The only way to prevent a repetition of this is to have a warden constantlyon the ground from June until the birds are through nesting. Of course,owing to the great abundance of the Petrels on St. Lazaria, the destructionof approximately five hundred incubating birds and their eggs would notseriously affect the numbers of the species, but if the nimibers of the visitingbears were to be materially increased the effect would be much more REMAINS OF TUFTED PUFFINS AND YOUNG GLAUCOUS-WINGED GULLS IN NEST OF NORTHERN BALD EAGLE. ST. LAZARIA BIRD-RESERVATION, ALASKA Photographed by Special Agent G. Willett As to the Crows that inhabit the island, I can find but little to say in theirfavor. They are always on hand to steal the eggs and young of the lucklessCormorants, and I have even seen them go into the caves and raid the Murrecolony. Practically none of the Cormorants nests contained complete setsof eggs or young, and the ground under the favorite roosting-places of theCrow was covered with shells of Cormorant eggs. It would seem that the exter-mination of these pests each year at the beginning of the nesting-season, anda continual campaign against others that might put in an appearance whilethe birds were nesting, would be the only feasible way to put an end to theirthievery.
