232. Macrorhampus scotopaceus. IvOng-billed Dowitcher. 
Migratory; not uncommon. Probably occurs throughout 
the lower regions of the State, though all the records are con- 
fined to the plains region east of the mountains. It is not un- 
common there in migration, passing through about the middle of 
April. Breeds far north, but a record of one taken by H. W. 
Henshaw at Denver, July 24, 1873, would lead one to suspect 
that it may yet be found breeding in the State. 
233. Micropalama himantopus. Stilt Sandpiper. 
Migratory; rare. Only found on the plains of eastern 
Colorado where it is occasionally met in spring migration in 
May and early June and less commonly in the fall. It has been 
reported by Capt. P. M. Thorne, from Fort Lyon, where he 
killed a female May 22, 1883, with the largest egg the size of 
No. 6 shot (Auk, IV. .1887, 264), by Prof. Wm. Osburn, from 
Loveland, by F. Bond, from Cheyenne, and by H. G. Smith, 
from near Denver. Breeds north of the United States. 
239. Tringa maculata. Pectoral Sandpiper. 
Migratory; common. Occurs throughout the State in 
migration, both on the plains and even up to 13,000 feet in the 
mountains (Morrison O. & O. XIII. 1888, 107), though of 
course less common at the higher altitudes. Breeds in the Arc- 
tic regions. 
240. Tringa fuscicollis. White-rumped Sandpiper. 
Migratory ; not uncommon. A bird of the plains finding 
its western limit at the bage of the Rockies. It has been 
reported by Thorne, Breninger and Osburn. Breeds far north. 
241. Tringa bairdii. Baird’s Sandpiper. 
Migratory ; abundant. In fall migration this is one of the 
commonest of the Sandpipers, and is also common in spring. 
Breeds far north but returns early, entering the State again in 
the latter part of August. When moving northward it is a bird 
of the plains and the parks below 7,000 feet, but Trippe, Drew 
and Morrison agree that after the breeding season is over in 
August and September, it roams to the tops of the loftiest 
peaks, 13,000 to 14,000 feet, feeding on grasshoppers. Passes 
through during April and the first half of May. 
242. Tringa minutilla. Least vSandpiper. 
Migratory ; common. Arrives the latter part of April and 
is mostly gone by the middle of May. Is found principally 
on the plains and below 7,000 feel in the mountains.
