Conflicts between rural people and the Endangered Black-and-chestnut Eagle (Spizaetus isidori) are a prominent conservation concern in the northern Andes, as at least 60 eagles were poached between 2000 and 2022 in response to poultry predation. Here, we conducted direct observations to analyze the Black-and-chestnut Eagle diet and evaluated how forest cover affects the feeding habits of the species during nestling-rearing periods in 16 nests located in different human-transformed Andean landscapes of Ecuador and Colombia. We analyzed 853 prey items (46 species) delivered to nestlings.

Article Synopsis
  • Vultures, including the Andean Condor, are among the most threatened bird species globally, with a declining population of about 6,700 mature individuals, particularly in northern South America where their numbers are critically low.
  • From 1979 to 2021, 164 Andean Condors were reported injured or killed, predominantly in Ecuador, with poisoning (103 cases) being the leading cause of mortality, alongside shootings and other factors.
  • Urgent measures such as environmental education, research, and better enforcement of conservation laws are needed to address human-induced threats and support the survival of the Andean Condor in the region.
