Cavity-nesting birds have an unusual way of deterring predators: lining their nests with snake skin, according to the Cornell Chronicle. Research shows this strategy is more common in birds that use covered nests with small openings than those with open-cup designs, significantly reducing predation risks.
Researchers tested this hypothesis by placing snake skins in various nests. Cavity nests with snake skin saw far fewer predator intrusions, mainly from flying squirrels. Open nests, however, showed no such benefit. Historical data from the late 1800s also supported the trend, emphasizing that this unique behavior evolved to protect eggs.
