As we learn more about the intelligence of crows, we can at least say with some certainty that it would be wise to avoid angering one. Overall, the study may eliminate the layered cerebral cortex as a requirement for higher intelligence. Among the busy areas in the crows’ brains during this phase of the sequence was, not surprisingly, the pallium. Nieder’s interpretation of this sequence is that Ozzie or Glenn had to see or not see a flash, deliberately note that there had or hadn’t been a flash - exhibiting self-awareness of what had just been experienced - and then, in a few moments, connect that recollection to their knowledge of the current rule key before pecking the correct target.ĭuring those few moments after the sensory neuron activity had died down, Nieder reported activity among a large population of neurons as the crows put the pieces together preparing to report what they’d seen. Crows are extremely versatile and will eat all kinds of things including small fish, amphibians, reptiles, mammals, the eggs and chicks of other birds, insects, worms, mollusks, seeds, nuts, grains, and fruit. Along the Atlantic coast it is, I believe, rarely seen farther east than Maryland. When there was no flash, no firing of the sensory neurons was observed before the crow paused to figure out the correct target. Black Vulture, or Carrion Crow This bird is a constant resident in all our southern States, extends far up the Mississippi, and continues the whole year in Kentucky, Indiana, Illinois, and even in the State of Ohio as far as Cincinnati. ![]() When Ozzie or Glenn saw a flash, sensory neurons fired and then stopped as the bird worked out which target to peck. ![]() In each test, they had to take the entire process from the top, seeing a flash or no flash, and then figuring out which target to peck.Īs all this occurred, the researchers monitored their neuronal activity. This sequence prevented the crows from simply rehearsing their response on auto-pilot, so to speak.
