About These Birds
Polynesian Imperial-pigeon
Polynesian Imperial-pigeon (Ducula aurorae), 43 cm. Pale grey-white head and underparts; dark metallic green upperparts. Endemic to the Society Islands (Tahiti, Maupiti) of French Polynesia. Inhabits montane and lowland forest. Endangered; heavy hunting and introduced predators have caused steep decline.
Felsentaube
Die Felsentaube ist die Stammform aller Haustaubenrassen und einer der häufigsten Vögel in Städten weltweit. Tauben dienten dem Menschen als Boten, Nahrungsquelle und Forschungsobjekt – ihre Orientierungsfähigkeit und ihr Sehvermögen wurden ausgiebig erforscht. Darwins Studien zur Taubenzucht trugen wesentlich zu seiner Evolutionstheorie bei.
