About These Birds
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
アオボウシインコ
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.
