"Avian Retribution: Birds Turn the Tables with Anti-Bird Spikes in Nests"
Birds in cities are using anti-bird spikes, originally designed to keep them away, as weapons around their nests to protect against pests. Dutch researchers have found evidence of birds positioning the sharp spikes outwards, creating a fortress-like structure. This is the first well-documented study showing birds using anti-bird spikes in this way. The adaptability and determination of birds to protect their nests demonstrate their remarkable ability to adapt to their environment. While it may be an annoyance for humans, the researchers see it as a "beautiful revenge" as birds use human-made materials to build nests and increase their population.
