Where do thrushes live in winter?
Its winter range is more southerly than the other west Siberian thrush species, extending well south into Africa in Mauritania, Egypt and Djibouti and into southern Iran and the Gulf States.
Are thrushes seasonal migrants?
All of the Winter Thrushes Survey study species are strong seasonal migrants but many are also resident in parts of their breeding ranges. Britain’s mild winters, relative to most of Europe, attract copious winter visitors to join our mainly resident populations: these are mainly of three species – Blackbird, Redwing and Fieldfare.
What is a Catharus thrush?
Catharus thrushes are mostly small, omnivorous or insectivorous, forest-related birds renowned for the males’ fluty songs ( Lowther et al., 2001 ). The genus contains twelve species, including long-distance migrants in North America and sedentary nightingale-thrushes in Central and South America ( Clement, 2000 ).
What can we learn from New World thrushes?
New World thrushes in the genus Catharus are small, insectivorous or omnivorous birds that have been used to explore several important questions in avian evolution, including the evolution of seasonal migration and plumage variation.
What kind of bird is Catharus?
Catharus is a genus of birds in the thrush family Turdidae. It contains the small, mostly insectivorous or omnivorous migrant thrushes of North America and the nightingale-thrushes of Central and South America. Its closest relative is the wood thrush of the monotypic genus Hylocichla, which is sometimes merged into Catharus.
What is a Calcariidae bird?

Four species have been recorded in New York. Until 2017, these species were considered part of the family Emberizidae.
What is the difference between Calcariidae and emberizids?

What birds live in an arid climate?
A fair number of the Cardinalidae are adopted to arid climates, including Blue Grosbeak (above) that prefers riparian edges and Pyrrhuloxia (left), which is a feature in the mesquite and cactus landscape of the American southwest. This particular Pyrrhuloxia was a vagrant to California.
What is a Cardinalidae bird?
Birders in North America are used to thinking about the Cardinalidae as the family with cardinals, grosbeaks, and buntings. This includes some of the most gorgeous plumages that we encounter, birds like Rose-breasted Grosbeak (left), Northern Cardinal (below left © Greg W. Lasley), and Lazuli Bunting (below center © John Sorensen).
How can I identify individual bird species?
Photos can be added to identify individual birds. Migration pattern can be calculated using information by months or years as needed. Range maps can be verified, allowing the users to see where the presence of individual bird species are expected to be at certain times of the year.
What is the average size of an emberizid?
Emberizids are small to medium sized birds 10 to 24 cm in length (15 cm on average). Towhees are the largest members of the family. Males are usually larger than females. Males and females are generally similar in appearance, however, where dimorphism occurs, males are brighter than females.
What habitat do emberizids live in?
Emberizids feed and nest in a wide variety of terrestrial habitats, in temperate, tropical and polar regions. They generally prefer open country and can be found in habitat from salt marshes at sea level to areas of alpine tundra at high elevation.

nonmigratory populations, and these nonmi- gratory birds have relatively small bones in the pectoral girdle. Wing length, measured on museum study skins, is not particularly representative of over- all body size (correlations with PC I scores range from 0.30 to 0.84 and are highest with scores
Can we measure body size in birds?
ORNITHOLOGISTS are frequently faced with the challenge of measuring body size in birds. A measure of overall size is required to test hy- potheses predicting patterns of geographic variation (e.g. Bergmann’s or Allen’s rules; James
