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.
