numbers. When the island was clothed with the low mangrove trees nesting conditions were much safer. Then the young birds did not leave the nest until about to fly, and the newly hatched were therefore better protected from being devoured by the neighbors' children. Moreover, the habit of wandering from the nest on the ground makes it difficult for parents to surely find their own offspring when they come back with food. Any mother with a neck full of fish is good enough for the youngsters, hence when a cargo arrives they all rush for it indiscriminately and the real offspring is lucky if he gets the luncheon. But the worst thing about the ground nesting is an occasional high tide which comes, driven by northeast winds, and floods the low portion of the island, sweeping large numbers of eggs and helpless young to disaster.
The pelican mother lays three eggs, pure white, about three inches by two in diameter, being thus slightly smaller than those of the Canadian goose. If for any reason the eggs of the young birds are destroyed another litter is laid. Perhaps the frequent destruction of eggs or nestlings in the crowded communal life of the island accounts for the prolongation of the breeding season here. The eggs hatch in about four weeks, and it takes about ten weeks more for the young to acquire full flight plumage. Three and a half months
