BIRDS OF TROPIC SEAS

Years of carefully planned expeditions to tropical lands have resulted in these pictures of the habitats and private lives of such species of bird life as the Socorro sooty tern; the blue-footed, olive-footed, and Brewster boobies; the Galapagos albatross, famed in annals of ornithology for its courting dance; the red-billed tropic bird; flightless cormorants of Albermarle Island; man o'war birds; fork-tailed gulls; and hummingbirds.
