Crows and Magpies Use Anti-Bird Spikes in Nest Building: A Rebellious Act of Nature

Common anti-bird spikes, designed to deter birds from buildings, are being ingeniously repurposed by crows and magpies as nesting material. A new study reveals these birds collect and integrate the spikes into their nests, even potentially using them as defense against other birds. Researchers found this behavior in several European cities, with one magpie nest containing approximately 1,500 visible spikes. This discovery not only highlights the remarkable adaptability and intelligence of birds but also prompts reflection on the balance between urban development and wildlife.
