About These Birds
Barnacle Goose
O ganso-pato é um ganso médio com face branca característica, coroa, pescoço e peito pretos, e corpo cinzento. Cria em penhascos íngremes nas ilhas árticas e hiberna nas zonas húmidas da Europa Ocidental, principalmente nos Países Baixos, Irlanda e Escócia. A legendária conexão com percevejos do mar levou à crença medieval de que nasciam de cracas. As populações cresceram consideravelmente nas últimas décadas.
Wandering Whistling-duck
O parreco-vagabundo é um pato assobiadeiro encontrado da Indonésia e Filipinas à Austrália. Tem a coloração castanho-avermelhada típica dos parrecos com flancos largamente barrados de castanho-escuro e branco. Habita zonas húmidas de água doce, incluindo lagos, pântanos e planícies inundadas tropicais. É gregário e frequentemente mistura-se com outras espécies de parrecos. Os bandos podem ser muito numerosos durante as estações não reprodutoras.
