A new study shows that rooks can cooperate with each other but they don't seem to understand the benefits.
Cooperation
A human can easily gauge when a helping hand is necessary, but what about a rook? Video footage from a recent study shows a precarious set-up where birds had to work together if they wanted some dinner.
Researchers found that they needed little training in order to cooperate on the task. But it seems they did not fully understand that they could not complete the task alone. If one rook arrived before the other, it would attempt to get at the food, in vain.
