Ravens discover baits flying singly or in pairs, but after a bait is discovered they usually arrive in groups. In contrast, the maximum number of blue jays and crows eventually attending a bait is close to those discovering it. Unlike in crows and jays, two patterns of bait use are seen in ravens: baits are… CONTINUE READING
