So much for throwing the term "bird brain" around as an insult. Pigeons are proving that they're no slouch in the intelligence department, especially when it comes to numerical competence.
A study published in the latest issue of the journal Science, reveals that pigeons have surprising math abilities, leading scientists to question whether they are unique in this regard in the bird world, or if all birds have greater intelligence than we typically assume. "It would be fair to say that, even among birds, pigeons are not thought to be the sharpest crayon in the box," lead author Damian Scarf told Discovery News. "I think that this ability may be widespread among birds. There is already clear evidence that it is widespread among primates."
