Bad reputation of crows demystified

23 enero 2015

In literature, crows and ravens are a bad omen and are associated with witches. Most people believe they steal, eat other birds’ eggs and reduce the populations of other birds. But a new study, which has brought together over 326 interactions between corvids and their prey, demonstrates that their notoriety is not entirely merited. The study analyzed the impact of six species of corvid on a total of 67 species of bird susceptible to being their prey, among which are game birds and passerine birds.
