About These Birds
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.
