March, iSgS. Birds of the Pacific Slope of Los Angeles County. 



15 — 31a. Larus argentaius smithsonianus Coues. 

 American Herring Gull. 

 This species is frequent in winter along the coast. I found it in 

 small numbers in December, '97, at Catalina Island, and a specimen 

 was obtained. 



16 — 5J. Larus californicus L,awr. 



California Gull. 

 Common winter visitant along the coast. This species also fre- 

 quents the fresh water marshes back from the coast, feeding on dead 

 ducks at the sporting grounds, and I have even .seen it along the river 

 bottom near I,os Angeles. 



17 — 54.. Larus delawarensis Ord. 



Ring-billed Gull. 

 Tolerably common along the coast in midwinter. J. F. Tiling- 

 worth has a specimen taken at Long Beach, Dec. 20, '92, and I have 

 one taken at the same place, Dec. 4, '96. 



18 — -57. Larus heermanni Cass. 



Heern)ann's Gull. 

 Generalh' a common winter visitant along the coast. I have seen 

 it in spring as late as May 11 ('97), and in the fall by Sept. i ('97). 

 When the fishermen draw their seines along the beaches, clouds of 

 gulls are usually attracted and of these, this species generally forms 

 about one-fourth, while the Western Gull forms about one-half. The 

 greater part of our winter visitants among the Laridse are in immature 

 plumage, and consequently in most cases diflBcult to distinguish at a 

 distance. I suspect that a systematic slaughter of the swarms of gulls 

 attracted by the fishermen would result in the addition of several more 

 species to our list. But this would be a practice that is certainly rep- 

 rehensible in the extreme, although I understand it has been resorted 

 to, to a successful degree, by a "lover of birds" near San Francisco. 



19 — 60. Larus Philadelphia (Ord). 



Bonaparte's Gull. 

 Occasional winter visitant along the coast. I have an adult male 

 taken near Santa monica, Dec. 8, '89, by E. C. Thurber.. I saw a pair 

 in San Pedro Harbor on May 11, '97, and a single individual at the 

 same place, Jan. 30, '97. 



20 — 6£. Sterna maxiftia Bodd. 



Royal Tern. 

 More or less common throughout the year along the coast. Very 

 numerous in winter around Catalina Island. I do not know of its 

 breeding north of I^ower California. 



21 — 6g. Sterna forsteri Nutt. 



Forster's Tern. 

 Common spring and fall migrant; seen generally about the sloughs 

 and bays. I secured specimens at San Pedro, Sept. i, '97. H. A. 

 Gaylord saw several individuals at Alamitos Beach, Dec. 4, '96.
