About These Birds

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.
Secretário
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
