About These Birds
Common Kestrel
Peneireiro-vulgar (Falco tinnunculus) — 32-38 cm. Falcão mais comum da Europa e Ásia, reconhecível pelo pairar estacionário com batimento rápido de asas enquanto caça. Macho com cabeça e cauda cinzentas e dorso castanho avermelhado manchado; fêmea mais barrada. Habita campos abertos, zonas costeiras e áreas urbanas. Alimenta-se de pequenos mamíferos, insetos e lagartos.
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
