some are known to remain throughout the summer. Mr. Swarth 

 tells me that this specimen had lost the power of flight during its 

 molt. He thinks this seems to indicate that Loons lose the ability 

 to fly during molting, as do the Anseres. 



Gavia pacifica (Lawrence.) Pacific Loon 

 June 27, I found a dead Pacific Loon cast up on the beach. The 

 specimen was in very worn and oddly colored plumage. On exam- 

 ination Mr. Swarth said it was a partial albino and had skipped a 

 regular molt. 



Lartis heennauni Cassin. Heermann Gull 

 Abundant about the Bay at Balboa. 



Mergiis serrator Linn. Red-breasted Merganser 

 A female taken July 6, 1914. This is a very late record for this 

 bird, since it leaves mostly in April. It was found resting on a 

 sand spit in Balboa Bay. 



Oidemia perspicillata (Linn.) Surf Scoter 

 Common along the coast from Laguna to Balboa. 



Oidemia deglandi Bonaparte. White-winged Scoter 

 Occurring with the preceding species. 



Erismatura jamaiceitsis (Gmelin). Ruddy Duck 

 Occurring at the tule lake in Laguna Canyon. 



Himantopiis mexicantts (Miiller). Black-necked Stilt 

 One taken at Laguna Lakes, now mounted and in possession of 

 J. N. Isch, Laguna Beach. 



Macrorhaviphus griseus scolopaceiis (Say) 

 Long-billed Dowitcher 

 A specimen taken on the sand spits in Balboa Bay, July 6, 1914. 

 This appears to be an early fall migration record. 



Catoptrophorus semipalmatus inornatus (Brewster) 

 Western Willet. 

 Abundant in August, less common in July. Often in company 

 with Hudsonian curlews {Numenius hudsonicus) along the coast. 

 One taken as early as July 6.
