Crows remember human faces and hold grudges for years
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
Research at the University of Washington found that crows recognize individual human faces and remember them for at least five years. Crows that were captured (even gently) by researchers wearing masks would recognize those masks years later and dive-bomb the researchers on sight. They also recruit other crows to join the harassment — passing on the grudge. Crows have been observed bringing gifts (shiny objects, food) to humans who feed them regularly.
Most people assume complex social memory is uniquely human or limited to large mammals — birds holding multi-year grudges upends that assumption.
