Crows acquire food in inventive ways
Crows and jays are the brain boxes of the bird world, according to a Canadian scientist who has invented a method of measuring avian IQ.
The IQ scale is based on the number of novel feeding behaviours shown by birds in the wild.
The test's creator Dr Louis Lefebvre was surprised that parrots were not high in the pecking order - despite their relatively large brains.
The research was presented at a major science conference in Washington DC.
