ECONOMIC RELATIONS OF OUR BIRDS.

food in a manner similar to that of the last species, but is perhaps a more expert 
liy-catcher. 
54. IcTERiA VIRENS (LiNN.), Bd. YELLOW-BREASTED CHAT. Group I. 
Class b. 
This is another of the birds which is seen but rarely in Wisconsin, and its regu¬ 
lar occurrence north of Pennsylvania is disputed, it is described as somewhat 
ten*estrial in its life, frequenting tangled thickets of vines, briers and brambles, 
and keeping itself very carefully concealed. 
Food: Large black beetles and other insects (Wilson). Beetles, and berries of 
various kinds (De Kay). Spiders, and insects found among the thick shrubbery 
of brier patches and on the ground among the leaves (Samuels). Chiefly beetles 
and other insects, berries and other small fruits. It is said to be especially fond 
of wild sti’awberries (Brewer). 
55. Myiodioctes mitratus (Gm.), Aud. HOODED FLY-CATCHING 
WARBLER. Group II. Class a. 
As with the last, this is a southern species, probably to be found only along 
the lake shore, and there but rarely. 
Food: Insects taken on the wing (Bi'ewer). Winged insects (Wilson). In¬ 
sects which it takes on the wing (De Kay). 
56. Myiodioctes pusillus (Wils.), Bp. BLACK-CAPPED FLY-CATCHING 
WARBLER. Group II. Class a. 
his species is credited to North America at large, and regarded as common; 
yet it has not been my good fortune to meet with it. Nelson states that it is 
found along the borders of woods and about willow patches, and that it is a 
common migrant in Northeastern Illinois, May 7th to 25th, and the first of Sep¬ 
tember. Since writing the above, one of these birds was picked up dead at 
River Falls after the cold wave of May, 1882, by which it had been killed. 
57. Myiodioctes Canadensis (Linn.), Aud. CANADA FLY-CATCHER. 
Group I. Class a. 
This bird is chiefly a migrant in the United States. It is probable, however, 
that it breeds regularly in the northern portion of the state, as it does in Maine, 
for I obtained a young specimen, fully fledged, near Worcester, July 19,1876. 
It was on the border of a cedar swamp flitting along among the lower branches 
of the hemlocks and pines which abound in that region. In the southern por¬ 
tion of the state, during the migrations, it frequents the densely wooded banks 
of streams. It is not common, at least in Central Wisconsin. 
Food: Of three specimens examined, two had eaten flies; one, a hymenopter- 
ous insect; one, beetles; and one, larvae. 
Insects (Wilson). Insects taken on the wing (Samuels). 
58. Setophaga ruticilla (Linn.), Sw. AMERICAN REDSTART. Group I. 
Class b. 
A few Redstarts breed in the southern part of the state, but the great major¬ 
ity pass northward, at least beyond Waupaca, to nest. During the last days of 
July or early in August, they become suddenly abundant and remain so until 
the middle of September, after which only loiterers are to be found. Its favorite 
haunts are the interior woodlands, both damp and dry, the wooded banks of
