of this species in the state. It is doubtful if it occurs, even in 
limited numbers, much north of this locality, as several com- 
petent observers and sharp collectors have failed to find it. 
FAMILY MNIOTILTID/E: WOOD WARBLERS. 
Mniotilta varia (Linn.). BLACK AND WHITE WARBLER. 
An abundant migrant, and tolerably common summer 
resident. This species is one of the first of the warblers to 
arrive, appearing in the southern part of the state with the 
myrtle and palm warblers during the latter part of April. It 
is common from then until close to the breeding season, when 
its numbers are greatly diminished. On the southern migra- 
tion it begins to increase in numbers in August and is again 
abundant until October. 
Protonotaria citrea (Bodd.). PROTHONOTARY WARBLER. 
In suitable localities in the southern and western parts of 
the state the prothonotary warbler is not a rare summer 
resident. It was first noted at Lake Koshkonong in 1867, 
since which time it seems to have become more plenty. Speci- 
mens have been recorded from nearly all parts of southern 
and central Wisconsin. Mr. Clark has so far failed to find it 
in Dunn County. The northernmost record we are able to 
obtain is for Shiocton, Outagamie County, May 4, 1882 (1). 
Apparently more common along the Mississippi than else- 
where in the state. Most observers fail to visit the dense, 
miry, weed and willow covered overflown swamp lands where 
this bird makes its summer home. Considerable numbers 
nest yearly at Lake Koshkonong. In migrations it visits the 
woods with warbler flocks. 
Helmitlierus vermivorus (Omel.J. WORM-EATING WARBLER. 
One of the southern species that rarely straggle to Wis- 
consin. Thure Kumlien procured one specimen at Lake 
Koshkonong in May, 1873, and one in May, 1877. We have 
seen a specimen mounted at a taxidermist's shop in Mil- 
waukee which was said to have been taken at that city, and 
there was no reason to doubt the statement. Dr. Hoy says : 
"A few nest in this section. Rare." (Racine.) As we remem- 
ber it he procured but three specimens in all, and knowing it
