Annual survival of an endangered passerine, the Florida Grasshopper Sparrow

Perkins and Vickery sought to determine annual survivorship for adult male and juvenile Florida grasshopper sparrows, a federally endangered taxon whose range is limited to central Florida. We captured, banded, and resighted 161 birds at two study sites, Avon Park Air Force Range and Three Lakes Wildlife Management Area, from 1995 to 1998.
