This warbler is tolerably common during the migrations, 
but is less numerous as a breeding bird over the entire state. 
Given a wet woods with a fringe of brush and the Blue-wing 
is pretty certain to be present. One hearing of the curious 
song is enough to fix it in mind. While the nest is placed 
near the ground in the grass or rarely low bushes, the birds 
must usually be looked for in the tree-tops, or at least in the 
upper branches of the taller trees. If the bird be near the 
ground it is pretty certain proof of the presence of the nest. 
This warbler reaches northern Ohio during the last week 
in April, and remains until the middle of September. 
240. (642). HELMINTHOPHILA CHRYSOPTERA (Linn.). 33. 
Golden-winged Warbler. 
Synonyms: Helminthophaga chrysoptera, Sylvia chrysoptera, 
Vermivora chrysoptera, Motacilla chrysoptera. 
Blue Golden-winged Warbler, Golden-winged Swamp Warb- 
ler.

The distribution of this warbler in Ohio seems to be al- 
most identical with that of the Worm-eating Warbler, with 
the exception that it seems to be a little more northern. It 
has been found in Lorain county a half-dozen times, but 
is not kriown to have bred there. It is reported as breeding 
in Cuyahoga and Ashtabula counties, and is common lo- 
cally in the southern half of the state. It also nests on the 
ground, but is not so fond of the tree-tops for a perch. 
It is unwary, permitting a near approach. Its lazily uttered 
zee zee zee zee is unlike the song of any other bird, but 
might be mistaken for an insect.
