When we look at the way an object moves, humans are able to use this context to infer weight – whether it is light or heavy.

Now, New Caledonian crows have demonstrated the same skill – accurately gauging the weight of an object based on how it moves in a breeze.

They could be the first non-human animals known to have this ability, according to researchers from the University of Cambridge in the UK, the University of Auckland in New Zealand, the Max Planck Institute for the Science of Human History in Germany and Bertha von Suttner University in Austria.

Crows and ravens are pretty well known for their incredible smarts. In this experiment, psychologists sought to determine how well New Caledonian crows can infer weight.

“If we see one cardboard box blowing down the street in a breeze, and one remaining stationary despite gale force winds, we can infer which box is heavy and which is light,” the researchers wrote in their paper.
