Black vultures have been noted to nest nearby predatory raptors in Argentina, with one instance involving vultures and Chaco eagles, and another featuring vultures alongside barn owls. In the initial case, in La Pampa, a vulture was spotted close to a Chaco eagle’s nest shortly before the eagle’s egg went missing, which raised concerns about scavenging behavior. Both nesting attempts there were unsuccessful. In the subsequent case, in Santa Fe, both avian species were able to successfully raise their young even though they nested separately in a water tank. These observations, published in the Journal of Raptor Research by Diego Gallego-García and associates, underscore the vultures’ utilization of abandoned structures for nesting, likely due to a lack of other suitable sites. The authors propose that such proximity may confer protective advantages or may signify ecological traps in altered human landscapes.
