About These Birds

Javan Cochoa

Common Blackbird

The common blackbird is one of Europe's most familiar and best-loved songbirds, celebrated for its rich, fluting song delivered from rooftop and treetop perches at dawn and dusk. Originally a shy woodland bird, it has colonized urban environments over the past two centuries and become one of the most successful urban adapters.
