In a remarkable discovery, researchers placed a trail camera inside an abandoned house in Argentina, capturing rare footage of Black Vultures and American Barn Owls nesting in close quarters. This video records unprecedented interactions between these birds of prey, traditionally fierce competitors for nesting spaces. The study, detailed in the Journal of Raptor Research, reveals how these species coexist in such proximity.
When Extraordinary Footage Captures Uncommon Cohabitation
Footage shows Black Vultures alongside Barn Owls, and later Chaco Eagles, raising their young just a few feet apart in the ruins. This unique cohabitation was observed despite the potential for competition, even as species typically compete for resources. As the BBC’s Discover Wildlife Magazine reports, this may be the first documented instance of black vultures nesting near predatory raptors.
A fascinating sequence captured the black vultures nesting adjacent to a pair of American Barn Owls inside a room of an abandoned house in northern Argentina. In another instance, rare scenes display vultures incubating two eggs while Chaco Eagles occupied a nearby hunting tower, tending to a single egg. Despite the proximity, there were no direct conflicts recorded in the shared spaces.
The footage provides a rare glimpse into the behavior of these species. Black Vultures, found throughout the Americas, are known for scavenging, and often nest in human-made structures. Their presence in abandoned sites has become increasingly common. In contrast, Chaco Eagles are hunters, primarily preying on mammals, which makes their nesting choice beside vultures particularly intriguing when such records show this behavior.
A notable moment caught by the trail camera occurred when a vulture was seen at the eagle’s nest while the adult eagle was absent, followed by the disappearance of the eagle’s egg. The researchers couldn’t confirm if the vulture was responsible, illustrating the complex dynamics at play in these abandoned spaces.
