About These Birds
Common Starling
Estorninho-malhado (Sturnus vulgaris) — 19-22 cm. Distribuído pela Europa e Ásia, introduzido na América do Norte, Austrália e África do Sul. Plumagem negra com reflexo metálico verde e roxo, com pontas brancas no inverno. Voo em bandos enormes (murmuração) é espetáculo notável. Excelente imitador. Omnívoro adaptável a ambientes urbanos e agrícolas.
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.
