Crow Feeding and Tending Young

  • This video shows Northwestern Crows feeding their young at a nest in Juneau, Alaska.
  • Of interest is after being fed one of the youngsters raises its rear end and the parent takes or eats its poop.
  • What are some of the advantages of this type of behavior?
  • The young don't defecate in the nest or beside the nest.
  • This may help avoid contamination.
  • It might be less obvious for predators whereas the nest site with a bunch of whitish poop may be visible from some distance away.
  • I have read that the parents may receive some nourishment by eating their youngsters poop.
