They may look a bit like birds of a feather, but when crows and ravens flock together, havoc ensues. Researchers at the University of British Columbia blame crows for the animosity between the two bird species. In a study published in The Auk: Ornithological Advances on July 4, researcher Ben Freeman found that in 97 percent of interactions between crows and ravens, crows were the aggressive party. Teamwork, Freeman says, “gives crows the upper hand” against the larger ravens. Freeman argues that the highly sociable crows, working in small platoons of between two and five, are forcing ravens to remain in confined geographic territories across the United States.
