A chickadee may have a bird-brain, but it can actually be pretty smart.
Especially if it lives in a harsh climate.
What does climate have to do with bird intelligence? As it turns out, more than you’d expect.
Biologists have discovered that chickadees living in the mountains or in northern latitudes, where the weather is more severe, were smarter than their peers living more comfortably down below.
Chickadees from harsher habitats had superior spatial memories and problem-solving abilities than those living in gentler climes. They were better at finding stored caches of food and at figuring out how to access a worm treat that scientists had cleverly tucked into a glass tube.
The harsh environment makes their brains work a bit harder.
Is there a lesson for humans in the example of the chickadees?
Yes, but it isn’t to move to a more wintry climate (take it from a Canadian who’s done her share of shovelling snow—it hasn’t made me smarter!).
The takeaway here is that there can be unseen benefits to the challenges we face.Read more
