British and Irish gardens fuel a novel reverse migration for Blackcaps in winter

The allure of garden feeders has transformed the biology of a bird that visits Britain and Ireland for the winter.

Increasingly mild winters and abundant garden bird food has led Blackcaps to establish new migratory routes, lead more sedentary winter lives, and perhaps even modify their anatomy.
