What unique sensory adaptation allows the Turkey Vulture (Cathartes aura) to locate fresh carcasses, often surpassing sight-reliant scavengers?
Answer
An excellent sense of smell
The Turkey Vulture (*Cathartes aura*) possesses a highly developed and acute sense of smell, which is virtually unparalleled among birds. This olfactory prowess is a crucial adaptation that allows this New World Vulture to successfully locate fresh carcasses, even when they are hidden from view beneath forest canopy or are otherwise missed by scavengers that rely solely on sight to locate food sources. This superior sense of smell directs them efficiently to their next meal across their broad habitat range.
