Message: <blockquote data-quote="Himalaya" data-source="post: 1407988" data-attributes="member: 56069">There is an assumption that Peregrines dominate Ravens, which is wrong.  Ravens have been known to drive away Peregrines from nest sites.  Who benefits the more from this relationship?   If a Buzzard or Goshawk or an eagle ventured near the cliff where both Raven and Peregrine nested - do both birds mob it?  Do either the Ravens or Peregrines attack each others young?  Have they been known to become that aggressive that they ruin each others breeding for the year?If a Peregrine brings a Pigeon or other prey to the nest - do the Ravens try to steal it or even take any scraps?   If a Raven brought a small mammal or bird it had killed to the nest, do the Peregrines rob it?  What about Buzzards and Ravens - do they nest close and how do they interact?</blockquote>
