Away from the wolf, into the falcon.

In Brazil's Emas National Park, the maned wolf prowls the savannas and grasslands for birds and other small game. Overhead, the aplomado falcon searches for some of the same prey. Leandro Silveira and other park researchers noticed that the falcon often trails the wolf on its hunts, nabbing about 25 percent of the prey that gets away from the wolf. The researchers report their observation in the recently released February issue of The Condor.

The birds' association with wolves is new to researchers but not too surprising, says Stanley A. Temple, a falconer and wildlife ecologist at the University of Wisconsin-Madison. Other hunting associations exist between birds and monkeys, even sea birds and dolphins. "Birds of prey learn very quickly that other animals can flush prey for them," says Temple. Even human hunters can provide a tip-off, he adds.
