APPENDIX II. AUGHEY ON LOCUST-FEEDING BIRDS. [21] 



Dendrceca ccerulescens, (Linn.) Bd. 

 JBlack-throated Green WarhUr. 



Is present in spring and fall during its migrations in Eastern Nebraska, but sparingly. 

 Shot one in September, 1874, near Lincoln, Nebr., which had 2.1 locusts in its craw and 

 15 other insects. Found no traces of its breeding in the State. 



Dendrceca ccerulea, (Wils.) Bd. 



Ccerulean Warhler. 



Abundant in Eastern Nebraska along the wooded river-bottoms, where it is in the 

 habit of breeding. All the nests (six) that I have found in thirteen years in Nebraska, 

 were built in phun-bushes, from two to four feet from the ground. One such I watched 

 near Pilgrim Hill, in Dakota County, Nebraska, in June, 1865. The parents every few 

 minutes brought a locust to their young. I saw thorn picking them up, with my field- 

 glass, and carrying them to their nests. An old field, a hundred yards distant from 

 their nest in a plum-grove, gave tJiem excellent feeding-grounds. 



Dendrceca coronata, (Linn.) Gray. 



Yellow-rum]) Warbler. 



Have seen young birds in Eastern Nebraska on several occasions, but have failed to 

 find the nests. It is frequently seen along our timber belts. Examined the craw of 

 one in June, 1875, that contained 31 locusts and 5 other insects. In June of the pres- 

 ent year, observed one picking up locusts on the Antelope Bottom. Observed the oper- 

 ation carefully with my field-glass. 



Dendrceca blackburni^, (Gm.) Bd. 



Blaclcburnian Warbler. 



Occasional! y seen in the borders of woodlands in Eastern Nebraska. Have as yet 

 found no traces of its breeding here, and made no observations on its feeding habits. 

 I conclude, however, from the character of its congeners, that it must also feed on the 

 locusts. 



Dendrceca striata, (Forst.) Bd. 



BldcTc-jpoll Wa7'ble7\ 



Rather common in Eastern Nebraska during its migrations toward the north. Found 

 no traces of its breeding here. The following were examined for locusts :

Dendrceca castanea, (Wils.) Bd. 



Bay-breasted Warbler 



Occasionally met with in Eastern Nebraska, but found no indications of its breeding 

 here. Shot one specimen in September, 1874. Found 19 locusts and 22 other insects in 

 its stomach. 



Dendrceca pennsylvanica, (Linn.) Bd. 



Chestnut-sided Warbler. 



Rather common in Eastern Nebraska during its migrations. No indications of its 

 breeding here. Shot one in September, 1874, and found 17 locusts and 21 other insects 

 in its stomach. 



Dendrceca maculosa, (Gm.) Bd. 



Black-and-yellow Warbler. 



Occasionally seen on its migrations in Northeastern Nebraska. In May, 1865, ex- 

 amined the craw of one near Ponca, Dixon County, Nebr. It contained 23 locusts and 

 17 other 4nsects.
