Turkey vultures (Cathartes aura) may not be beautiful, but they are certainly adaptable. A new study published in the Journal of Raptor Research, titled "Turkey Vulture Aggregations at a Water Barrier Provide Evidence of Later Migration and Increasing Population Size Over 25 Years," suggests that turkey vultures in western North America are increasing in number and delaying their migration departure date.
