Called “feathered apes” for their simianlike smarts, crows use tools, understand physics, and recognize themselves and humans. But new research suggests that the brainy birds may be even smarter than was previously thought. Given a complex problem and an assortment of tools, New Caledonian crows came up with a creative solution that hints at higher-order thinking. (See link.)
Intelligent animals both, crows and wolves have been known to play together in the wild and it has been observed that crows will sometimes alert wolves to potential prey in order that they might share in the food it would provide.
