Indirect effects of climate change and forest fragmentation on breeding bird abundance in Ontario

Abstract

From data on forest breeding bird species in the Atlas of Breeding Birds of Ontario, this thesis summarizes population changes from 1981 to 2005 and all the direct and indirect reasons that may lead to the decline of these bird species. The decline and shift in the distribution of forest breeding birds in some parts of Ontario are related to rising temperatures and forest fragmentation caused by climate change.
