Nurturing Nests Lift These Birds to a Higher Perch

Amid all the psychosocial caterwauling these days over the relative merits of tiger mothers and helicopter dads, allow me to make a pitch for the quietly dogged parenting style of the New Caledonian crow.

New Caledonian crows are renowned for their toolmaking skills.

In the complexity, fluidity and sophistication of their tool use, their ability to manipulate and bird-handle sticks, leaves, wires, strings and any other natural or artificial object they can find into the perfect device for fishing out food, or fishing out second-, third- or higher-order tools, the crows have no peers in the nonhuman vivarium, and that includes such textbook dexterous smarties as elephants, macaques and chimpanzees.

Videos of laboratory studies with the crows have gone viral, showing the birds doing things that look practically faked. In one famous example from Oxford University, a female named Betty methodically bends a straight piece of wire against the outside of a plastic cylinder to form the shape of a hook, which she then inserts into the plastic cylinder to extract a handled plug from the bottom as deftly as one might pull a stopper from a drain. Talking-cat videos just don’t stand a chance.
