the Missouri river, in Nebraska and Iowa, but no distinction 

 is made for the present purpose. May 10 and 17 represent 

 all-day field trips ; on the other days observations were en- 

 tirely on the College campus and its immediate vicinity. 



With the exception of a few of the species which breed in 

 this locality, such as the Yellow warbler, the Redstart, the 

 Maryland Yellow-throat, and the Yellow-breasted Chat, the 

 Tennessee Warbler was the only one which I heard in song. 



Below are a few notes on each species which are intended 

 to show briefly the general status of these warblers in this 

 vicinity in order that this year's records may have a proper 

 setting. 



1. Myrtle Warbler (Dendroica coronata). — ^This is a regular and 

 very common migrant every year. Ttiis season, iiowever, it was 

 not observed with quite the usual frequency. 



2. Yellow Warbler {Dendroica ce. cestiva). — A most abuudaut 

 summer resident. 



3. Black-poll Warbler {Dendroica striata). — A regular and com- 

 mon migrant in the spring, and more or less c-ommon also in the 

 fall. 



4. Black and White Warbler {Mniotilta varia). — This unobtru- 

 sive little warbler seems to be quite irregular from year to year. 

 In 1912 it did not come under my observation at all. To see two 

 or thi*ee in a single day, and without making any special search, 

 makes this species seem almost abundant. 



5. Black-throated Green Warbler {Dendroica virens). — Was noted 

 several times. It has been observed occasionally in other years 

 and is probably a regular migrant, although by no means common. 



6. Wilson Warbler {Wilsonia p. pusilla) .—Wo\x\A be considered 

 tolerably common this season. It was observed on a number of 

 occasions, and in widely separated areas. Up to this year I have 

 regarded this species as rather rare. While specimens were not 

 taken, I hardly think there is any possibility of our having con- 

 fused this bird with the Pileolated Warbler {TV. p. pileolata), 

 whose range is said to reach Nebraska. These warblers impress 

 one with their activity, and their liabit of picking insects from 

 leaf or flower while pausing on the wing. Several years ago I saw 

 one chased into a thicket by a small hawk, probably a sharp- 

 shinned. 



7. Redstart {Setophaga ruticilla). — A regular and tolerably 

 common migrant, and occasionally breeding here. This year their
