There is no accounting for what birds do. It is the custom, almost universal, in birddom to mate and breed in the spring of the year. Even in the tropics this holds good. The pelicans of the Gulf of Mexico breed in April, yet those of the East Coast begin their mating and flock to the single rookery, which is the nesting place of all East Coast pelicans, in November. Just below the twenty-eighth parallel of latitude there is in a sheltered bay in the Indian River a low, sandy island about three acres in extent. Here all East Coast pelicans breed, and have done so since man has known the Indian River. The pioneer birds who first chose this island chose wisely. The place is as far north as they dare breed for fear of cold, which would kill the young birds. These are born naked and for the first few weeks of their existence die of cold even under ordinary temperature, if left unbrooded over fifteen minutes. Hence one or the other of the parent birds keeps the nest during that time. On the other hand, they wish to be as far north as they can for two reasons. One is that excessive heat kills the unprotected young as well as cold. Another is that the menhaden fishing is better up the coast than down. Any fish is good enough for the palate of the adult pelican, but for some reason the birds prefer to feed their young almost entirely on menhaden. In October the breeding impulse comes to these East Coast birds and the stubby, brown mane grows along the backs of their long necks. Then they collect together in flocks of hundreds, up and down the coast, and begin to draw in toward the old home spot. Not, however, until all the clan has gathered do they bear down upon the island and take possession, coming in a multitude in the night as our Northern migrants come to their breeding places. Thus the night herons which winter in this region come to their rookeries in the Massachusetts cedar swamps. On a day early last November there were no pelicans on Pelican Island. On another day the warden whose ceaseless vigilance protects these birds during the nesting season from the depredations of mankind estimated that there were seven thousand there. But not all these pelicans were in breeding plumage or were there to breed. At the close of old home week the white-necked birds seem in the main to have departed, probably to take up the lightsome joys of bachelor existence like my friend in the cove. The others began nest building and placed some fifteen hundred nests on the three acre island. Then indeed began a carnival of Pelican growing which lasts each year until late June has brought the longest days, before the last young bird is full grown and the island is once more deserted. In fact, last year, though the breeding was finished by the usual time, the birds did not wholly leave the island and its vicinity the year through, but hung about in considerable numbers.
