Hard times bring out the best in idle birds.
Corvid cleverness is making news lately. Two of my favorite science writers, Sharon Begley and James Gorman, describe a variety of experiments--reported in PLOS One by researchers in New Zealand–in which crows mimic the hero of Aesop’s ancient fable “The Crow and the Pitcher.” By dropping objects into containers of water, crows raise the water’s [...]
