On cognitive conservation biology: Why chickadees leave a patch of woodland

Abstract

Although not previously emphasized, colonization of habitat patches by cognitive animals involves both decisions bringing an animal to a particular patch and decisions causing the animal to remain in the patch. We focus on the latter form of decision by examining the habitat and landscape correlates of persistence in chickadees (Poecile spp.) that we introduced into small woodlots previously cleared of conspecifics. The birds' decisions to remain were associated importantly with the presence of a canopy layer of large trees, and less so with area of the woodland patch and distance they had been transported from the capture site. The decision to persist was little related to landscape features near the focal habitat patch. The future holds promise for application of principles of cognition to landscape biology.
