird flight muscles than in mammalian skeletal muscles. Mitochondria occupy approximately 35% of fiber volume in hummingbird flight muscles and cluster beneath the sarcolemmal membrane adjacent to capillaries to a greater extent than in mammalian muscles. Measurements of protein content, citrate synthase activity, and respiratory rates in vitro per unit mitochondrial volume reveal no significant differences between hummingbird and mammalian skeletal muscle mitochondria. However, inner membrane surface areas per unit mitochondrial volume [Sv(im,m)] are higher than those in mammalian muscle. We propose that both mitochondrial volume densities and Sv(im,m) are near their maximum ...

Corvids, members of the Corvidae family, range in length from 7.4 inches (19 centimeters) in Humes ground jay to the northern raven, which is 22.62 to 26.91 inches (58 to 69 centimeters) long. Humes ground jays weigh 1.47 to 1.61 ounces (42 to 46 grams). Northern ravens range from 2.02 to 3.43 pounds (.92 to 1.6 kilograms).. The Corvus genus of crows includes the crow, raven, jackdaw, and rook. These birds have shiny black plumage, feathers, and harsh calls. Jays are the colorful members of this family. The Eurasian jay and blue jay have blue and white feathers. Magpies are related to jays and plumage (feather) color is often described in the names of these birds, like the green magpie.. Corvids have strong bills. Most birds have black or dark bills, and feathers or whisker-like bristles cover the nostrils of many birds. Members of this family have large feet with strong toes. Birds use their toes to hold onto prey, the food that they hunt.. Corvids have long tails and rounded wings. Wing ...
As I discussed in the last column, we know that the majority of migratory bird species have an innate knowledge of where they should go to spend the winter. It boggles the mind to realize that many first-year birds find their way - unaided by adults - to a wintering habitat they have never seen. Travel instructions are encoded in their genes.. In considering how migratory birds find their way, we need to recognize two different abilities of birds. First, the birds have a well-developed sense of navigation. In other words, they can set a course and follow it, barring intervention from hurricanes or other weather phenomena.. Second, some birds have well-developed abilities of orientation. Most migratory birds can navigate well but fewer can orient.. A famous experiment done with European starlings in Eastern Europe nicely distinguishes navigation and orientation. Some starlings were captured and placed in a cage in the spring. This particular population of starlings is migratory. In the spring, ...
Wild birds have been implicated in the spread of highly pathogenic avian influenza (HPAI) of the H5N1 subtype, prompting surveillance along migratory flyways. Sampling of wild birds for avian influenza virus (AIV) is often conducted in remote regions, but results are often delayed because of the need to transport samples to a laboratory equipped for molecular testing. Real-time reverse transcriptase polymerase chain reaction (rRT-PCR) is a molecular technique that offers one of the most accurate and sensitive methods for diagnosis of AIV. The previously strict lab protocols needed for rRT-PCR are now being adapted for the field. Development of freeze-dried (lyophilized) reagents that do not require cold chain, with sensitivity at the level of wet reagents has brought on-site remote testing to a practical goal. Here we present a method for the rapid diagnosis of AIV in wild birds using an rRT-PCR unit (Ruggedized Advanced Pathogen Identification Device or RAPID,...

There are several species of mites called bird mites. These include the northern fowl mite (very common), the chicken mite, the American bird mite and many others. These mites are parasites on birds and are usually found on the birds or in their nests. Thus, under normal circumstances, bird mites go unnoticed. However, on occasion, bird mites wander away from the bird nests and are found indoors as accidental invaders.
Salmon biomass was an important predictor of several measures of breeding bird density and diversity. Our findings demonstrate that breeding birds may benefit from residual salmon-derived nutrients in landscapes adjacent to spawning grounds and that this trend extends beyond stream riparian zones to estuarine riparian forests, and well beyond the salmon spawning season.. Total bird density, Shannons index of diversity (which emphasizes richness and rare species) and the densities of insectivorous birds, golden-crowned kinglets and Pacific wrens were correlated strongly with salmon biomass. Nutrients from salmon probably affect breeding birds through several indirect pathways, including increased availability of emerged adult aquatic insect prey. Adults of aquatic invertebrates are found throughout forested habitats and are consumed by insectivorous birds in multiple foraging guilds [37]. However, aquatic invertebrates are highly variable in marine-derived nutrient enrichment owing to the ...
Then shall the priest command to take for him that is to be cleansed two birds alive and clean, and cedar wood, and scarlet, and hyssop: Leviticus 14:4 KJV. As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water: Leviticus 14:6 KJV. And he shall take to cleanse the house two birds, and cedar wood, and scarlet, and hyssop: Leviticus 14:49 KJV. And he shall take the cedar wood, and the hyssop, and the scarlet, and the living bird, and dip them in the blood of the slain bird, and in the running water, and sprinkle the house seven times: Leviticus 14:51 KJV. And he shall cleanse the house with the blood of the bird, and with the running water, and with the living bird, and with the cedar wood, and with the hyssop, and with the scarlet: Leviticus 14:52 KJV. And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of ...
With the start of this apparent range expansion in Idaho, we would like to document the progress of the population growth.. Birdwatchers have been an excellent resource for documenting Annas sightings, but there are limits to what we can learn by observing birds at feeders. At some feeders there are adult birds of different sexes, making identification of individuals simple. In many cases, multiple individuals have been found visiting one feeder. However, if multiple females or young birds are present it is difficult to determine whether there is more than one hummingbird visiting a feeder because they all look the same. It is also difficult for a birdwatcher to say whether the individual they spotted in September is the same individual they saw in March.. Thanks to reports from birdwatchers, during our first winter (2015-2016) studying Annas Hummingbirds in Idaho we (along with collaborator and hummbander Franceen Rudeen in eastern Idaho) confirmed reports of at least 55 individuals in the ...
Restoration projects to remove invasive plants free up needed space and resources for native plants and birds to thrive in a sustainable habitat. Native plants and native wildlife have a symbiotic relationship, where native birds serve as an indicator of healthy native habitats. For example, Least Bells Vireo- a federally endangered bird - nests in dense brush areas of native mule fat or native coyote brush. By restoring the ecological health of the area, we are contributing to the breeding success of this bird and others - birds that live in the area year-round as well as those migrating in both the spring and fall. There are many different non-native and invasive plants at the Basin that have posed issues to native wildlife year in and out. Annual non-native mustards-like shortpod mustard (Hirschfeldia incana) and black mustard (Brassica nigra) can grow to 6′ tall and create a dense, almost impenetrable thicket. This layer of biomass hides the invasive horehound (Marrubium vulgare). The ...

What do birds have that other animals dont? Feathers! Birds ability to fly has allowed them to spread throughout the world. Birds lay eggs, are warm blooded, have a light but strong skeleton and a highly efficient respiratory system. The bones of birds are hollow to reduce weight. They are not hollow like a tube, more like a tube with a criss-cross of support columns and diagonal beams. The bone is very strong. In some species, the bones are part of the respiratory system. Air circulates through the bones to help control the body temperature. Bird species have a wide variety of diets. Some eat grasses; others eat insects, small mammals, and even larger mammals. Birds have a variety of colors. Most of the males are very colorful to attract females. In most cases, the female color is fairly drab which allows them to be camouflaged while protecting eggs in the nest..

Although not listed as endangered or threatened at the federal level, the Dickcissel is a Partners in Flight priority grassland species and is included on its Watch List. While its overall population is still large, the species has shown significant declines in many states.. ABC is working with landowners, agencies, and a variety of programs, including Migratory Bird Joint Ventures, to preserve habitat for Dickcissels. (See how the Oaks and Prairies Joint Venture is helping to restore grasslands in Texas and Oklahoma.) Our new BirdScapes approach, which aims to save breeding, wintering, and stopover habitat for migratory birds, will provide another boost for this species.. ABC and partners filed suit against the Environmental Protection Agency in 2016, alleging insufficient federal regulation of neonicotinoid pesticides, which are toxic to birds, bees, and other wildlife. A 2013 study by ABC found that even tiny amounts of neonics are toxic to Dickcissels and other grassland bird species such ...
We demonstrated replication of a nonpoultry avian influenza A(H9N2) virus in finches and parakeets with limited environmental shedding (water), but no transmission to cage mates. Shedding routes were more limited, virus titers lower, and clinical signs less frequent in pet birds than in chickens. Nevertheless, the potential for pet birds to act as vectors of the virus should not be underestimated. We recently showed that novel influenza A(H7N9) virus transmits between passerines, which include finches, and poultry by water despite a lack of intraspecies transmission (8); H9N2 virus has also been isolated from wild, finch-like birds in China (11).. Interspecies transmission of the Env/9306 strain remains a risk to mammals because of adaptation mutations (5,9) and is supported in this study by replication in ferrets and in human and swine tissues. Physical contact between pet birds and their owners, as well as shedding of virus into the environment (water), could be transmission sources.. Live ...
Like humans birds too show many different behaviors that are associated with sexual maturity and hormonal fluctuations. During breeding season, which is fixed in most birds depending upon the local climatic conditions, they behave instinctively in distinct ways under the powerful influence of sex hormones. How a bird would react sexually depends on various factors that include seasonal changes in daylight hours, diet, interaction with owners or favourite toys and objects (in case of pets), environmental influences. Such behaviours, sometimes very strange, are not necessarily associated with every bird. Masturbation is one such act which is usually associated with humans, but it is not exclusive to them. A few bird species have been reported to masturbate in the wild. They include budgerigar, cockatiels, spectacled parrotlets, a northern lapwing, and American Avocet. To masturbate, birds resort to rubbing their cloaca or vent (underneath the tail) on their favourite objects. In the case of pet ...

During their fall migration south, thousands of chimney swift birds (Chaetura pelagica) gather in a tornadolike flock at dusk before dropping down a chimney-five birds at a time-to roost for the night. But unlike European starlings, which form massive daily flocks called murmurations, chimney swifts are flocking amateurs that spend most of the year in small groups. To understand how the birds manage this complex and rapid descent, researchers focused three cameras on an 1800-strong flock of chimney swifts as they funneled into an industrial chimney in downtown Raleigh, North Carolina. By mapping the 3D position of each birds flight path, they found that swifts adjust their route based primarily on their closest flying neighbors, and ignore birds that are farther away, they report today in the Proceedings of the Royal Society B. Whereas the outer circling is neat and orderly, cooperation breaks down as birds near the chimney, and they make a dash for the opening to get the best roosting sites. ...
