Naturalist Allan Octavian Hume noted in 1889 that dried snakeskin was commonly found in bird nests, leading him to question its function. Recent research, published in The American Naturalist, examined historical data and observed over 140 nests. The study concluded that nests adorned with snakeskin have a significantly lowered risk of predation. This insight suggests a practical purpose behind the peculiar use of snakeskin by birds, which raises further questions about how these birds locate and utilize such uncommon materials for nest protection.
A new study suggests that the presence of snakeskin in bird nests significantly reduces the risk of predation on the eggs, supporting Hume's 1889 hypothesis.
Researchers analyzed historical records and conducted observations, concluding that the macabre decorations, such as snakeskin, serve a real purpose in protecting eggs.
