About These Birds
Negros Bleeding-heart
Medium ground dove, 25–28 cm, with brown upperparts and a distinct reddish breast spot, smaller than in Luzon Bleeding-heart. Endemic to Negros and Panay in the Philippines. Inhibits remnant lowland and hill forest. Critically Endangered; forest cover on Negros is near-exhausted, and the species may number fewer than 250 adults.
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.
