 Mar., 1908 NOTES I*ROM SAN CLEMENTE ISLAND 83 plumage, i.e. with white filaments along the sides of head, neck and back, were secured in February and March. Breeds in small numbers on the northwest coast. Phalacrocorax pelagicus resplendens. Baird Cormorant. A few pairs were seen near Mosquito Harbor, during March. These were in breeding plumage (white flank patches). One specimen in winter plumage, taken in October. Pelecanus californicus. California Brown Pelican. Frequently seen near northwest coast. Adults and immature specimens were secured. None were seen during late March. Aythya affinis. Lesser Scatlp Duck. Several ducks which I believe to be of this species, were seen during February. In October several thousand ducks, of several species, were reported off the northwest coast by fishermen. Ardea herodias. Great Blue Heron. Several pairs are resident on the Island. Heteractitis incanus. Wandering Tattler. During October and March, Tattlers were frequently observed feeding along the outlying rocks in the vicinity of 'Mos- quito Harbor and Smugglers' Cove. In all, sixteen specimens were preserved. Actitis macularia. Spotted Sandpiper. Fairly common on both coasts during fall and winter. JEgialitis nivosa. Snowy Plover. Flock of fifteen or twenty seen on the sandy beach, Smugglers', October 15. Arenaria melanocephala. Black Turnstone. Several seen near Smugglers' in October and April; twelve specimens were taken. Zenaidura macroura. Mourning Dove. Not uncommon in the vicinity of Smugglers'. A few seen, in March, near Mosquito Harbor; very shy during that month but later becoming quite tame, feeding in the grass near camp. Seen in October. Breeds. Buteo borealis calurus. Western Red-tail. Several pairs were nesting on the Island. Haliaetus leucocephalus. Bald Eagle. Found nesting in the larger canyons, one-fourth to one mile from the coast, during February, March and April. Sev- eral nests were visited and two fresh sets of two eggs each taken, February 15, and March 15. Scattered about the base of the cliffs in which the nests were situated, were numerous skeletons of sheep and young lambs. Falco peregrinus anatum. Duck Hawk. One pair seen near the northwest coast and another near Mosquito Harbor. One pair, at least, bred on the Island this year. Fako sparverius. Sparrow Hawk. These trim little falcons were occasionally seen hovering over the brushy mesas arid cacti-covered hillsides of the northeast coast, and inland. Only one specimen, a nmle, was secured. This differs some- what in general coloration from specimens taken in the coast district of the main- land, but the normal variation in the species is great. Pandion haHaetus carolinensis. American Osprey. During January and February a number were seen. In March they were observed remodeling old nests along the northeast coast and two fresh sets were found: March 9, one of three; March 31, one of three. On April 2, I visited a colony of twelve or fourteen n, ests on the southeast coast. Here, incubation ranged from fresh to two-thirds advanced. One set of four eggs was secured, and another found; one egg of the latter set had been crowded out of the nest onto the rocks and broken. Nests varied in size from a few sticks and pieces of sea-weed to immense piles of sticks and kelp four to six feet in hight by three to five feet in diameter, cavity of the largest being (diameter) twelve inches by (depth) four inches. The majority of nests were built on columns of rock standing directly in the surf.
