I examined three aspects of forest fragmentation to determine how they impact resident and migrant bird species. The first aspect was the relationship between habitat patch area and species presence and richness. I performed an observational study along riparian woodlands to determine the abundance and distribution of bird species and avian guilds. Woodland area better predicted bird species presence than woodland width. In addition, the probability of detection was positively correlated with woodland area for 11 bird species and negatively correlated with woodland area for eight species. A management simulation of woodland riparian corridor width indicated that current management suggestions were inadequate to provide habitat for a variety of Neotropical woodland migrant bird species. In the second aspect of my research, I examined the ability of two species of birds to supplement their habitat requirements by incorporating disjunct habitat patches on either side of a watercourse into a single territory. I found the probability of eastern wood-pewees (Contopus virens) crossing water gaps to reach simulated singing conspecific to be negatively associated with vegetation gap width. Red-eyed vireos (Vireo olivaceus) demonstrated no significant trend. However, the strength of red-eyed vireo vocal responses after crossing was inversely proportional to the width of waterway. These results suggest that species may differ in their response to simulated conspecific vocalization, and that water gaps less than 30 m wide may not hinder all avian species from crossing to reach playbacks, but may still curtail territorial responses. The third aspect of my work was to determine the ability of a species to colonize empty habitat patches. I simulated patch extinction events by removing Carolina chickadees (Poecile carolinensis) from woodland fragments. I found that chickadees arrived sooner in woodlots connected to other woodland by habitat corridors. I also found that individual chickadees were more often temporarily absent from smaller woodlots, suggesting that these birds utilized woodlots that insufficiently meet foraging and / or breeding requirements. And finally, although chickadees appeared in all woodlots at some point during the study, they were more likely to remain to breed in larger woodlots.
