Bird brains

This is a cool discovery:

Scientists have found that rooks – a member of the crow family – were able to figure out how to raise the water level in a laboratory container by dropping stones inside to retrieve a tasty worm floating on the surface.

The only other animal shown to be able to perform the same task is the orang-utan, which was able to grasp a floating peanut by spitting water into a tube. Scientists believe the demonstration shows that, in many respects, rooks and crows have comparable intelligence to primates when it comes to the use of tools.

This comes soon after a finding that crows can remember human faces as well as we can.

Smart birds.
