Can Crows Read?
Crows can recognise and ascribe numerical meaning to symbols, a new
study shows, suggesting that the unusually intelligent birds may be able
to “read” numbers and simple icons.
Crows are known for their extraordinarily good memories,
tool-making skills and ability to discern minute subtleties in judging a
threat level. It was reported earlier this year that the US military considered using crows to help track down al-Qaeda leader Osama bin Laden.
In the latest edition of the journal Animal Behaviour,
Japanese researchers describe an experiment in which eight jungle crows
were presented with two containers, one with “2” written on the lid and
one with “5”. The “5” container had food inside, while the “2” did not.
The crows soon learned to pick the “5” container at a 70% success rate. [the Conversation] link
