Size of Territories and Home Ranges of Male Western Yellow-breasted Chats (<em>Icteria virens auricollis</em>) in British Columbia

Abstract

McKibbin, René, and Christine A. Bishop. 2012 , the 95% kernel density estimation (KDE) revealed that mean area used by male Western Yellow-breasted Chats, as determined by radio-tracking (n = 5), was 1.16 ha, whereas the mean area as defined by observations of breeding males singing and perching was 0.62 ha (no statistical difference). Our hypothesis that the area determined by radio-tracking would be significantly larger than the area defined by observations of males singing and perching was rejected, but the area determined by radio-tracking was almost twice the area defined by observations of breeding males singing and perching.
