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.
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
