Description
Summary:Conservation of migratory birds necessitates protecting suitable stopover habitat along migratory routes as well as destination habitats, especially near large geographic barriers such as the Gulf of Mexico. The Florida Keys (Keys) are an important stopover and breeding destination for migratory landbirds. We documented 47 migratory and 21 resident landbird species via point counts during March–May 2004 and 2005. As a group, species richness, species diversity, and the effective number of species of migratory landbirds, including several species of conservation concern, was significantly and positively associated with percent cover of tropical hardwood hammock, a threatened upland forest type. The collective resident landbird community in the Keys was negatively associated with native hammock cover, although species diversity of the resident community was positively associated with the proximity of native hammock and several resident species, including species of conservation concern, were commonly or predominantly associated with native hammock. Consequently, conservation of native hammock habitat in the Keys is an important conservation priority for migratory birds and several resident species of conservation concern.
