Dec. 31 - New Caledonian crows are well-known for their
ability to use tools but new research, recorded on video, reveals the
impressive binocular overlap of the celebrated bird's vision which helps it
seek out food. Researchers from the British universities of Oxford, Birmingham,
and St Andrews got a bird's eye view of the crow at work by placing an
ophthalmoscope video camera inside a baited tube and studying how the corvid
uses its overlapping vision and straight bill to help it access larvae. Jim
Drury has more.
