THE BIRDS OF WISCONSIN. 
a few nest in Wisconsin, even as far south as Jefferson County, 
although there is no actual record. Specimens have been 
taken near Jefferson, June 10. Young birds are often taken 
as early as the middle of August in the large tamarack 
swamps. Principally a frequenter of low lands, and willowy 
thickets, often in tamarack swamps. 
Wilsonia canadensis (Linn.). CANADIAN WARBLER. 
A common migrant during the latter part of May, and 
again in September. A few nest in central and northern Wis- 
consin, along the borders of hemlock swamps, but the great 
majority pass beyond our borders to summer. King mentions 
taking a fully fledged young bird near Worcester, July 19, 
1876 (1), and a pair were seen feeding young, which were 
flying about, on July 12, 1882, in Door County, to the north- 
ward of Sturgeon Bay (L. K.). Nelson reports it as a rare 
summer resident in northern Illinois. Grundtvig found it the 
most abundant warbler in Outagamie County in 1882 and 
1883, except Dendroica maculosa. All other observers report 
it as common, except King, who calls it rare in central Wis- 
consin, where it has been noted by others as abundant for the 
past forty years. More plenty along the borders of swamps 
abounding in a thick growth of coniferous trees than in the 
hardwood. 
Setophasa ruticilla (Linn. J. AMERICAN REDSTART. 
A summer resident. The redstart breeds abundantly in all 
deep, second-growth woods, though, as usual with many 
warblers, it prefers the vicinity of a lake, pond, or stream for its 
summer home. Nesting begins in May, : nd the family remain 
together the entire summer, a happy, beautiful, woodland- 
roving flock of parents and young. 
FAMILY riOTACILLID/€: WAGTAILS. 
Antlius pensilvanicus (Lath.). AMERICAN PIPIT. 
A common migrant, but not always to be depended upon in 
any locality. On the prairies, dry marshes, and along the lake 
shore it is sometimes abundant, especially in September and 
October, and even to November 1. Specimens were taken 
from a flock near Lake Koshkonong, June 3, 1879, but as 
might be expected, showed no indications of breeding soon.
