<p>In a striking example of birds adapting to urban environments, researchers have identified some crows and magpies making nests using bird-repelling objects. Researchers have recovered some nests from trees in Rotterdam in the Netherlands and Antwerp in Belgium made up of metal spikes and strips which are often attached to buildings to deter birds from making nests on the structures.</p>

<p>This shocking revelation led the scientists to further look for more such nests on the internet, and they managed to find two more, one in Enschede in the Netherlands and another in Glasgow.</p>

<p>“I didn’t expect this. These anti-bird spikes are meant to deter birds, they are supposed to scare them off, but on the contrary, the birds just utilise them,” Kees Moeliker, the director of the Natural History Museum Rotterdam, was quoted as saying by the Guardian.</p>

<h2><strong>Striking irony</strong></h2>

<p>Researchers noted that while crows used the metal spikes merely as a construction material, magpies went a step further. Magpies installed those metal spikes at the roof of their nests to prevent predators from settling in there.</p>
