WYOMING Birpbs. 27 
258a. Catoptrophorus semipalmatus inornatus: Western Willet. 
This species is probably decreasing in this state. Knight 
said it was a rather common summer resident about semi- 
alpine lakes and ponds. Richard, Blackwelder, Warren and 
Walker report it. Most of the records are for the lower 
altitudes and during migrations. 
261. Bartramia longicaude: Upland Plover. 
This bird, better known as Bartramian Sandpiper, has been 
' reported recently by only Metz and Clearwaters. 
263. Actitis macularius: Spotted Sandpiper. 
Abundant summer resident from the lower altitudes to the | 
alpine lakes. 
264. Numenius americanus: Long-billed Curlew. 
Fairly common summer resident over most of Wyoming. 
CHARADRIIDAE (Plovers). 
The Plovers are typically shore birds like the Snipes, but they 
have shorter bills, not adapted to probing, so that they collect their 
food mostly from the surface. They are also quite likely to breed 
in the meadows away from the water. They feed almost entirely 
upon insects, including locusts, crickets, caterpillars, moths, wire 
worms, cut worms, plant beetles, mosquitoes, and mosquito larvae. 
They are of considerable economic value and are not harmful in 
the slightest degree.
