About These Birds
Common Myna
Maina-comum (Acridotheres tristis) — 23-26 cm. Pássaro da família dos estorninhos originário do sul da Ásia, introduzido em numerosas regiões tropicais onde se tornou espécie invasora problemática. Plumagem castanho-escura com cabeça negra e marcas brancas nas asas. Vocaliza com grande variedade de sons. Onívoro oportunista extremamente adaptável.
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.
