December 27, 2016 – Willow Warbler (Phylloscopus trochilus)

These warblers are found in temperate Europe and Asia, migrating to sub-Saharan Africa in the winter. They eat insects and spiders, along with the eggs and larvae of both, picking their prey from foliage or catching it in the air. During the fall they also eat some fruits and other plant materials. Females do most of the construction of the dome-shaped nests, while males sometimes collect nesting materials. Using dry grass, leaves, moss, stems, lichen, twigs, and bark, along with hair and feathers for lining, they build the nests on the ground in grass, or near the base of a tree or bush. Females also perform the majority of incubation and chick feeding duties. Unusually for songbirds, they molt before each migration, a trip that can be as long as 7,456 miles (12,000 kilometers).
