Range. - Pacific coast breeding along the whole coast of the United States.

This species is found more abundantly on the Faral-lones than is the Farallone Cormorant. Like the other Cormorants breeding on these islands, these cling closely to their nests, for fear of being robbed by the Gulls, that are ever on the watch to steal either eggs or young. Their nesting habits and eggs are identical with those of the other species. Size 2.50 x 1.50. Data. - Bird Island, California, May 24, 1885. A very bulky nest of seaweed on the rocks. Collector, A. M. Ingersoll.
