BREEDING THE RUFOUS-COLLARED SPARROW Zonotrichia capensis

摘要

According Clements (2007) the Rufous-collared Sparrow Zonotrichia capensis has 28 subspecies, whereas Howard & Moore (1980) listed 25. Not surprisingly perhaps, it has a wide geographical distribution, being found from the highlands of southern Mexico southwards to Cape Horn. The four other members of the genus, the White-crowned Sparrow Z. leucophrys, White-throated Sparrow Z. albicollis, Golden-crowned Sparrow Z. atricapilla and Harris's Sparrow Z. querula, breed in North America.
