Mr. Leverett M. Loomis well illustrates the habits of these birds in a report on the California Water birds. He says of a rookery “which is situated on a rock, or little islet, in the ocean at the extremity of Point Carmel, about fifteen yards from the mainland. This rock rises perpendicularly some forty or more feet above the water. At first sight it does not seem that it can be scaled, but closer inspection reveals that a foothold may be had in the seams and protuberances on its water-worn sides. Only on days when the sea is very calm can the rock be landed upon and then only from the sheltered channel separating it from the mainland. We first took a view of the rookery from the mainland. The Cormorants were very tame, remaining on their nests while we clambered down the sloping rocks and while we stood watching them on the same level, only a few yards away. They were equally tame when our boat drew nearer as we approached from the water. The clefts in the sides of the rock were occupied by Baird’s Cormorant and the top by Brandt’s. There were comparatively few of the former, but of the Brandt’s Cormorant there were upwards of two hundred pairs. Their nests covered the top of the rock, every available situation being occupied. Standing in one place I counted one hundred and eighteen.” He also states that the Cormorants remained on the nests till he fired his gun and they lingered on the edge of the rock while he walked among the nests a few yards away. On the rock were many piles of sardines, evidently placed near the nests for the use of the sitting bird. The nests are nearly circular when placed on top of the rocks, and are usually constructed of eel grass. They are generally placed in the most inaccessible places and at various heights above the surface of the water. The Cormorants frequent the same locality from year to year and experience considerable difficulty in constructing their nests because of the gulls which frequently carry away the material as fast as it can be gathered. The young, when first hatched, are entirely devoid of plumage and their skin resembles a “greasy, black kid glove.” It is said that the gulls feed upon these young birds. Mr. Frank M. Woodruff relates the following observations, made during a recent trip to California. He says:
