BIRDS OF MINNESOTA. 375 
deal less time than it takes to write one of these lines, the 
beautiful, delightful warble lay at my feet. I hear that it has 
been seen late in August by those who sought to know the bird 
thoroughly. Mr. Grantdid not meet with it at Vermilion lake, 
but Mr. Lewis did, under circumstances which justify the pre- 
sumption that it breeds there in company with so many of the 
warblers. 
SPECIFIC CHARACTERS. 
Above olive green, rather brighter on the rump; beneath 
entirely greenish yellow, except a little whitish about the vent; 
the sides tinged with olivaceous; a concealed patch of brown- 
ish-orange on the crown, hidden by the olivaceous tips to the 
feathers; eyelids and an obscure superciliary line, yellowish, 
and a dusky, obscure streak, through the eye.. 
Length, 4.70; wing, 2.25; tail, 2. 
Habitat, eastern North America. 
HELMINTHOPHILA PEREGRINA (WiLson). (647.) 
TENNESSEE WARBLER. 
Abundant in the season of its migration, the Tennessee 
Warbler is a fairly represented summer resident, arriving 
from the 5th to the 10th of May, and remaining until about the 
second week in September. They build their nests in, or in 
the vicinity of forests, on the ground, well concealed by brush 
and dead leaves. It is composed entirely of fibrous strips of 
bark outwardly, and of fine grasses interiorly. Five eggs, 
more or less speckled with brown, especially about the larger 
end, were found in a nest at Lake Minnetonka, June 5th, 1881. 
They are a very nervous, active and energetic species, exceed- 
ingly difficult to follow with the best eyes or a field-glass, flit- 
ting constantly to and fro through the boughs in searching for 
their food, keeping up a short chirp. 
This has been accounted a somewhat northerly species, and 
not without reason on account of the disproportionate number 
seen during their migration, but I am satisfied it should not be 
specialized as such. In the fall, and after the earlier frosts, it 
is not a very uncommon thing tou meet scattering parties of 
them mingled with other species, making their way towards 
the south. Itis not abundant for its species, except during 
migration when few other of the warblers are ‘more so. At 
St. Vincent, Mr. Washburn recorded it in the latter part of 
July, 1885, as very frequently seen ‘‘in scrub willows and trees 
bordering the Red river.” I get similar records from different
