THE LITTLE SCREECH OWL.
Strix Asio, Linn.
PLATE XCVII. Adult and Young.
This Owl, although found in the Southern States, is there very rare. During a long residence in Louisiana, I have not met with more than two individuals. On advancing towards the confluence of the Ohio and Mississippi, we find them becoming rather more numerous; above the Falls of the former, they increase in number; and as the traveller advances towards the sources of that noble river, their mournful notes are heard in every quarter during mild and serene nights. In Virginia, Maryland, and all the Eastern Districts, the bird is plentiful, particularly during the autumnal and winter months, and is there well known under the name of the Screech Owl.
You are presented, kind reader, with three figures of this species, the better to shew you the differences which exist between the young and the full-grown bird. The contrast of colouring in these different stages I have thought it necessary to exhibit, as the Red Owl of Wilson and other naturalists is merely the young of the bird called by the same authors the Mottled Owl, and which, in fact, is the adult of the species under consideration. The error committed by the author of the "American Ornithology," for many years misled all subsequent students of nature; and the specific identity of the two birds which he had described as distinct under the above names, was first publicly maintained by my friend Charles Lucian Bonaparte, although the fact was long before known to many individuals with whom I am acquainted, as well as to myself.
The flight of the Mottled Owl is smooth, rapid, protracted and noiseless. It rises at times above the top branches of the highest of our forest trees, whilst in pursuit of large beetles, and at other times sails low and swiftly over the fields, or through the woods, in search of small birds, field-mice, moles or wood-rats, from which it chiefly derives its subsistence. On alighting, which it does plumply, the Mottled Owl immediately bends its body, turns its head to look behind it, performs a curious nod, utters its notes, then shakes and plumes itself, and resumes its flight
