Tail long; eyes small and yellow. This large owl is only found in Northern United States during the winter. Its tail is unusually long, as are all its feathers, thereby making it appear a very much larger bird than it really is; it weighs but little more than the [Barred Owl]. They do not appear to be in especial abundance anywhere, but occasionally large flights of them will occur in some parts of the country; they seem to occur most freely in Minnesota and North Dakota. They are nocturnal like the majority of the family, and subsist largely upon mice and hares.
Nest.—Of sticks, in trees, usually pines, in heavily wooded districts; eggs white (2.15 × 1.70).
Range.—Breeds from southern Labrador, Hudson Bay and Alaska northward; winters south to the northern border of the United States and casually to Long Island and Illinois.
RICHARDSON OWL
371. Cryptoglaux funerea richardsoni. 10 in.
This species bears considerable resemblance to the little [Acadian Owls], but is grayer; the top of the head has numerous round white spots and the wing coverts are spotted with white.
Nest.—Usually in holes of trees; eggs white.
Range.—Breeds throughout Canada, and possibly in the northern parts of the northern states; winters south to northern United States.
