quite so numerous. Capt. Thorne shot one at Fort Fyon July 
23, which would indicate that it nested not far distant. 
256. Totanus solitarius. Solitary Sandpiper. 
Summer resident, not common; in migration, common. 
Occurs both on the plains and in the mountains. Arrives in 
April and most pass on to breed north of the United States, but 
a few remain to breed from the plains at the eastern base of the 
mountains up to 10,000 feet. 
258a. Symphemia semipalmata inornata. Western 
WiLLET. 
Summer resident; not uncommon. Rather common in 
migration on the plains, especially in the fall. In the spring it 
is most common from the first to the middle of May. Breeds 
throughout its range in favorable localities, but it is not a 
common breeder anywhere in Colorado and will not be found 
breeding at many places apparently well suited to its needs. 
Usually breeds from the plains to 7,000 feet, but occasionally 
much higher. 
261. Bartramia longicauda. Bartramian Sandpiper. 
Summer resident, common; in migration, abundant. A 
bird pre-eminently of the plains, where it breeds abundantly; 
only rarely met west of the mountains. Arrives the latter part 
of April and extends into the mountains only to 6,000 feet. 
263. Actitis macularia. Spotted Sandpiper. 
Summer resident; abundant. It is strange to think of a 
Sandpiper nesting on the top of a mountain, but so far up as 
this species can find a pond or small lake, it will build its nest, 
even to 12,000 feet. In the fall it ranges above the pines to 
14,000 feet. It also breeds on the plains and at all intermediate 
altitudes. As abundant in Colorado as anvwhere. Arrives 
about the first of May; leaves the higher altitudes in August, 
and most of them leave the State in September. A few remain 
until far into the winter, if not through the entire cold season. 
264. Numenius longirostris. Long-billed Curlew. 
Summer resident; common. Arrives about the last of 
April and breeds in suitable localities on the plains. Occurs 
on both sides of the range, but only in the lower portions, usu- 
ally not above 5,000 feet. A few have been seen as high as 
7,500 feet. 
265. Numenius hudsonicus. Hudsonian Curlew. 
Migratory; rare. All the records of this Curlew in Colo- 
rado come from the plains region east of the mountains, but as
