Forty-eighth supplement to the American ornithologists' Union Check-list of North American Birds

tion of the 7th edition of the Check-list of North American Birds (American Ornithologists’ Union [AOU] 1998). It summarizes decisions made by the AOU’s Committ ee on Classifi cation and Nomenclature—North America between 1 January and 31 December 2006. The Committ ee has continued to operate in the manner outlined in the 42nd Supplement (AOU 2000). Two new members were added to the committ ee in 2006— R. Terry Chesser and Irby J. Lovett e. Changes in this Supplement fall into the following categories: (1) two species are added because of splits in species already on the list (Anser serrirostris, Buteogallus gundlachii); (2) three species are added (two transferred from the Appendix) because of new distributional information (Oceanodroma hornbyi, Mesophoyx intermedia, Falco vespertinus); (3) the name of one species is changed because of a split from an extralimital species (Larus michahellis); (4) three generic names are changed, one because of a merger of genera (Spizastur into Spizaetus), two because of a splitt ing of genera (Megaceryle from Ceryle); (5) one English name is changed because of a split of the species (Anser fabalis) and (6) one species is added to the Appendix (Threskiornis aethiopicus). Further, one family (Cathartidae) is removed from the Order Ciconiiformes and returned provisionally to the Order Falconiformes, its traditional placement before 1998, although its true phylogenetic position remains uncertain.

The importance of the Chicago region and the “Chicago Wilderness” initiative for avian conservation

The Chicago region is a large, established metropolitan region, that may play a critical role for the conservation of breeding and migratory birds in midwestern North America. The region includes over 80,000 ha of protected lands that include some of the best remaining grassland, oak savanna, and marsh habitat in the state of Illinois. Because of its juxtaposition with Lake Michigan, the region serves as a significant stop-over site for spring and fall migrants that comprise a diverse group of terrestrial and aquatic species. Efforts to conserve and restore habitat for birds in the region are being coordinated by a partnership of over 60 public and private organizations known collectively as the “Chicago Wilderness.” These organizations have joined to protect, manage, and restore the habitats and biological communities of the region. Specific activities include ecological inventory, the creation of recovery plans for various types of biologically significant habitats, restoration research, education and outreach, and the identification of region-wide conservation priorities. The benefits of these activities for birds are promising. Studies conducted in lands managed by the forest preserve district of Cook County indicate that the breeding bird communities in the preserves are quite similar to those in the rural areas of Illinois. Moreover, estimated rates of parasitism by Brown-headed Cowbirds (Molothorus ater) are less than those observed in the more agricultural landscapes of the upper midwestern United States. Habitat protection in otherwise developed metropolitan areas may offer significant conservation opportunities in regions where natural habitat is scarce.
