Frederick (in Naples, FL), here's the four species on the list (compiled via the National Audubon Society, 2007):

Golden-winged Warbler
Golden-cheeked Warbler (Endangered)
Kirtland’s Warbler (Endangered)
The U.S. WatchList reflects a comprehensive analysis of all the bird species in the United States, and identifies those in greatest need of immediate conserva- tion attention. The list builds on data from Partners in Flight (PIF), the latest research from the bird conservation community, and data from the Christmas Bird Count and Breeding Bird Survey.
Identifying and spotlighting the species at greatest risk is the first step in building the public policies, funding support, conservation initiatives, and public commitment needed to save them. The U.S. WatchList lays the groundwork for an “industry stan- dard” to guide conservation priorities among conservation organizations and government agencies.
