THE NATIONAL GEOGRAPHIC MAGAZINE © National Geographic Society STRANGE ANIS AND SWIFT ROAD-RUNNER ARE CLOSE COUSINS All are members of the cuckoo clan, although they bear little resemblance to their relatives except for the long tail (see opposite Plate). The SMOOTH-BILLED ANI (upper left) and the GROOVE-HILLED ANI (right) are subtropical birds which barely come within the borders of the United States. Like cowbirds, they are often seen around cattle and feed on parasitic insects. The ROAD-RUNNER, swallowing a lizard, is a ground cuckoo which rivals a horse in fleetness.
