Pigeons aren't so bird-brained after all.
New research at the University of Iowa shows that pigeons can discriminate the abstract concepts of space and time -- and seem to use a different region of the brain than humans and primates to do so. In experiments, pigeons were shown on a computer screen a static horizontal line and had to judge its length or the amount of time it was visible to them. Pigeons judged longer lines to also have longer duration and judged lines longer in duration to also be longer in length.
