Eurasian blackcap

The blackcap is a small warbler with a sleek grey body and a distinctive head marking—males sport a black cap, while females wear a rusty brown one. Found across Eurasia and Africa, this bird fills woodlands with its complex, melodic songs that often build to a high, fluty finish.

• Males sing elaborate songs that rise to a clear, high-pitched finale.
• Females have a reddish-brown cap instead of the male's black one.
• Its closest relative is the garden warbler, though they look very different.
