Crows and magpies are utilizing anti-bird spikes to construct their nests, examine finds 

Roof spikes have lengthy been utilized by people to maintain birds at bay.

However evidently crows and magpies aren’t so scared in any respect, having stolen numerous sharp steel items to construct their very own fortified nests.

Consultants on the Netherlands‘ Naturalis Biodiversity Middle and the Pure Historical past Museum of Rotterdam made the stunning discovery that birds make use of roof spikes to scare off predators.

Their analysis unexpectedly took off at a hospital courtyard in Antwerp, Belgium, the place onlookers noticed a fowl’s nest made up of 1,500 steel spikes.

It stays unclear how the birds pay money for the spikes with out getting damage, though MailOnline has contacted the researchers for additional info.

‘An impregnable fortress,’ Auke-Florian Hiemstra of Naturalis mentioned. ‘As a result of the magpies look like utilizing the pins precisely the identical means we do: to maintain different birds away from their nest.’

This Eurasian magpie’s nest was under no circumstances the one instance of this, with others already seen in Glasgow and Enschede within the Netherlands.

Carrion crows additionally exhibited related behaviours close to Rotterdam’s Central Station, inserting an array of spiky objects in a weeping willow tree.

Whereas crows have been seen to make use of these sharp objects as a nesting materials, magpies appeared to put spikes in a means that overarched their ‘dome’ nests.

This means that magpies primarily use spikes for the practical objective of scaring off weasels and different birds. 

Barbed wire and even knitting needles have been amongst objects utilized by magpies too, in a solution to defend their nest roofs.

Even condoms and fireworks are ceaselessly encountered by Mr Hiemstra, alongside cocaine wraps, sun shades and even windshield wipers.  

‘It is like a joke, actually,’ Mr Hiemstra continued. ‘Even for me as a nest researcher, these are the craziest fowl nests I’ve ever seen.’

Kees Moeliker, director of the museum, added: ‘Simply once you suppose you’ve got seen all of it after half a century of finding out pure historical past, these ingenious crows and magpies actually shock me once more.’ 

Antwerp’s magpie nest is now on show on the Stay Science room of Naturalis in Leiden.

Whereas birds’ lack of concern in direction of spikes isn’t a brand new idea, consultants declare theirs is the primary scientific publication to place this into phrases.

This additionally comes simply days after a gaggle of European scientists discovered that 176 fowl species have been utilizing human-made supplies to construct nests.

This examine, led by the College of Warsaw, noticed that litter amassing behaviour was notably widespread amongst gulls, geese and lots of birds of prey in all continents however Antarctica.

‘Many birds, together with birds of prey, gulls and pigeons, are urban-adapted and breed efficiently in cityscapes the place human-made supplies are available,’ the workforce wrote in The Conversation.

‘The extent to which birds adapt to polluted environments stays underappreciated as a result of a examine like ours is just pretty much as good because the accessible information.’
