Well I did, so I conducted a directed study in Biology with Dr. Robert Paul , with additional help from Dr. Ron Matson . My purpose was to test the crow's problem solving abilities, as well as see if they would show any signs of insight. Because their territory is the entire KSU campus, they're very used to people, consequently they're pretty easy to study compared to other populations that are less tame.
Crows are highly intelligent and are good at adapting to changing conditions.
Our crows utilize the playing fields for insect foods, road kill, and the trash you leave in the parking lots, student center and around the garbage cans. Like Crows are omnivorous which means they will eat just about anything. This is one of the reasons crows have been so successful as a species. And yes, they really love greasy foods. So, if you see them digging around they might be looking for previously cached food.
