Range.--Pacific coast from Lower California southward. This Gannet replaces the common Booby on the Pacific coast. It nests abundantly on many islands in the Gulf of California, and in company with the blue-footed variety, on San Pedro Martir Island. They generally lay two eggs, placing them upon the bare rocks and surrounding them with a ring of sticks and seaweed to keep them in place. The eggs are chalky white and cannot be distinguished from those of the other Boobies. Data.--San Benedicto Is., Lower California, May 18, 1897. Single egg laid on the sand amid a few blades of grass. 116. RED-FOOTED BOOBY. _Sula piscator._ This is another species that is only occasionally taken on the Florida coast. The habits of the birds and their nesting habits are the same as those of the others of the family. Two chalky white eggs are laid. Data.--San Benedicto Is., Lower California, May 18, 1897. Single egg. Nest a few twigs of rank grass. Collector, A. W. Anthony. [Illustration 077: Chalky bluish white, nest stained.] [Illustration: Booby.

These are the largest of the family, being 35 inches in length. They feed on fish which they catch by diving upon, from the air. When flying their neck is carried fully extended. They rest on the water when tired, the numerous air cells beneath the skin, causing them to sit high up in the water and enabling them to weather the severest storm in perfect safety. The only known breeding place in America is Bird Rocks, where they nest by thousands, placing their nests in rows on the narrow ledges; the nests are made of piles of seaweed, mud and stones. They lay but one egg of dingy white color and covered with a chalky deposit. On St. Kilda Island, off the coast of Scotland, they breed by millions. They are very tame and will frequently allow themselves to be touched with the hand. It is said that thousands of the young are killed by fishermen every year and marketed in Edinburg and other places. Data.--St. Kilda Island, Scotland, June 18, 1896. Single egg laid on a large mass of seaweed on a sea cliff. Collector, H. McDonald.
