December 13, 2015 – Yellow-throated Vireo (Vireo flavifrons)

Requested by: @gepwin

These large vireos are found in southern Canada and the eastern half of the United States, wintering in Central America, the Caribbean, and northern South America. They feed on arthropods, along with some fruits and seeds. Normally solitary, they form mixed-species flocks for migration. They build nests from bark, dry grass, pine needles, rootlets, and leaves, held together with spider silk, and require large forests to breed. Their numbers decrease drastically in forests under 250 acres.
