This species can readily be distinguished from the next, which is the only one of the same size, by its long ear tufts; it is also darker, and the markings on the breast are largely in the form of bars. In the northern portions of the United States, this species is probably the most abundant of owls, excepting the little [Screech Owl]. It is often quite common, where its presence is little suspected, because, unless disturbed, it flies only at night and is a rather silent species. During the daytime it is usually sitting upright in the dense tops of evergreen trees. Crows often discover them, and proclaim their hiding place to the whole neighborhood by their incessant cawing. Owls of all kinds are in disfavor with crows.
Notes.—A soft-toned “wo-hunk, wo-hunk.” (Bendire.)
Nest.—They lay from four to seven pure white eggs, usually in old crow nests.
Range.—Resident from the Gulf to Nova Scotia and Manitoba.
SHORT-EARED OWL
367. Asio flammeus. 15.5 in.
Ear tufts very short; general color buffy, not nearly as brown nor as dark as the last species usually is. They are not nearly as nocturnal as most of the owls, and most of their hunting is done about dusk, when they may be seen flying close to the ground over marshes or low land. Their flight is perfectly silent, which aids them in securing their prey of field mice, which they usually get without stopping in their flight, just swooping down, extending their long legs, armed with wicked little claws, and it is all over with the little rodent, he being carried to a nearby stump, and devoured, fur, bones and all.
Notes.—A very short, shrill cry, evidently their call note, and a low clucking uttered as they swoop over your head; besides the usual snapping of the bill.
Nest.—On the ground, usually in marshes; the four to seven eggs are pure white, (1.55 × 1.25).
