THE BIRDS OF WISCONSIN.

eastern Wisconsin during the migrations. Mr. VVm. Brewster 
has kindly examined our specimens and finds perfectly typical 
examples of both races. 
Serums noveboraeensis notabilis (Ridgw.J. GRINNELL'S WATER- 
THRUSH. 
Regular migrant, even in the extreme southeastern part of 
the state. Specimens of this race were identified by Mr. Wm. 
Brewster among the water-thrushes sent for his inspection. It 
occurs at the same time, and in company with the preceding, 
and may possibly be the nesting form in the western part of 
the state. Unfortunately, we have no breeding birds from this 
district. 
Seiurus motacilla (Vieill.J. LOUISIANA WATER-THRUSH. 
The Louisiana water-thrush occasionally occurs in the 
spring in southern Wisconsin, and doubtless breeds, as this is 
the extreme northern part of its range. One specimen has 
been taken at Delavan, Walworth County (May 18, 1900. 
N. H.), and one in Milwaukee County (April 25, 1897 — Cope- 
land and Russel), besides four or five in all about Lake 
Koshkonong, during the past fifty years. 
Oporornis formosa (Wils.J. KENTUCKY WARBLER. 
We appear to be a little too far north for this exquisite 
species. In southern Wisconsin it is very rarely taken during 
the spring migrations, when an occasional individual seems to 
wander out of its usual range. Dr. Hoy took one specimen at 
Racine (May 10, 1851), and we have but six other records for 
the state for sixty years, all about Lake Koshkonong, in 
spring. 
Oporornis agilis (Wils.). CONNECTICUT WARBLER. 
Not so rare a species as generally supposed. By one 
familiar with its haunts, song and habits, it can be found in 
some numbers during the latter part of May, the first week of 
June, and again during September. It is generally spoken of 
as more common in spring than fall, but we are unable to see 
any material difference, and if anything find more in autumn, 
as the young are less shy than the spring adults, and are con- 
sequently more often seen. Dr. Hoy considered it not 
uncommon at Racine, and shot a mated pair, about to begin 
nest building. In Jefferson County a pair was found, June 16, 
1874 (L. K.), putting the finishing touches upon their nest. It
