Some birds have been spotted using anti-bird spikes to construct their nests, turning the tables on their intended purpose. A recent study led by biologist Auke-Florian Hiemstra and his team at the Naturalis Biodiversity Center in Leiden, Netherlands, has shed light on this fascinating behavior, highlighting how Eurasian magpies (Pica pica) repurpose the sharp cto ward off other birds and safeguard their nests
Despite the potential benefits, the scientists warn we must remember anthropogenic material can be harmful to birds and reduce the amount we chuck out.
