Notes on the Different Birds.

miles from the Wisconsin boundary). I have not yet had the 
opportunity to trace it further north. 
Helmitherus vermivorus (G-mel.) belongs to the Carolinian 
fauna, but is met with breeding at Racine (Hoy). Helmin- 
thophila pinus (Linn.) is likewise a southern bird; but Cooke 
thinks that he has seen it in Jefferson Co. Might it not very 
likely have been Protonotaria citrea f

119-126. E. 183-201. W. 63-66. T. 43-4T. B. (measured on 
the side) 11-14. In 1882 two males were seen May 15. A single 
one the 18th. The next two days singly in several flocks of 
warblers. On the 21st both sexes extremely numerous. Only 
exceeded in number by Dendroica striata , Helminthophila pere- 
grina and Dendroica maculosa. Migration ended the 27th. In 
1883, a single male May 18 and 20. Two the 21st. The day after, 
several of both sexes. Not nearly so many as the previous year 
but there were probably more that bred. At any rate this species 
was noticed oftener in breeding time in 1883 than in the pre¬ 
vious year. Not a few breed in open damp woods and thickets, 
especially hazel. But I could not find a nest. Strangely enough 
this bird was not seen by Cooke in Jefferson Co. It appears 
also not to have been met with by King. At Racine two nests 
were found (Hoy).

109-117. 175-185. W. 59-63. T. 41-43. On May 24, 1883, 
I shot a female without crown-patch. In 1882 this species was 
seen the 4th of May singly in several warbler-flocks. Five in 
company in some bushes near Wolf River. May very likely have 
been in the swamp before. May 5, several. 6th, the most nu¬ 
merous warblers in the bushes west of Wolf River. From 7th 
to 9th only a few. 10th, tolerably plenty everywhere. Increased 
in number till May 12, when it was only exceeded by Setophaga 
ruticilla. After this it was scarce near the river. Migration 
ended the 23d. In 1883 several were seen in a large warbler- 
flock May 7. Two, May 10. First female, 18th. Many males in 
a flock the 30th. A few the following day. 24th, a number of both 
sexes, but very few in comparison with the previous year. In 
1882 several pairs must have bred in East Swamp where they
