“I shot this bird in the vicinity of Green Bay, when on my way across
to the Mississippi; but the drawing which I made of it on the spot has
been lost. It was about the size of _Strix acadica_, of a dark grey
color, with the tail long and deeply forked; but I am unable to
describe it more particularly, the Journal in which it was noticed
having been, along with others, destroyed by the great fire which
happened in New York some years ago.” (Audubon, as above.)
The bird here alluded to has never again been observed so far as we have
learned. The description probably applies to an unknown species, and
certainly to one not known as an inhabitant of the United States.
