The Barn Owl (Strix pratincola), as well as the Marsh Owl (Otus brachyotus), we have known to occur in open fields, where but little concealment was possible.
The Red or Mottled Owl is very persistent in its locality, and the same pair probably returns to the woods that it has previously occupied in preceding seasons, in some measure disregarding encroachments on its extent. In a small tract of timbered land at Powelton, the hospitable residence of John Hare Powel, Esq., surrounded by villages constituting a portion of the suburbs of Philadelphia, a pair of this species continued to appear and to raise broods of young until within a period of only two or three years past, notwithstanding constantly occurring chances of molestation.
An interesting fact relating to the species just mentioned (Scops asio), has recently been communicated to us by our esteemed friend, Mr. William Kite, of Chester county, Pennsylvania, a careful observer, much attached to the pursuit of natural history. He made the singular discovery that in this species the early ceremonies in the association of a pair about to assume the duties of incubation were for the greater part performed on the ground, and were accompanied invariably by unusual and continued cries, thus illustrating in a striking manner the strong analogy of these birds to the cat-like quadrupeds. This remarkable circumstance we regard as new in the history of this family of birds, and the observation of other species would be in a high degree interesting.
Further investigations and collections in this family are particularly desirable in the western and northwestern regions of North America, and will very probably result in the discovery of species not now known to naturalists.
B.
Doubtful and obscure species which have been described as inhabiting America north of Mexico:—
1. Strix wapacuthu. Gm., Syst. Nat. I., p. 291. (1788.) Pennant, Arctic Zoology I., p. 268. Rich. and Sw. Fauna Boreali Americana, Birds, p. 86, 99.
“The Spotted Owl (Wapacuthu) weighs five pounds, and is two feet long and four broad; the irides bright yellow; bill and talons shining black, and much curved, the former covered with bristly hairs projecting from the base; space between the eyes, the cheeks, and throat, white; on the top of the head, and on each side of the concha, the extreme parts of the feathers are dusky black; concha dirty white; scapularies, with the lesser and greater coverts of the wings, white, elegantly barred with reddish dusky spots pointing downwards; the quill feathers and tail are irregularly barred and spotted with pale red and black; back and coverts of the tail white, with a few dusky spots; under coverts and vent feathers white; the breast and belly dusky white, crossed with an infinite number of narrow reddish bars; the legs are feathered to the toes; the latter covered with hairs like those of the bill, but not so strong.
“This bird is an inhabitant of the woods, makes a nest in the moss on dry ground, lays from five to ten white eggs in May, and the young fly in June, and are entirely white for some time after. They feed on mice and small birds, which they generally kill themselves. Hutchins’ MSS., p. 99.” Fauna. Bor. Am., Birds, p. 99.
This species, if distinct from the Snowy Owl, is absolutely unknown to naturalists, never having been noticed by any traveller since Mr. Hutchins. Though, from the description above quoted, apparently a peculiar species, the same name is given by the natives in the vicinity of Hudson’s Bay, to the Snowy Owl, according to Mr. Hearne (Journey to the Northern Ocean, p. 402. London, 1795, quarto); and it, too, makes its nest on the ground. With so little positive information, it is impossible to form more than conjectures respecting the bird alluded to in the description, and it must be left as an interesting matter of inquiry for future explorers and naturalists.
It may be observed with reference to Mr. Hearne’s statement, that if the bird he alluded to was really an Owl, it differs from any other American species in laying from “five to ten eggs.” Careful and evidently accurate statements respecting the incubation of nearly all the northern species, are given by Dr. Hall, in his “Sketch of the Zoology of the District of Montreal” (manuscript in our possession); and no species is represented as producing more than “four to five eggs,” except the Mottled Owl (Scops nævia), which lays “five to six.” The Snowy Owl, it is stated by Dr. Hall, lays “two white eggs.”
