1883.] Grundtvig on Warblers of Wisconsin. ^ I 
Dendrceca palmarum ( Gm .) Bd. Perhaps this Warbler 
ought not to be included, as it was seldom seen in company with 
the rest, but generally noticed in the grass and in low bushes 
instead of in the trees. The first was seen May. 1, but it was not 
very common until the 8th ; the greatest number were noticed 
between this date and the 12th. 
Dendroeca pirnis ( Bartr .) Bd. May 31 I shot from out of 
a flock of D. coronata the first specimen of this Warbler, a fe- 
male. Afterwards I noticed them in many flocks but seldom 
found a flock composed entirely of this species, four or five being 
the most I have ever seen together. After May 6 it was very 
scarce, the last one appearing May 12, which was indeed a very 
peculiar specimen. It proved to be a female, with only the 
upper tail coverts olivaceus, the back and the head being entirely 
gray, there was no trace of a superciliary line, and below it was 
sordid whitish. Size, 4 yf, 24^, and 2. In fact, all of the spec- 
imens of this Warbler I examined were smaller than the measure- 
ments given in the u Key.”

A peculiar male specimen had three pairs of tail blotches. 
G-eothlypis trichas (A.) Cab. This Warbler was always 
noticed over wet, swampy places, it preferring the low bushes 
and shrubs to the higher trees. The first was seen May io, but 
they were not very numerous until the 18th, when both sexes 
appeared. They breed everywhere throughout the swamps. 
Myiodioctes pusillns ( Wils.) Bf. This Warbler was very 
rare in this section, only a few males being found. Two on the 
1 2th were the first observed; the 14th I noticed one, the 18th, 
two, the 22nd, one, and the 23rd, four, but not together ; the 
24th, 25th, and 28th one was noticed each day. Always found 
in bushes in low, wet places. 
Myiodioctes canadensis (A.) Aud. The first was seen 
May 10, two on the nth and two on the 18th. The first was 
seen May 10, two on the nth and two on the 18th. The 19th, 
however, it was very numerous, exceeded only by D. maculosa. 
The 20th it easily outnumbered the other species and remained 
quite numerous until the 22nd. The last two were observed 
May 31.
