I worked with a group of biologists associated with the Bird Genoscape Project who are concerned with the impact of a changing climate. We decided to investigate this question using yellow warblers. These migratory birds are found throughout most of Canada and the U.S. during the summer, inhabiting environments that range from the hot, dry Central Valley of California to the cool damp Pacific Northwest. If you live in North America, there are probably yellow warblers close by.
