Habitat factors affecting bird family distribution in northern Michigan.

Abstract

The purpose of this study was to see if there was a correlation between tree species diversity and bird species diversity. We predicted that high tree species diversity would mean that there were more microhabitats for birds to specialize in; therefore high tree diversity index would be generally proportional to a high bird diversity index. We analyzed mist-net data and conducted point-center quarter sampling transects for tree species around the most productive nets. We compared diversity indices and frequencies for birds and trees and described the net habitats in terms of dominant tree species. These habitats were correlated with certain types of birds, including the warbler family (Parulidae).
