APPENDIX II. — 'AUGHEY ON LOCUST-FEEDING BIRDS. 



[19] 



I found a nest close to the lower edge of a bluff north of Cropsy's mill, two miles from 

 Lincoln Nehr. The yonng were already hatched out; taking as near a position as I 

 could, I watched the old birds feeding their young, on two days. The locusts were 

 yet comparatively small, and I could not tell even with my field-glass the character of 

 the food with any certainty, but concluded, as they flew to a spot which was covered 

 with locusts, for food, that they must be dining on them. Ou June 16 I shot one, and 

 found in its stomach 42 locusts and 33 small seeds. The variety was leucolcema of 

 Coues. » 



Family MOTACILLIDiE : Wagtails. 



Anthus ludovicianus, (Gm.) Licht. 



Titlarlc; Pipit; Wagtail. 



Only a few pass north through Eastern Nebraska during the last of April. They re- 

 turn in September. I examined the following in September, 1874. The migratory 

 locusts had reached and laid their eggs at this time :

Family SYLVICOLID^ : American Warblers. 



Mniotilta varia, (Linn.) Vieill. 



Blaclx-and-ivhite Creeping Wardler. 



Have only seen this bird in the wooded sections of Nebraska. Found a nest a few 

 miles south of Lincoln on the ground, at the edge of a strip of timber. Unfortunately, 

 I lost the exact date, but it was some time during the month of May, 1875. I watched 

 the old feeding the young, but could not determine exactly what kind of food they 

 brought them, but concluded it must be young locusts in part, as they flew from their 

 nests to some old breaking near by, which was covered with young locusts just hatch- 

 ing out. They flew to this old breaking anf! back to their nests with food every few 

 minutes. Ou June 5 I examined the stomach of one, that held 41 locusts, 12 other in- 

 sects, and a few seeds. 



Parula AMERICANA, (Linu.) Bp. 



Blue Yellotv-'bacTied • Warller. 



It reaches Nebraska about the 1st of May, and is found principally along timber belts 

 and in orchards. I have frequently seen the young soon after leaving the nest, but 

 the nest itself I have never found. Have never examined the contents of their stom- 

 achs, but have frequently seen them picking up locusts and other insects. Of locusta 

 they must consume large numbers, 



Protonotaria citrea, (Bodd.) Bd. 



Protlionotary Warhler. 



Have only seen this bird a few times in Southeastern Nebraska, in Richardson 

 County. There, in June, 1875, I observed it picking up locusts at the edge of a belt 

 of timber. 



Helmitherus vermivorus, (Gm.) Bp. 



Worm-eating Warmer. 



Like the last, have only seen this species in the southeastern part of the State, 

 There, in June, 1875, observed it feeding on locusts. Did not find its nests nor see 

 its young. 



Helminthophaga PiNt>s, (Linn.) Bd. 



Blue-winged Yelloiv Warmer. 



This species also only appears in the southeastern part of the State. Do not know 

 whether^it breeds within our borders. I have observed it but once feeding on locusts, 

 in June,"'1875, at the border of some timber, near the mouth of the Nemaha River.
