The wild pigeon is now too rare to be included among our bird
neighbors; but its beautiful relative, without the fatally gregarious
habit, still nests and sings _a-coo-oo-oo_ to its devoted mate in
unfrequented corners of the farm or the borders of woodland.
Delicately shaded fawn-colored and bluish plumage. Small heads,
protruding breasts. Often seen on ground. Flight strong and rapid,
owing to long wings.
Mourning or Carolina Dove.
