236 JOURNAT-, OF ENTOMOLOGY AND ZOOLOGY 



some are known to remnin 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. 



Gavhi pacific a (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. 



Lams heermanni Cassin. Heermann Gull 

 Abundant about the Bay at Balboa. 



Mcrgiis 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 perspiciUata (Linn.) Surf Scoter 

 Common along the coast from Laguna to Balboa. 



Oidemia degJandi Bonaparte. White-winged Scoter 

 Occurring with the preceding species. 



Erismatura jamaicensis (Gmelin). Ruddy Duck 

 Occurring at the tule lake in Laguna Canyon. 



Himantopiis mcxicauus (Miiller). Black-necked Stilt 

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

 J. N. Isch, Laguna Beach. 



Macrorhamphus griseus scolopaceus (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. 



Catoptrophoriis scmipalmatns iuoruatiis (Brewster) 

 Western Willet. 

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

 with Hudsonian curlews {Niimenius hudsouicus) along the coast. 

 One taken as early as July 6.
