66 BIRDS OF COLORADO. 



243a. Tringa alpina pacifica. Red-backed Sandpiper. 



Migratory; rare. There are but three Colorado records for 

 this species, which is found throughout North America. There 

 was an adult in winter plumage in Mrs. Maxwell's collection, 

 and Wm. G. Smith took it at Loveland, April 29 and May 9. 

 Breeds far north. 



246. Ereunetes pusillus. Semipalmated Sandpiper. 

 Migratory; not uncommon. Arrives the last of April and 



first of May. Mostly on the plains and below 7,000 feet. 



247. Ereunetes occidentalis. Western Sandpiper. 

 Migratory; rare. Should not be an uncommon species in 



Colorado, but so far has been reported but three times. Prof 

 Wm. Osburn writes that he shot one at Loveland, July 4, 1889, 

 and another May 12, 1890. W. P. Lowe, of Pueblo, shot two on 

 a lake near there in the fall of 1894. Wm. G. Smith took one 

 at Loveland, May 9, 1890. Breeds far north. 



248. Calidris arenaria. Sanderling. 



Migratory; rare. Though occurring over most of the 

 world, it is quite rare on the plains region of the United States. 

 Prof Wm, Osburn reports three captures at Loveland, Septem- 

 ber 24, 1889, September 30, 1889, and May 12, 1890. H. G. 

 Smith saw one May 16, 1888, that had been taken a few days 

 before at Sloan's Lake, near Denver. There is a mounted spec- 

 imen at the college at Fort Collins that was shot in the vicinity. 

 Breeds far north. 



249. Limosa fedoa. Marbled Godwit. 



Migratory; not common. A bird of the plains not often 

 seen; arrives about the first of May. Has once been taken in 

 the mountains by C. E. Aiken at the San Luis Lakes, October 

 I, 1874. Drew gives it as breeding on the plains, which it 

 does in Nebraska, but there seems to be no record as yet of its 

 nests being found in Colorado. 



254. Totanus melanoleucus. Greater Yellow-legs. 

 Migratory; common. Found both spring and fall every- 

 where in favorable localities below 7,000 feet. It is a little 

 strange that neither the Greater nor the Lesser Yellow-Legs is 

 know to breed in Colorado, since they both breed in Nebraska 

 but a few miles from the northeast corner of Colorado. They 

 reach northern Colorado about the first of April. 



255. Totanus flavipes. Yellow-legs. 



Migratory; common Distribution and migration the 

 same as that of the Greater Yellow- Legs but in most places not
