Einstein Corvidae – Crows & Ravens



Smart birds—crows, and ravens are part of the Corvid family. This group of perching birds includes blue jays, magpies, and nutcrackers.

In Old Norse and English cultures, a dark-haired person who steals is referred to as a ‘raven.’ Native Americans associated the raven with prophecy and an omen of loss.

Corvid Commonalities

As adaptable as the raccoon and coyote, corvids live in a variety of environments – wherever there’s a ready food source – and take full advantage of abundant opportunities that humans offer.

  • Omnivores – corvids will eat just about anything; insects, snails, worms, frogs, snakes, garbage, carrion, seeds, grain, berries and other fruit, fish, small turtles, crayfish, mice, and baby birds from other species.
  • They quickly learn how to access food sources whether it’s by opening trash cans or dropping nuts from distance.
  • Corvids are social animals, mating for life and living in extended family groups.
  • Males and females build nests together. Between 3 – 9 eggs are laid and chicks hatch after about two weeks. Older siblings help care for the young.
  • Family units provide education, protection, comfort, socialization, and companionship.

  • Thought to be one of the most intelligent birds, experts say their reasoning abilities are about the same as a seven-year-old child.
  • Crows remember events for ten years plus, teaching new generations what they learned.
  • Crows and ravens work in groups to problem solve.
  • Corvids have developed, sophisticated language skills – differing group and family dialects.
  • Mobbing is when they work together to drive off predators.
  • Corvids enjoy playing and require lots of mental stimulation.
  • They notice when a member of their group has died, holding ‘funerals.’
