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.
Papagaio-verdadeiro
The turquoise-fronted amazon is one of the most popular pet parrots in the world, prized for its ability to mimic human speech and its engaging personality. In the wild, these sociable parrots roost communally in large flocks and fly in pairs to feeding sites at dawn. Habitat loss and trapping for the pet trade threaten wild populations.
