The genomics era has produced an arsenal of resources from sequenced organisms allowing researchers to target species that do not have comparable mapping and sequence information. These new non-model organisms offer unique opportunities to examine environmental effects on genomic patterns and processes. Here we use comparative mapping as a first step in characterizing the genome organization of a novel animal model, the white-throated sparrow (Zonotrichia albicollis), which occurs as white or tan morphs that exhibit alternative behaviors and physiology. Morph is determined by the presence or absence of a complex chromosomal rearrangement. This species is an ideal model for behavioral genomics because the association between genotype and phenotype is absolute, making it possible to identify the genomic bases of phenotypic variation. We initiated a genomic study in this species by characterizing the white-throated sparrow BAC library via filter hybridization with overgo probes designed for the chicken,
White-Crowned Sparrow - Zonotrichia leucophrys - also known as Le bruant à couronne blanche (French), Witkruingors (Dutch), Dachsammer (German), Passero corona bianca (Italian), and Chingolo Piquiblanco (Spanish).. Song Sparrow - Melospiza melodia - also known as Bruant chanteur (French), Zanggors (Dutch), Singammer (German), Passero cantore (Italian), and Chingolo Melodioso (Spanish).. This is the first time I have seen a White-Crowned Sparrow in my yard. The Song Sparrows have been here before, but there appears to be a pair hanging around a lot this Spring. In fact, I even saw one Song Sparrow peaking into my gourd birdhouse, although I do not think a Song Sparrow would nest in a gourd up in an apple tree..

One of the continents best-studied and most familiar songbirds, the White-throated Sparrow is found at some season throughout much of North America south of the tree line and principally east of the Rocky Mountains. To many its distinctive whistled song is synonymous with the northern wilderness. During migration and throughout its winter range, this species is a common visitor at feeding stations. It breeds primarily in the boreal coniferous and mixed forest and, a short-distance migrant, winters mainly in the southeastern U.S. A habitat generalist, it tends to occur in shrubby edges or early successional stages or openings in the forest, nesting and foraging for seeds and insects on or near the ground.. Throughout its extensive range the White-throated Sparrow shows no subspecific variation. However, it exhibits plumage polymorphism (white-striped and tan-striped morphs - see color photos) in both sexes, most obvious in the breeding season, associated with a difference in an autosome. These ...

In this paper, we describe spatial variation in the demography of the Song Sparrow Melospiza melodia. Long-term population studies of birds have generally considered only single sites in optimal habitat, but recent theory has shown the value of taking spatial variation in population dynamics into account. In this theory, collections of local populations in habitat patches connected by dispersal are defined as metapopulations. We review metapopulation models briefly and then use these ideas in a study of the Song Sparrow. Sparrows were studied on islands of varying size and degree of isolation from the North American continent. For analysis, these islands are grouped into three areas. Sparrows on the isolated Mandarte Island usually reproduced and survived well over 17 years but suffered from catastrophic mortality in some winters. After such events, the population recovered quickly without much immigration. Sparrows on smaller islets near Mandarte also survived and reproduced well during 4 ...
Avian malaria parasites are a highly diverse group that commonly infect birds and have deleterious effects on their hosts. Some parasite lineages are geographically widespread and infect many host species in many regions. Bird migration, natural dispersal, invasive species and human-mediated introductions into areas where competent insect vectors are present, are probably the main drivers of the current distribution of avian malaria parasites. A total of 412 and 2588 wild house sparrows (Passer domesticus) were captured in 2012 and 2013 in two areas of the Iberian Peninsula (central and southern Spain, respectively). Genomic DNA was extracted from blood samples; parasite lineages were sequenced and identified by comparing with GenBank and/or MalAvi databases. Thirteen Plasmodium lineages were identified in house sparrows corresponding to three major clades. Five individuals were infected by the African Plasmodium lineage PAGRI02, which has been proposed to actively circulate only in Africa. Despite the
The diminutive house sparrow (Passer domesticus) is perhaps one of the earliest birds you can remember from your childhood. Their nests dotted almost every house in the neighbourhood as well as public places like bus bays and railway stations, where they lived in colonies and survived on food grains and tiny worms. Many bird watchers and ornithologists recall with fondness how the house sparrow gave flight to their passion for observing birds. The association between humans and the house sparrow dates back to several centuries and no other bird has been associated with humans on a daily basis like the house sparrow. It is a bird that evokes fond memories and has thus found mention in folklore and songs from time immemorial. Unfortunately, the house sparrow is now a disappearing species. But like all other plants and animals which were once abundant and are now facing an uncertain future, their numbers are also declining across their natural range. Certainly, there is no one single reason for the ...
White-throated sparrows (Z. albicollis) are short-hop migrants that winter primarily in the south eastern United States and breed in the north eastern United States and in Canada. We caught white-throated sparrows that were overwintering in Mississippi in January (N=18) as well as sparrows that were migrating through southern Ontario in both autumn (N=36) and spring (N=17) [described previously by McFarlan et al. (McFarlan et al., 2009)]. These sparrows were caught in the morning with mist-nets, and killed immediately after capture by cervical dislocation under brief (,1 min) isoflurane anaesthesia; a sample of the left pectoralis muscle was immediately removed and stored in liquid nitrogen until transfer to a -80°C freezer (for quantitative PCR, qPCR). Muscle mass was not measured in these sparrows. Autumn sparrows were aged according to the degree of skull ossification (Pyle, 1997).. Another set of white-throated sparrows was captured during autumnal migration in southern Ontario and kept in ...
The effect of fenitrothion exposure on birds was examined by measuring aerobic metabolism, blood hemoglobin content, plasma cholinesterases, and body weight for up to 21 d postdose. Peak metabolic rate was measured in a flight chamber in three-dose groups of house sparrows (Passer domesticus; 100 mg/kg = high, 60 mg/kg = medium, 30 mg/kg = low) and one-dose groups of zebra finches (Taeniopygia guttata; 3 mg/kg) and king quails (Coturnix chinensis; 26 mg/kg). Aerobic metabolism was measured during 1 h of exposure to subfreezing thermal conditions in low-dose house sparrows and king quails (26 mg/kg). Fenitrothion had no effect on metabolic rate during cold exposure or on blood hemoglobin at any time. By contrast, aerobic performance during exercise in sparrows was reduced by 58% (high), 18% (medium), and 20% (low), respectively, 2 d postdose. House sparrows (high) had the longest recovery period for peak metabolic rate (21 d) and plasma cholinesterase activity (14 d). House sparrows (high) and treated
We found that migratory adult white-crowned sparrows had relatively more and a higher density of new hippocampal neurons than adult non-migratory white-crowned sparrows. This difference does not appear to be global, as the number and density of doublecortin-positive cells in an adjacent region (HA) did not differ among subspecies. This is consistent with the results of Pravosudov et al. [12] in that, in these same individuals, migratory sparrows had more total hippocampal neurons than non-migratory sparrows but with comparable absolute hippocampal volumes. Thus, taken together, adult migratory sparrows had a higher density of both new and total number of neurons in the hippocampus compared with adult non-migrants. Similarly, Cristol et al. [11] found that migratory juncos had a higher density of hippocampal neurons than non-migrants, although they did not address the age of these neurons. Previous studies have not documented the mechanism underpinning these differences, but our results suggest ...
With the advent of next generation sequencing, new avenues have opened to study genomics in wild populations of non-model species. Here, we describe a successful approach to a genome-wide medium density Single Nucleotide Polymorphism (SNP) panel in a non-model species, the house sparrow (Passer domesticus), through the development of a 10 K Illumina iSelect HD BeadChip. Genomic DNA and cDNA derived from six individuals were sequenced on a 454 GS FLX system and generated a total of 1.2 million sequences, in which SNPs were detected. As no reference genome exists for the house sparrow, we used the zebra finch (Taeniopygia guttata) reference genome to determine the most likely position of each SNP. The 10 000 SNPs on the SNP-chip were selected to be distributed evenly across 31 chromosomes, giving on average one SNP per 100 000 bp. The SNP-chip was screened across 1968 individual house sparrows from four island populations. Of the original 10 000 SNPs, 7413 were found to be variable, and 99% of ...

To evaluate transmission dynamics, we exposed 25 bird species to West Nile virus (WNV) by infectious mosquito bite. We monitored viremia titers, clinical outcome, WNV shedding (cloacal and oral), seroconversion, virus persistence in organs, and susceptibility to oral and contact transmission. Passeriform and charadriiform birds were more reservoir competent (a derivation of viremia data) than other species tested. The five most competent species were passerines: Blue Jay (Cyanocitta cristata), Common Grackle (Quiscalus quiscula), House Finch (Carpodacus mexicanus), American Crow (Corvus brachyrhynchos), and House Sparrow (Passer domesticus). Death occurred in eight species. Cloacal shedding of WNV was observed in 17 of 24 species, and oral shedding in 12 of 14 species. We observed contact transmission among four species and oral in five species. Persistent WNV infections were found in tissues of 16 surviving birds. Our observations shed light on transmission ecology of WNV and will benefit ...

Behaviors associated with breeding are seasonally modulated in a variety of species. These changes in behavior are mediated by sex steroids, levels of which likewise vary with season. The effects of androgens on behaviors associated with breeding may in turn be partly mediated by the nonapeptides vasopressin (VP) and oxytocin (OT) in mammals, and vasotocin (VT) in birds. The effects of testosterone (T) on production of these neuropeptides have been well-studied; however, the regulation of VT receptors by T is not well understood. In this study, we investigated steroid-dependent regulation of VT receptor (VTR) mRNA in a seasonally breeding songbird, the white-throated sparrow (Zonotrichia albicollis). We focused on VTR subtypes that have been most strongly implicated in social behavior: V1a and oxytocin-like receptor (OTR). Using in situ hybridization, we show that T-treatment of non-breeding males altered V1a and OTR mRNA expression in several regions associated with seasonal reproductive ...
In Canadas boreal forest, the impact of timber harvesting on bird populations is complicated, differing by species, region, forest type, harvest prescription, length of time after harvest, and so on. Forest harvesting may cause changes in bird species composition, diversity and abundance, and these changes can be positive, neutral or negative, depending on the species and the types of habitat that it uses.. For example, early successional species such as mourning warbler (Oporornis philadelphia), chestnut-sided warbler (Dendroica pensylvanica) and white-throated sparrow (Zonotrichia albicollis) benefit from harvesting, as they prefer a younger forest. But some forest-dependent species, such as brown creeper (Certhia Americana), boreal chickadee (Poecile hudsonica) and ovenbird (Seiurus aurocapilla) are sensitive to the loss of old forest habitat.. Other species, such as woodpeckers, require dead or dying trees for nesting and feeding, while others require the cavities created by woodpeckers in ...
Graduate research will be expected to combine traditional behavioral ecology studies with next-generation sequencing technology to examine the evolution of polymorphism in the white-throated sparrow. Student will conduct extensive laboratory work as well as participate in field based data collection during the breeding season. This species exhibits a clear link between phenotype and genotype, making it an ideal system in which to pinpoint the determinants of complex sexual and parental behavior. We have amassed 29 years of detailed data on this species making it possible to identify the genetic, epigenetic, and environmental bases of behavior. Morphs of the white-throated sparrow provide a unique opportunity to study intraspecific genomic differences, which have resulted from two separate, yet linked evolutionary trajectories. Such results can transform our understanding of the evolution of genomes ...

Home ranges for Gambels quail on our study site were strongly associated with riparian habitat and averaged 954 acres, and ranged in size from 403 ha to 1,651 acres.. Along riparian habitat, Gambels quail are often found near dense stands of fourwing saltbush, wolfberry, mesquite, Greggs catclaw, and other woody riparian vegetation. Gambels quail also utilize riparian habitats that have been invaded by salt cedar, although these habitats generally lack diversity in food items for quail.. Nesting typically begins in April and lasts until June or July. Males seem to have no role in incubation, but maintain strong interest as they remain close to the nest to defend it from potential predators. Females generally construct a bowl-shaped nest lined with small twigs, grass, leaves, and feathers. Eggs are dull white, smooth and often contain brown spots. Clutch sizes average between 10 and 14 eggs. During dry years clutch sizes are often reduced and may contain as few as five eggs. Occasionally, ...

Kyle Wellband and I departed for the field on May 30, 2008. Since that time, weve only had two rain days (this is one of them and I am currently typing from the public library in Edmundston). Weve been lucky enough to get a lot of atlassing done and have been able to point count nearly every day (weve completed point counts in 16 squares so far and hope to get a lot more done by the July 3rd deadline). There have been many highlights along the way-far too many to list them all here but Ill mention a few. Kyle has developed a true talent for finding White-throated Sparrow nests and has already found three nests-two with eggs and one with young. Weve also found a Spotted Sandpiper nest with four eggs, a Hermit Thrush nest with eggs and a few Eastern Phoebe, Yellow-bellied Sapsucker and Hairy Woodpecker nests as well. Weve also found Cliff Swallow colonies (one right in the parking lot of Irvings Deersdale camp) and also a likely Chimney Swift breeding and roosting site (a big hollow tree in ...
Population genetic structure and intrapopulation levels of genetic variation have important implications for population dynamics and evolutionary processes. Habitat fragmentation is one of the major threats to biodiversity. It leads to smaller population sizes and reduced gene flow between populations and will thus also affect genetic structure. We use a natural system of island and mainland populations of house sparrows along the coast of Norway to characterize the different population genetic properties of fragmented populations. We genotyped 636 individuals distributed across 14 populations at 15 microsatellite loci. The level of genetic differentiation was estimated using F-statistics and specially designed Mantel tests were conducted to study the influence of population type (i.e. mainland or island) and geographic distance on the genetic population structure. Furthermore, the effects of population type, population size and latitude on the level of genetic variation within populations were ...

After the chicken, the House Sparrow is the most widely distributed bird species in the world, occurring on all continents except Antarctica and on most human-inhabited islands. Although its Latin name is Passer domesticus, it is certainly not domesticated. In fact, it is widely regarded as a pest species and is consequently not protected in most of its extensive range.
A unique study of the white-throated sparrow has identified a biological pathway connecting variation in the birds aggression and parenting behaviors in the wild to variation in their genome.
His urge to attack could be triggered even when he was not hungry, and when triggered it was energetic and persistent. With little or no apparent prior coaching, he attacked crows only after watching them intently as if to determine whether or not they were watching him. When they were watching him or looked at him, he did not attack, nor did he continue an attack when his potential victim, such as a crow, looked up, indicating that it had seen him approaching. Nevertheless, he vigorously pursued fully feathered young blue jays and white-throated sparrows that were aware of him and trying to escape, although their flight was clumsy. Without obvious prior experience, he instantly attacked the very first injured squirrel that he saw, whereas healthy noisy ones were only watched and never attacked. Although I often saw birds noisily mobbing directly in front of him (within one-half to one meter) I did not see him make a single attempt to capture any of them. It was not lack of hunger that kept him ...
After reading the application and interagency comments, here is what I discovered.. In March, the Department of Inland Fisheries and Wildlife updated its list of species of special concern.. This lists species suffering a reduction of numbers, loss of habitat and/or major impacts from development.. Within the proposed project footprint, a total of 21 species are endangered or of special concern. They include the wood thrush, veery, scarlet tanager, American redstart, black and white warbler, chestnut-sided warbler, yellow warbler, white-throated sparrow, northern parula, barred owl, eastern towhee, prairie warbler and olive-sided flycatcher.. Also included are the hoary and silver-haired bats. New studies show migratory or tree-roosting bats are attracted to insects that are drawn by the lighting and heat of the structures housing the wind-turbine generating components, causing an increase in bat strikes.. The bald eagle, Northern harrier and peregrine falcon were observed during the survey. ...
The Sonoran desert is home to this distinctive bird. Gambels Quail is often abundant near desert streams and waterholes, with coveys walking to the water in the morning and evening, giving a variety of clucking and crowing notes. As cities have grown in the desert southwest, these birds have adapted to life in the surrounding suburbs, coming into back yards to eat grain scattered for them. At night, coveys of Gambels Quail roost in bushes or low trees.
Learn how to identify Song Sparrow, its life history, cool facts, sounds and calls, and watch videos. A rich, russet-and-gray bird with bold streaks down its white chest, the Song Sparrow is one of the most familiar North American sparrows. Dont let the bewildering variety of regional differences this bird shows across North America deter you: its one of the first species you should suspect if you see a streaky sparrow in an open, shrubby, or wet area. If it perches on a low shrub, leans back, and sings a stuttering, clattering song, so much the better.
The Eurasian Tree Sparrow is actually a species of Old World sparrow, or sparrow that occurs in Europe and Asia. It is closely related to house sparrows, and not so closely related to our own American tree sparrow. In 1870, a group of 12 of these birds were imported from Germany and released in Lafayette Park in St. Louis, to increase the diversity of the local bird life. All of the Eurasian Tree Sparrows in the United States today are descended from these twelve birds. What makes them different from the house sparrow, which is an Old World species that has expanded its range to include the whole of the US, is that the Eurasian Tree Sparrow population is confined to the St. Louis area, with their range extending somewhat into western Illinois and up into southeast Iowa. This is the only place in the U.S. they occur. Many of the local birders see these birds frequently, but for anyone else in the country, they are not seen at all. People from all over the U.S. come to St. Louis to see this little ...
Another other field of my research seeks to understand how organisms balance their energy allocation into growth, self-maintenance, and reproduction. These life history trade-offs are fundamental in biology, but still not well understood. In particular I find it interesting to investigate the relationships between growth, body sizes and telomere dynamics at early age, and how these early experiences might interfere with the organisms lifespan and lifetime reproductive success.. The main study system for my research has been an archipelago located at Helgeland in northern Norway consisting of 18 island populations of House sparrows (Passer domesticus) where the spatial structure of the archipelago form a metapopulation. In addition we conduct experimental studies in several other insular populations along the coast of northern Norway. Since 1993 "the House sparrow project" has collected an impressive data set that provides unique opportunities for in-depth studies within eco-evolutionary ...

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence ,20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (,30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (,10,000 mature individuals with a continuing decline estimated to be ,10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern ...
Vehrencamps work also suggests that males that are most successful are those that share many song types with their territorial neighbors. Song sparrows, for example, can learn songs only within a narrow time period restricted to the first few months after fledging, which means that males must learn neighborhood songs quickly to facilitate successful territorial negotiations.. "Song sparrows are very restricted learners, so the dominant birds that acquire territories within their natal area share more song types with their neighbors and survive better," explained Vehrencamp, who observed that birds with a low degree of song-sharing spend more time fighting with neighbors and are rarely seen the next breeding season.. Vehrencamp also studies the banded wren in Central America. This species has a longer learning period, up to a year or more, so all birds in the neighborhood share a large fraction of their song types. "Males get up early, and sing vigorously with frequent song-type matching in ...
Most birds are either diurnal or nocturnal. The Manx shearwater is one of the very few that regularly perform such normal activities as feeding, hunting, and flying by day, and other activities, such as homing to the nest, by night. The retinal structure of the Manx shearwater is compared with that of a diurnal passerine (house sparrow) and a diurnal sea-bird (fulmar petrel), in order to determine what features are common to sea-birds and what, if any, may be specific adaptations to vision over a wide range of light intensity. Both sea-birds have a linear area centralis but lack a fovea. The rods of the dark-adapted fulmar and shearwater show great difference of shape from those of the light-adapted. The shearwater has more rods at the area centralis, a larger rodparaboloid in the dark adapted retina, and a greater ratio of total number of visual cells to ganglion nuclei than has the fulmar.. ...

California is famous for its endless sunny warmth, but these last several years of ongoing drought conditions have amplified that. Every year the draught continues, a "next normal" is established, but even so, there are many familiar bench-marks that indeed, announce that spring is upon us.. Even with just the little rain weve received, one can watch the surrounding hillsides transform to swatches of soft green, and when Coldwater Creek flows, there is a welcomed energy that recharges the landscape of Glen Ivy. Wild Cucumber vines spread and climb on everything with a burst of small white flowers, and Flowering Jasmine spiral above the Kiosk. Along the back road in the Spiral, daffodils push up from the garden with their yellow trumpet flowers and plump strawberries sweeten in the soft spring sun..

Several regions of the human genome are highly variable in populations because the number of repeats in these regions of a short minisatellite sequence varies at high frequency. Different minisatellites have a core sequence1,2 in common, however, and probes made up of tandem repeats of this core sequence detect many highly variable DNA fragments in several species including humans1,3, cats4, dogs4 and mice5. The hypervariable sequences detected in this way are dispersed in the genome and their variability means that they can be used as a DNA fingerprint, providing a novel method for the identification of individuals2,6, confirmation of biological relationships7,8 and human genetic analysis9,10. We show here that human minisatellite-derived probes also detect highly variable regions in bird DNAs. Segregation analysis in a house sparrow family confirms that these regions comprise many mostly heterozygous dispersed loci and we conclude that house sparrow DNA fingerprints are analagous to those ...
