Last week the municipality of Jeddah with the ministry’s help began a crow-abatement program. The problem is that the crafty creatures aren’t falling for the traps. City workers are claiming that the crows are simply not taking the bait.

Awad Al-Qahtani, a municipal health protection manager, speculated that the crows have observed other birds eating the poison and dying, and are simply learning to avoid the poison.

"The most likely alternative," Daniel Sol states, "is that big brains enhance the rate of evolutionary diversification by facilitating changes in behavior, which would place new selection pressures on populations and favor adaptive divergence." Thus, in species with high cognitive styles, behavior might be, along with environmental factors, a major driving force for evolution.

"We didn't have data on enough species to address this question conclusively," Deaner said. "But the human brain imaging data indicate that some correction for 'neural traffic maintenance' is probably needed. If it wasn't needed, then we would be stuck with some real puzzles, such as the fact that there are no consistent sex differences in IQ, yet men generally have larger brains. And, of course, elephants and whales possess larger brains than we do, yet it's hard for us to imagine that they are smarter than we are."
