Dr. James V. Remsen Jr. of the Louisiana Museum of Natural Science suggested that we check the habitat and migratory status assignations for bird species we included in our article on changes in bird abundance in eastern North America (BioScience 57: 360–370). After further detailed examination of regional and other literature, out of the 330 species that were included in our study, we would change the assignation of migration latitude (for example, from “Mexico” to “Mesoamerica and northern South America”) for 15 species, and habitat choice (for example, from “edge” to “forest”) for 12 species.

We have reanalyzed the data, and we conclude that the changes make no substantial difference to the overall patterns we reported in our article. We retain full confidence in the conclusions. Corrected data and replotted graphs are available at
