Snow Goose (Anser caerulescens) — Facts, Habitat & Conservation

Sobre

O ganso-branco é uma das aves migratórias mais numerosas da América do Norte, encontrada em duas fases de coloração: branca e azul. A fase branca tem plumagem branca com pontas pretas nas primárias, enquanto a fase azul tem asas escuras. Cria na tundra ártica e hiberna no sul dos Estados Unidos e no México. As populações têm crescido dramaticamente, causando degradação do habitat em locais de hibernada e paragens. Esforços de gestão incluem caça expandida para controlar os números.
