About These Birds
Barn Swallow
The barn swallow is the most widespread swallow species in the world and has one of the longest migrations of any passerine. Its arrival signals spring across the Northern Hemisphere, inspiring cultural references from ancient Greece to modern poetry. Barn swallows have become almost entirely dependent on human structures for nesting.
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.
