These changes have brought about a dramatic change in the nature of breeding bird communities on the study areas and, likely, throughout Illinois. Neotropical migrants formerly accounted for over 70% of the breeding birds. Now they account for less than 50%—even on large woodlots. On small woodlots, like Trelease Woods, the problem appears extreme because the migrants account for only 25% of all resident birds. In summary the analyses indicate that few, if any, species have been lost during the 20th century, but that a large group of species may be in trouble. If trends persist, one-third to one-half the species typical of Illinois' forests may disappear fro
