290 Felger, Colorado Water Birds. [£g 



258a. Catoptrophorus semipalmata inornata. Western Willet. — 

 Migrant or summer resident. (April-Sept. 5.) I have notes on this 

 species covering the most of the summer and believe it will yet be found 

 breeding here. 



261. Bartramia longicauda. Bartramian Sandpiper. — Summer resi- 

 dent. (Latter part of April-Aug. 23.) In summer common locally. I 

 have never found this species to be what I would call abundant at any 

 time of the year in Colorado. I have not seen many of them along the 

 Barr Lake Chain, and in other localities I have found them in nocking 

 time in not large numbers. 



263. Actitis macularia. Spotted Sandpiper. — Summer resident. 

 (Third week in March-Sept. 21.) In summer, common; in migration, 

 very common. Cooke says, "a few remain until far into the winter, if 

 not through the winter." 



264. Numenius americanus. Long-billed Curlew. — Summer resi- 

 dent. (March 31-Oct. 22.) A common bird on the plains in suitable 

 localities. Common along the Barr Lake Chain. 



[265. Numenius hudsonicus. Hudsonian Curlew. — Migrant; rare 

 in near-by areas. (About May 1-?.) Cooke says, "All the records of 

 this Curlew in Colorado come from the plains region east of the mountains." 

 (Birds of Colo., p. 67.) Upon tins statement alone, it is placed here in the 

 hypothetical list.] 



270. Squatarola squatarola. Black-bellied Plover. — Migrant; not 

 uncommon locally. (Last week of March-latter part of May; Sept. 12- 

 Oct. 22.) They are present along the Barr Lake Chain at some time during 

 perhaps every migrating season, in numbers varying from one to twenty- 

 five or more. 



272. Charadrius dominicus. American Golden Plover. — Migrant; 

 uncommon. (Last week in March-?.) This species is only occasionally 

 seen along the Barr Lake Chain, it being not nearly so common, as far as 

 my experience goes, as the Black-bellied Plover. 



273. Oxyechus vociferus. Killdeer.— Summer resident or resident. 

 (Feb. 3-Dec. 31.) In summer and migration, abundant; in December and 

 February, rare. I can all but call it with certainty a resident, since I have 

 never noted it in January, but I am still hopeful of finding it all through 

 the winter about the warm springs down the Platte River, or at open water 

 elsewhere. 



274. ^Egialitis semipalmata. Semipalmated Plover. — Migrant; rare. 

 Although found in migration over the whole of North America tins is the 

 rarest of our plovers. It stops here only occasionally in its migratory 

 flight between its breeding grounds in the far North and its winter home in 

 Middle and South America. 



281. Podasocys montanus. Mountain Plover. — Summer resident; 

 common. (March 23-Oct. 12.) A common breeder on the plains. Have 

 found eggs to be advanced in incubation as early as May 14, and young 

 about a day out of the egg on June 23.
