2001 Robinson, Scott K. Chapa Vargas, Leonardo 2015-09-25T21:00:14Z 2015-09-25T21:00:14Z 10000-01-01 2001 I also tested the alternative hypothesis that vegetation structure and composition rather than fragmentation may influence nesting success and populations. I measured nest concealment, complexity and heterogeneity of vegetation in the vicinity of the nest, and the plant communities in which the nests were located. Acadian Flycatcher nesting success increased with increasing nest concealment. Although Acadian Flycatchers preferred to build their nests in certain tree species, tree species was unrelated to nest concealment and nesting success. Most of the other vegetation variables that were measured at the nest patch and habitat type did not influence nesting success. Local and landscape fragmentation effects appear to be the strongest correlates of nesting success of Acadian Flycatchers in Illinois, but other variables such as vegetation structure may account for the poor predictive power of these correlations.
