to have any provincial name.

WILSON, PLATE XLY. FIG. IL — YOUNG BIRD. 
The male of this species has just been described ; 
the present is the young bird as he appears for the first 
two seasons : the female differs very little from it, and 
chiefly in the green olive being more inclined to ash. 
This is one of our summer birds, and, from the cir- 
cumstance of being found off Hispaniola in November, 
is supposed to winter in the islands. They leave Penn- 
sylvania about the 20th of September; are dexterous 
flycatchers, though ranked by European naturalists 
among the warblers, having the bill notched and beset 
with long bristles. 
In its present dress the redstart makes its appearance 
in Pennsylvania about the middle or 20th of April ; 
and, from being heard chanting its few sprightly notes, 
has been supposed by some of our own naturalists to 
be a different species. I have, however, found both 
parents of the same nest in the same dress nearly ; the 
female, eggs and nest, as well as the notes of the male, 
agreeing exactly with those of the redstart ; evidence 
sufficiently satisfactory to me. 
Head above, dull slate ; throat, pale buff ; sides of 
the breast and four exterior tail feathers, fine yellow, 
tipt with dark brown ; wings and back, greenish olive ; 
tail-coverts, blackish, tipt with ash ; belly, dull white ; 
no white or yellow on the wings ; legs, dirty purplish 
brown ; bill, black. 
The redstart extends very generally over the United 
States ; having myself seen it on the borders of Canada, 
and“also in the Mississippi territory. 
This species has the constant habit of flirting its 
expanded tail from side to side, as it runs along the 
branches, with its head levelled almost in a line with 
its body ; occasionally shooting off after winged insects,
