Wyoming Birds. - 25 



40. Rissa tridactyla tridactyla: Kittiwake! 



''Accidental and very rare. The Wyoming record is based 

 upon a single specimen taken at Douglas by Dr. Jesurun, 

 November IS, 1898. This bird has also been taken in Colorado 

 and occasional stragglers may be looked for.'' (Knight.) 



51. Larus argentatus: Herring- Gull. 



Apparently increasing in numbers. Reported by Mr. Rich- 

 ard as being a common summer resident at Yellowstone 

 Lake and in Big Horn Basin. There is a specimen in Chey- 

 enne which is said to have been taken on a lake near there. 



53. Larus californicus: California Gull. 



Mr. Lockwood reports several from the Laramie Plains. 

 Breeds on Yellowstone Lake. See Skinner. 



54. Larus delawarensis: Ring-billed Gull. 



Abundant summer resident on the Laramie Plains, and in 

 the northern portion of the state. Probably occurs over al- 

 most the entire state. 



55. Larus brachyrhynchus: Short-billed Gull. 



Exceedingly rare. Mr. Lockwood reports it from the Lar- 

 amie Plains. 



59. Larus franklini: Franklin's Gull. 



One was taken May 6th, ■ 1912, near, Wheatland, Wyoming.

60. Larus Philadelphia: Bonaparte's Gull. 



In addition to Knight's records in regard to this bird, it has 

 been reported only by Metz, from Sheridan. 



62. Xema sabini: Sa'bine's Gull. 



Two birds have been taken from the Laramie Plains. See 

 Lockwood;- 



69. Sterna forsteri: Forsfer's Tern. 



"Migratory; rare. Apparently a rare bird in Wyoming; 

 and has been reported 'only from the southeastern corner 

 of the state. Mr. Bond reports it from Cheyenne and Dr. 

 Jesurun from Douglas. I would naturally expect to find 

 this species as a summer resident." (Knight.)
