One of many nests in query, a Eurasian Magpie nest present in a hospital courtyard in Belgium, was found to include as many as 1,500 spikes including as much as about 50 meters of anti-bird spike strips.
What’s actually unbelievable about that is the truth that, not solely are these corvids overcoming human deterrents, they could even be utilizing them as supposed.
