If you take a look around cities, you’ll likely find them in numerous structures. Anti-bird spikes are put to frighten birds and avoid them from building nests in metropolitan locations. But it appears some birds are not daunted at all.
Nests recuperated by scientists from trees in cities in Europe were discovered to be constructed from great deals of strips of the anti-bird spikes.
It all began with the discovery of a huge nest in Antwerp, Belgium, in the yard of a healthcare facility, which was initially seen by a client. Up in the tree, magpies had actually constructed a nest from a shocking 1,500 pieces of metal spikes. Auke-Florian Hiemstra, the research study lead author, explained it as an “impregnable fortress” as birds utilize the pins the exact same method people do -– to keep other birds away.
The nest’s discovery led Hiemstra and his group to search the web for more examples. Overall, this is the very first well-documented research study that argues birds are utilizing sharp spikes outwards to optimize their security.
“It’s like a joke, truly. Even for me as a nest scientist, these are the craziest bird nests I’ve ever seen,” Hiemstra included.
Adapting to city life
Magpies are understood to build a roofing system on their nests to safeguard their eggs and young. In nature, they actively look for tough plants, making use of spiky branches to prevent prospective egg burglars. However, in metropolitan environments, magpies found anti-bird spikes as another option to keep other meddlesome birds at bay.
Bird nests made from anti-bird spikes! 🤯 Even for me as a nest scientist, these are the craziest bird nests I’ve ever seen. Today my paper came out on this defiant behaviour. And it resembles informing a joke…

The research study explains many circumstances of magpie nests including anti-bird spikes. Remarkably, this phenomenon has actually been observed in the Netherlands, Belgium, and Scotland. Magpies were likewise discovered to utilize other sharp products such as barbed wire and knitting needles to build the roofing systems of their nests.
“Just when you believe you have actually seen it all after half a century of studying nature, these innovative crows and magpies truly amaze me once again,” Kees Moeliker, director of the Natural History Museum Rotterdam and co-author of the research study, said in a news release.
In the past, birds were discovered to include metropolitan products on numerous celebrations. Back in 1933, a museum in South Africa reported a crow’s nest constructed from copper, iron and barbed wire. More just recently, the viral videos of the “Parkdale Pigeon” and of other defiant birds acquired popularity on social networks for not being frightened by anti-bird spikes.
Hiemstra is now doing a Ph.D. at Leiden University on using synthetic products in animal structures. He has actually released previous documents on how birds utilize plastic plants to build their nest, as he describes in this interview with ZME Science. He has actually likewise discovered prophylactics, sunglasses, windscreen wipers and even drug covers utilized as nesting products.
The magpie’s nest found in Antwerp can now be viewed as a brand-new emphasize at the Naturalis Biodiversity Center in Leiden, Netherlands.
“If even bird-repellent sharp spikes are used as nesting material, apparently anything can end up in a bird’s nest these days. It doesn’t get any crazier than this, does it?” Hiemstra included a declaration.
The research study was released in the Journal of the Natural History Museum in Rotterdam.
