KODACHROMES BY FREDERICKKENTTRUSLOW(ABOVE)ANDDR. FRANKLINB. PECK,SR. ( N.G.S. Dropping to his nest on wings spanning five feet, a male brings home a two-pound ladyfish from Florida Bay. Father-normally the family's sole provider at nest ing time-eats the fish head, leav ing the choice meat for his brood. If taken from an insecticide polluted area, fish may introduce poisons into the birds' bodies. The author, world-famed orni thologist Roger Tory Peterson, believes that this may be the rea son for egg failures in Connecti cut River eyries. Skyway robbery! As an osprey wings to its nest with a 1 1 /2-pound bonefish from the Gulf of Cali fornia, a frigate bird attacks. The osprey, left, swerves and loses its grip on the prize. Neck out stretched, the pirate jerks the fish away with its hooked bill. Such air battles between these two species rarely occur, since their summer ranges overlap only slightly; the more common high jacker is the osprey's powerful cousin, the bald eagle (page 66).
