*Trndetenniiied. 



During the last season I also observed them feeding on locusts in Fremont, Nebraska. 



Regulus satrapa, Licht. 



Golden-cresied Kinglet. 



Abundant during some years in Northern Nebraska. Have not seen them south of 

 the Platte. In June, 1865, observed it picking up small locusts, east of Dakota City, 

 in a sparse wood near the river. 



Family CINCLID^E : Dippees ; Water Ouzels. 



ClXCLUS MEXICANUS, Sw. 



Western Bluebird. 



Rare in Nebraska. Seen it for the first time in August on the Niobrara, about seven 

 miles from its mouth, in a dense timber. I was near enough to it to observe it catch- 

 ing locusts. Hon. J. Sterling Morton says that they are abundant in Otoe County. 



POLIOPTILA CCERULEA, (Linn.) Scl. 



Blue-gray Gnat-catclier. 



Found sparingly in Eastern Nebraska. On June 2, 1865, I opened the stomach of 

 one near Dakota City. It contained a great number of the remains of small locusts. 

 I watched one feeding in a spot where locusts of all sizes were abundant on June 14, 

 1875. With my field-glass I observed that it picked out the small ones. I observed 

 the same phenomenon on June 2, south of Lincoln, Nebr. Judging from these few 

 observations, this species selects the small locusts when it feeds on them. 



Family PARID^ : TixsncE. 



LoPHOPHAXES BicoLOR, (Linn.) Bp. 



Tufted Titmouse. 



Abundant in Eastern Nebraska. Whenever the locusts were present, this bird seemed 

 to live almost exclusively on them. The following specimens examined :

L0PH0PH.4.NES ixoRXATUs, (Gamb.) Cass. 



Plain-crested Titmouse. 



Have seen none in Nebraska. In June, 1875, when at Cheyenne, Wyo., I was for- 

 tunate enough, some distance south of the town, to see a few. They were feeding on 

 loc usts and other insects, as I ascertained hj watching them with my field-glass. Coues 

 asserts that its habits are the same as the preceding, and if so it must destroy an im- 

 mense number of locusts throughout. the mountains.
