Spatial Ecology of Migratory Passerines on Temperate and Boreal Forest Breeding Grounds
[摘要] Information now available offers the hope of a more comprehensive and accurate understanding of the spatial ecology of breeding passerines. On the basis of recent research, we propose a model of space use in which individuals occupy defended territories embedded within potentially broader, multipurpose home ranges (
Powell 2000) that are extensively traveled and for which they have a detailed cognitive map. However, there remains a substantial lack of basic knowledge regarding the overall spatial ecology of breeding passerines. Thus, our review focuses on recent research that provides insight into space use by passerines from the prebreeding through premigratory periods. Building on this, we offer general observations on the nature of passerine space use, assess the extent to which socially monogamous passerines use areas beyond the boundaries of their territories, and suggest some important future directions for research involving passerines and for conservation in temperate and boreal forests.
