_Protonotaria_, BAIRD, Birds N. Am. 1858, 239. (Type, _Motacilla
citrea_, BODD.)
[Line drawing: _Protonotaria citrea_, Baird.]
GEN. CHAR. Characterized by its long, distinctly notched bill, and
long wings, which are an inch longer than the slightly graduated tail
(the lateral feathers about .12 of an inch shorter). The under
tail-coverts are very long, reaching within half an inch of the tip of
the tail. The tarsi and hind toe are proportionally longer than in the
true Warblers. The notch and great size of the bill distinguish it
from the Swamp Warblers. Nest in holes; eggs much blotched with
reddish.
The only North American species belonging to the group appears to be
the old _Sylvia protonotaria_ of Gmelin.
