Estimating the breeding population of Booted Eagles in the Cape Province, South Africa.

摘要: ABSTRA(;T.--Data on the breeding range of Booted Eagles (Hieraaetus pennatus) were collected over 25 yr in Northern, Western, and Eastern Cape Provinces, South Africa, to estimate population. Based distribution 150 known nest sites, we used information from digital terrain •nodels define topographical characteristics sites. This was identify total suitable nesting habitat study area. By calculating mean inter-nest distance, estimated population through extrapolation. With a distance 9.7 km, arrived at an 702 nests. In core areas that have studied intensively, found even higher densities therefore consider our be conservative.
