Articles about 'crow'

Urban birds are less afraid of litter than their country cousins, according to a new study, which suggests they may learn that litter in cities is not dangerous. The research could help birds to adapt to urban settings better, helping them to survive increasing human encroachment on their habitats.

Researchers at the Universities of Cambridge and Queen Mary, University of London have found that rooks, a member of the crow family, are capable of using and making tools, modifying them to make them work and using two tools in a sequence. The results are published on-line this week in the journal Proceedings of the National Academy of Sciences.

Nicky Clayton, Professor of Comparative Cognition in the Department of Experimental Psychology, has thrown the doors wide open on animal cognition. Where once the idea would have been dismissed that animals can re-experience the past and plan for the future, her imaginative studies have shown this inherent cleverness in crows.
