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.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
