Sometimes it seems like you can catch a cold just from seeing a bird outside in the middle of winter. How does a coat of flimsy feathers keep sub-zero temperatures at bay?
We humans use our vision for many things, but it’s limited because it relies on the primary colors.
Some other animals, like birds, can see on the ultraviolet spectrum. A new camera developed by researchers at Lund University in Sweden lets us have a sense of how birds see the world.
Snowy owls, despite their white plumage that allows them to blend into their Arctic surroundings, are easily recognizable. They’re beloved as a symbol of winter and as a companion to Harry Potter.

Wrens aren’t our flashiest birds, but they more than make up for it with their big personalities. Small and brown, they rarely sit still, whether vigorously defending their nests and territories, pecking for food on the forest floor, or just incessantly chattering away. They’ll get into shouting matches and physical confrontations with interlopers, including much larger species and humans, and even destroy eggs of other birds. In other words, wrens don’t mess around.

Wild plants and animals are vanishing amid a storm of human-induced disasters, namely habitat loss, unsustainable hunting, invasive species, pollution and climate change.
