1 Ca THE AMERICAN MIDLAND NATURALIST. 
Birds of Watertown, Wisconsin. 
BY BROTHER ALPHONSUS, C. S. C. 
My vacation in the summer of 1922 was spent at Water- 
town, Wisconsin, where I arrived on August 8th and re- 
mained until September 7th. This town of about nine thou- 
sand people is some forty miles southeast of Madison, the 
capital of the state. Watertown, which is situated in the 
fertile Rock River Valley, I found to be a favorable locality 
for bird study. In all I obtained ninety-one records, the 
largest number I have ever got at that particular season of 
the year. In fact, I doubt whether I have ever secured, even 
in Spring, more satisfactory results from my observations. 
Starting out every afternoon at 1:15 p. m. and remaining 
until 5 p. m., I found this-time of day equally as good for 
observation as the morning. In one respect I think the early 
afternoon was better than the morning, for then there was 
a clearer light in the tree-tops, which made it.easier to see 
the warblers. My list of warblers for this season of the year, 
I think, was remarkably large—twenty in all. 
I confined my observations chiefly to two places—a. wood 
with undergrowth and a small stream bordered by willows. 
Both localities proved very fruitful, but the grove gave me 
most of the warblers. Among the rare spceies were the fol- 
lowing: Lark Sparrow, Yellow-throated Vireo, Acadian Fly- 
catcher, Blue Gray Gnatcatcher, Prothonatory Warbler, 
Black-billed Cuckoo, Blue-winged Warbler, and Titlark. The 
Lark Sparrow I had not seen in Indiana for many years. The 
Yellow-throated Vireo is rare also in northern Indiana. The 
Acadian Fly-catcher, a species of this family that is seldom 
seen, was very common in the grove I visited in Wisconsin. 
The Blue Gray Gnatcatcher was observed on two days in 
different localities. The Prothonatory Warbler was observed 
once. The Black-billed Cuckoo was perhaps more abundant 
than the Yellow-billed. The Lincoln Sparrow, in small num- 
bers, was seen on two days. The Blue-winged Warbler was 
also found twice. The Rusty Black-bird, always very rare, 
was located near the stream on two days. The Golden-winged 
Warbler and a small flock of Titlarks were seen once.
