PHALAROPODIDAE Northern Phalarope (Lobipes lobatus): 15,093. All were along the coastal area from 20° to 28°N with maximum density at 25°N. Red Phalarope (Phalaropus fulicarius): 10. Observed along the cost only at 25°N, but many were probably overlooked in the large concentrations of Northern Phalaropes in other areas. STERCORARIIDAE Pomarine Jaeger (Stercorarius pomarinus): 15. 73 percent were dark-phase birds. All but one were within 300 miles of the coast. The exception was at 07°10'N by 111°24'W. LARIDAE Laughing Gull (Larus atricilla): #. Scattered birds were observed near and within the harbor at Manzanillo, Colima, Mexico. Western Gull (Larus occidentalis): 12. Observed only along the northern coast of Baja California from Cedros Island north. Heerman Gull (Larus heermanni): 26. Observed only along the northern coast of Baja California from Cedros Island north. Sabine Gull (Xema sabini): 32. Two, apparently migratory, flocks. One of 10 birds at ca. 28°N and one of 22 birds at ca. 17°N both near the coast. Swallow-tailed Gull (Creagrus furcatus): 1. In the colder water of the South Equatorial Current at 02°39'N by 097°34'W. This was just over 300 miles WNW of the Galapagos Archipelago. Forster Tern (Sterna forsteri): 4. Observed only along the coastal waters of Southern California and northern Baja California. Royal Tern (Thalasseus maximus): 45. Observed only along the coastal waters of Southern Baja California. Sooty Tern (Sterna fuscata): 546. Only 3 feeding flocks were found, all containing immature birds. One of 225 at 05.4°N by 112°W; one of 12 at 05.5°N by 111.6°W; and one of 300 at 18.6°N by 104.9°W. Scattered birds were recorded in areas near the above concentrations, and one bird each was recorded at 00°15"N by 104°39'W (an immature), and 01°26'N by 097°32'W (an adult). Common Noddy Tern (Anous stolidus): 2. Both were within 300 miles of Clipperton Island.
