Abstract
In the 1970s research, management, and recovery projects were initiated in Arizona and across the contiguous United States to address population declines and losses of Bald Eagles (Haliaeetus leucocephalus). The species has recovered nationally and was removed from the Endangered Species List in 2007. In Arizona, the Bald Eagle population is currently increasing with the potential to continue growing. Productivity has been relatively high for more than a decade, and breeding areas are being discovered in new areas and habitats.

In 2017 there were 85 known Bald Eagle breeding areas (nesting territories) in Arizona, and 65 were occupied by eagle pairs. By comparison, Florida alone has approximately 1,500 breeding pairs (Bald Eagle general information 2017). Bald Eagles breeding in Arizona are relatively isolated from neighboring populations due to long distances separating them, short natal dispersal distances, and little evidence of immigration or emigration. The small number of breeding pairs and relative isolation have made it necessary to continue intensive monitoring and management of the species in Arizona.
