Flipper. Flipper! FLIPPER!

Their social lives are complex, and they can congregate in large groups. Their heart rates increase when they notice a family member suffering. They sound the alarm when they discover food or a potential threat. And experiments have shown they even anticipate future events.

Biologist Justin Gregg is talking about chickens. Chickens, says Gregg, "are not as dim-witted as popular opinion would have us believe." He adds, "Some of these complex behaviors have also been observed in dolphins."
Really? Are chickens as smart as dolphins? Or, to put it differently: "Are dolphins really smart?" This is the question Gregg, a zoologist with the US-based Dolphin Communication Project, asks in his new book of the same name. And he isn't the only one finding fault with Flipper's brainpower.
