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
