A small songbird (Sylvia atricapilla) with a black cap on its head, common in Europe.
Compound of 'black' and 'cap' (Old English 'cæppe'). Named for the distinctive black markings on the male's head.
Blackcaps are incredible navigators that use the Earth's magnetic field and the sun's position to migrate thousands of miles—some populations have even changed their migration routes over just a few decades in response to climate change.
