Non-leucistic aberrations in the plumage of birds from Nayarit, Mexico

Huitzil, 2018
Abnormalities in the plumage are caused by multiple environmental and genetic factors. Plumage aberrations have been reported in Mexico, but all have been classified as leucistic (white color due to a recessive gene).

Landscape transformations produce favorable roosting conditions for turkey vultures and black vultures

Scientific Reports, 2021
Recent increases in turkey vulture (Cathartes aura) and black vulture (Coragyps atratus) populations in North America have been attributed in part to their success adapting to human-modified landscapes.

Effects of habitat and time of day on flock size of Turkey Vultures in Cuba (Cathartes aura)

ZooKeys, 2018
In agricultural landscapes, the Turkey Vulture Cathartes aura feeds mainly on carcases of domestic animals. In spring 2017, data on 214 flocks of Turkey vultures were collected in a road survey in Cuba (in total 2384 km). Turkey Vultures were found to be
