Barn Swallow only
Barn Swallow
Open farmland, meadows, and areas near water. Nests almost exclusively in human-made structures such as barns, bridges, and eaves.

Song & Call Comparison
Barn Swallow
A rapid, twittering song: a long stream of 'vit-vit-vit' and rolling chirps. Also gives a sharp 'vit' flight call. Song can last many minutes without pause. Musical and liquid.
Abutre-fouveiro
Generally silent; hisses and grunts at carrion with other vultures. Gives low croaking 'arrr' near nest. At colonies produces cackling and grunting — not melodic vocalizations.

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.
Abutre-fouveiro
The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.
