A new study by researchers at the University of Washington indicate that crows may be cognitively advanced birds that actually learn from observing the dead, according to the New York Times.
The study, by the university's Kaeli N. Swift, records crow interactions at points when dead animals are introduced to areas where they are feeding.
Swift fed a flock of crows in the same spot and then had an assistant bring in a dead animal. The birds nearly always responded vigorously each time.
"If you've ever been dive-bombed by a crow, it's really terrifying," said Swift.
She and fellow researchers found that the birds exhibited distinct responses to the dead animals placed before them and concluded their actions were partially a way to protect themselves – their fear being an indication they were aware that danger might be lurking nearby.
The study was published by Science Direct.
Swift says that there are many popular tales and myths about crows – why they do what they do – and her study is an investigation into the possible truth behind the stories.
"Whenever I give a talk about crows, there's always someone who says, 'Well, what about this?' " said Dr. John Marzluff, a consultant to Swift and the study.
Dr. Marzluff has had lots of time to study the patterns and behavior of crows, more than 20 years, and he says that the birds can even distinguish faces to the point where they "never forget," according to separate article from the New York Times.
