As the vultures do not perspire like humans, the act of urinating on the legs helps to cool themselves in summer. At the same time, the strong acids of its urine kill bacteria on the legs.

Why do Turkey have bald heads?

How do turkey vultures defend themselves?

Why do vultures change their posture and posture?

By changing their posture to expose more or less of the bare skin on their heads and necks, vultures could cut their heat loss by half in cold conditions and increase their heat loss by almost a quarter in certain hot conditions. ‘That’s a really valuable energy saving for a scavenging bird that may spend many days without food,’ says McCafferty.

Much like their bald heads, their unfeathered feet and legs can also help vultures get rid of excess body heat. To aid that process, some species will literally poop on their legs and allow the viscous liquid to evaporate, cooling their skin.

As nature’s clean-up crew, vultures slow the spread of diseases—including those affecting livestock. And the birds help sustain plants by returning nutrients to the environment. When vulture populations decline, other scavenging animals won’t always pick up the slack.
