-8- Blue-footed Booby (Sula nebouxii) 25 This is a coastal species with all sightings along the Mexican mainland. Blue-faced Booby (Sula dactylatra) 3 The few birds sighted in equatorial current waters at remote distances from land could come from any of a number of origins. Brown Booby (Sula leucogaster brewsteri) 1019 Great numbers of this species were recorded along the Mexican mainland north of Manzanillo. On 31 March they were abundantly encountered with Laughing Gulls and lesser numbers of Sooty Terns feeding over small groups of sailfish. The white-headed adult males of this race are distinguishable. Red-footed Booby (Sula sula) 31 Most birds noted were dark plumaged immatures. Sightings ranged out to about 400 miles from the Mexican coast. One immature was collected over an oil slick. Frigatebirds 10 The few coastal sightings were presumed to represent the Magnificent Frigatebird (Fregata magnificens). One immature of as yet undetermined species was collected at 2°-30'N; 105°W on 4 March. The nearest land from this position is roughly 500 miles (Clipperton Island) and about 900 miles to the Galapagos Islands. Red Phalarope (Phalaropus fulicarius) 14 Northern Phalarope (Lobipes lobatus) 81 unidentified phalarope sp. 267 Phalaropes were found in large flocks along the Baja California coast and Mexican mainland and scattered small numbers were encountered throughout the entire cruise as far south as 20°S. I believe that the majority of sightings were of Red Phalaropes. Five specimens of this species were collected. One taken on 20 March was molting into the breeding plumage. Pomarine Jaeger (Stercorarius pomarinus) 37 Parasitic Jaeger (Stercorarius parasiticus) 3 Pomarines were common along the Mexican mainland coast and a few were encountered to 10°S. Most of these were in general areas of Sooty Tern concentrations. Two Parasitic Jaegers were recorded with a small group of Juan Fernandez Petrels at 12°S and another was sighted at 12°N. Gulls (Larus sp.) All gulls were recorded along coastal areas. Western and California Gulls were common along the Baja California coast and Laughing Gulls were most abundant along the Mexican mainland north of Manzanillo. One specimen each of Western and Laughing Gulls were collected.
