But where sheep have been introduced, the (roldenEagle may become more or less injurious through its acquired habit ofpreying on lambs. Four species of Eagles have been recorded from America north ofMexico. Of these the Gray Sea Eagle, an Old World species, is foundin this hemisphere only in Alaska; and the Harpy Eagle, a tropicalspecies, has bem recorded but once, from Texas.

There is nosoil or beach, and all the birds nest on the beds of matted Miles, usuallyat the border of the island. The White Pelicans, therefore, find here n<pebbles with which to construct their usual mound-like nests; the ( Cas-pian Terns do without sand, and the Cormorants without rocks. Farmore important than these is the protection which ground-nesting com-munal birds require, and this the islands supply. Fifteen colonies of White Pelicans were counted in this localitybetween June 30 and July 7, 1906, and doubtless there were others,since only a part
