January 14, 2016 – Blackcap, Black-capped Warbler, Eurasian Blackcap (Sylvia atricapilla)
These warblers are found in Europe, Asia, North Africa, and on several Atlantic islands. They eat mostly invertebrates in the breeding season and fruit at other times of year. Some populations in Europe seem to be adapting to human-provided food sources, wintering in the United Kingdom instead of southern Spain. These birds have developed rounder wings and narrower beaks, likely adaptations to their shorter migratory flights and different food sources. During courtship, males build multiple simplified nests. One may be selected as the actual nest and completed by the pair. Both parents incubate the eggs and raise the chicks together.
