Helminthophaga chrysoptera, (Linn.) Cab. 

 Blue Golden-winged Warbler. 

 Occasionally seen in Eastern Nebraska, but have not met with it during our locust 

 years. Judging from the known characters of its congeners, it must also prey oa 

 these inseets. 



Helminthophaga rueicapilla, (Wils.) Bd. 

 Nashville Warbler. 

 This bird arrives in Eastern Nebraska about May 1, and some seasons at least breeds 

 in and on the borders of the timber belts. On June 10, 1865, 1 found a young one that 

 had just left the nest and flew with difficulty. As it was alone, I killed it to find the 

 contents of its stomach. It contained '21 locusts and a few other insects. The nests 

 I have never found. I, during the same month, frequently saw old birds feed on lo- 

 custs. The birds, owing to their small size, were hard to watch, except at the edge of 

 the timber^ where it was sparse. 



Helminthophaga Virginia, Bd. 

 Virginians Warbler. 

 Have only seen one specimen of this bird in Southwestern Nebraska in a narrow belt 

 of timber in the Republican River Bottom, in Hitchcock County. Know nothing 

 from observation of its habits, but suppose, from the known character of its congen- 

 ers, that it also feeds on locusts. 



Helminthophaga peregrina, (Wils.) Cab. 

 Tennessee Warbler. 

 Occurs sparingly in Eastern Nebraska in the latter part of May, as it is moving north. 

 In June, 1865, 1 observed them flitting among the tree-tops in a timber south of Dakota 

 City. One evening, at the edge of the timber, half a dozen of them toward evening 

 lighted on the ground about two rods from me, where the soil was covered with young 

 locusts. With my field-glass I could distinctly see the birds pick up the locusts. I 

 never found any indications of their breeding in this State. 



Dendrceca iESTiVA, (Gm.) Bd. 

 Blue-eyed Yellow Warbler ; Golden Warbler ; Summer Warbler. 

 Abundant in Nebraska. 



This bird has exhibited characters in relation to the locusts different from any that 

 I have thus far referred to, as the following examples show :
