THE BIRDS OF WISCONSIN. 
way possible here in its summer home. In some parts of the 
state it is still fairly common. 
Tliryotliorns Inrtovicianus (Lath.). CAROLINA WREN. 
A rare straggler to Wisconsin. We have never met the 
species in the state, and its presence must be considered as 
merely accidental. One specimen was preserved by Thure 
Kumlien, which was taken in the summer of 1878 near Janes- 
ville. It is recorded by Dr. Hoy, a single bird, from Racine, 
July 5, 1852. One other specimen at least was taken by Hoy 
of which we have personal recollection, but the record cannot 
be found. A single specimen secured at Milwaukee in the 
summer of 1881, was seen at the shop of a taxidermist in that 
city. 
Troglodytes aedon Vievll. HOUSE WREN, 
A common migrant in eastern Wisconsin in almost equal 
numbers with the next. It breeds sparingly anywhere from 
the southern border northward. It arrives the last week of 
April and is common until the middle of May, when all but a 
few pass northward. It nests late in June, in towns and 
villages as well as in the more retired woods. Mr. Brewster 
has examined our series of house wrens, and pronounces nearly 
half to be typical a'edon. 
Troglodytes aMon azteeus Buird. WESTERN HOUSE WREN. 
In a series of house wrens from southern and eastern 
Wisconsin, Mr. Wm. Brewster finds typical examples of both 
forms, aedon and azteeus, the latter slightly predominating in 
numbers. These specimens were nearly all taken during the 
spring migrations of various years, and give no clew to the dis- 
tribution of the two forms during the breeding season. The 
azteeus averaged a little later, but both were sometimes taken 
on the same day. As the house wrens do not nest until June, 
as a rule, and this series was mostly made in late April and 
May, no actual breeding birds at present being available, we 
are unable to state whether this form nests within the state or 
not. Mr. Clark finds it a common migrant in Dunn County, 
and notes that it may occasionally nest, as he has seen it in 
mid-summer. Possibly these birds, nesting in that portion of 
the state, are azteeus, but actual breeding birds must be had 
before the summer range of the two forms in the state can 
be definitelv known.
