[QUOTE="AStevenson, post: 1408697, member: 34537"] You should read Derek Ratcliffe's mongraph on the raven - has a whole section on peregrines and ravens sharing nesting cliffs. Despite all the aggression by both species, apparently losses of one to the other are rare. Peregrines do force ravens to abandon nests sometimes, and are recorded taking ravens particularly newly fledged juveniles. Ratcliffe lists 3 instances of ravens attacking peregrines - one was forced to the ground but was unhurt; one was badly injured; and the other killed. Ravens are recorded scavenging peregine prey items from plucking site near the nest, but there is little overlap on feeding - Ravens being crows tend to bring food balls in the their crop back to the nest to feed young. The earlier breeding of raven may well avoid serious confrontation with the peregrines. I'm fortunate to have ravens and buzzards nesting c200m apart within site of my house - haven't seen much really aggressive interaction, but they do both mob golden eagles. Cheers, Andrew [/QUOTE]
