De Benedictis 1964 March 16 on board "Golden Bean", Coros Is. to San Diego, Calif. fish at all; after breakfast saw 3-4 large gulls and 20+ Bonaparte's Gulls, the latter going N in a loose flock, nothing else. Didn't see anything else except the few gulls following the ship off to this time. Took out the last of the Coros Birds to skin. I discovered I had 2 not than I thought - gave one to Kristen to skin and prepared the rest myself. A ? in partial black plumage had the skull unossified except along the sutures; all the rest had all of the skull, except an area near the parietal margin, as follows Several showed signs of moulting along the head and neck region and in the central retinas. The stomachs of # 384 + 385 both contained grit and unidentifiable seed remains fully ground up. The two birds prepared as skeletons were a young ? with yellow bill + ? like plumage and an ad. male with full black plumage. (# 390-391). Saved one birds as an alcoholic specimen. They have the nice long feathers of the other geospines and are easy to skin. Their fat is along all feather tracks, especially at the vent and by the base of the neck, and is bright yellow in color. Some have much interperitoneal fat on the belly. The ?s with large gonads had firm, white testis; the ?s all had small ovaries, no brood patch and did not seem to be breeding birds at this time.
