The surprising key to magpie intelligence: it's not genetic

If you’ve ever had the pleasure of encountering Australia’s iconic magpies, you know these birds are intelligent creatures. With their striking black and white plumage, loud warbling voices and complex social behaviours, magpies possess a level of avian brilliance that fascinates birders and scientists alike.

But what enables these clever birds to thrive? Are their sharp cognitive abilities innate – something coded into their genetic makeup? Or are magpie smarts more a product of their environment and social experiences?

In a new study, we shed light on the “nature versus nurture” debate – at least when it comes to avian intelligence.

Bigger social groups, smarter birds
Our study focused on Western Australian magpies, which unlike their eastern counterparts live in large, cooperative social groups all year round. We put young fledglings – and their mothers – through a test of their learning abilities.

We made wooden “puzzle boards” with holes covered by different-coloured lids. For each bird, we hid a tasty food reward under the lid of one particular colour. We also tested each bird alone, so it couldn’t copy the answer from its friends.
