The winter range of populations of house finches in the Western United States is largely the same as the breed stove. small-scale migration does occur, with birds that breed in parts of northwest Montana observed to spend winters around 200 kilometer ( 125 michigan ) aside. migration from easterly and north-eastern regions, where firm finch populations have only become established in more holocene decades, than those native to the westerly U.S. are more probable to undertake more significant migrations, both to nearby towns at elevations lower than those of their breed ranges, and foster afield .

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
