The Southern Bald Eagle (Haliaeetus leucocephalus leucocephalus) is a resident species in the state of Baja California Sur (Grinnell 1928), occurring mainly in coastal habitats. Nesting is now known only from Bahía Magdalena–Almejas on the west coast (Henny et al. 1993; Amador-Silva and Guzmán-Poo 1994; Rodríguez-Estrella et al. 1995), where no more than three pairs are found annually.
The physiography of Baja California Sur is composed of extensive plains and hills. The principal mountain ranges are the Sierras la Giganta and la Laguna, and the predominant vegetation is desert scrub, which covers 92% of the state area (INEGI 1995). Freshwater habitats are scarce and largely temporary across the state.
