Ravens have intelligence. Indeed, lab studies demonstrate that ravens will cooperate on a project that requires two of them. If yesterday’s test is a measure, they regularly cooperate on a joint exercise in the wild. Mind you, it all happened prior to any observations, but the results seem obvious.
Two ravens had set on a mouse nest, and each then grabbed a victim. They were seen first when they flew off together to utility poles on opposite sides of the road to eat them.
On the north side of the road was seen a mouse whose head had already been eaten.
A closer view was obtained from the raven on the south side of the road.
The south-side raven was tossing fur around to get at the meat.
