Factors affecting nest predation on forest songbirds in North America

摘要: Nest predation is an important factor in the ecology of passerines and can be a large source mortality for birds. I provide overview factors affecting nest North America with goal that it may some insight into management woodland birds United Kingdom. Although several influence productivity, success perhaps most widely measured demographic characteristic open-cup-nesting birds, usually largest cause failure. The identity predator species, how their importance varies habitat landscape factors, must known managers scientists to design effective conservation plans place research on appropriate context. Recent studies using video surveillance have made significant contributions our understanding relative different taxa America. Spatial temporal variation better understood when landscapes are placed biogeographical context local nest-site effects Low productivity resulting from high one potential causes bird population declines UK. ‘forest fragmentation paradigm’ eastern US not apply directly UK, thinking about avian demographics multiscale perspective, consideration knowledge dominant declines.
