How drowsily he crew.”

And beautiful too is the allusion to the Owl by Longfellow, in Hyperion: “For the owl is a grave bird; a monk who chants midnight mass in the great temple of Nature.”

Kirtland’s Owl, which we present to our readers in the plate now before us, is one of the most recent additions to the Ornithological Fauna of this country, and was first brought to notice by Philo R. Hoy, M. D., an eminent naturalist and physician of Racine, Wisconsin, who has ascertained its occurrence, and has succeeded in obtaining several specimens in the neighborhood of that city.

It appears, however, to be by no means a common species, though having been observed in the season of incubation, as well as in the winter, it may be presumed to be a constant resident, and further investigation may bring to light full details of its history. It belongs to a group composed of several species of small owls, found in the northern regions of both continents, the most common of which, in this country, is the little Acadian Owl (Nyctale acadica), a curious and rather handsome little species not very well known in the rural districts, but sometimes occurring, and also occasionally captured, in the cities. It is the least of the owls of the Atlantic States. Another species is known as Tengmalm’s Owl (N. Tengmalmii), which inhabits the higher northern latitudes of America and Europe.

Like the other small species of its family, the present Owl probably subsists on the smaller birds and quadrupeds and on insects. The last form no inconsiderable portion of the food of the smaller Owls. We have repeatedly found the remains of insects in the stomachs of several species; and in 1851, during the period of the appearance of the Seventeen-year Locust (Cicada septemdecim) in the neighborhood of Philadelphia, we enjoyed an opportunity, in company with several members of the Academy of Natural Sciences of this city, of observing the common Red Owl (Ephialtes asio) while engaged in feeding on insects of that remarkable species. It captured them principally in an apple-tree in which it was first noticed, but occasionally pursued its object to the ground, and with a degree of adroitness and avidity which fully evinced that it had been accustomed to similar occupation.

Dr. Hoy’s description of the species now before us was first published in the Proceedings of the Philadelphia Academy, VI. p. 211, (Dec. 1852,) from which we make the following extract:

“But two specimens of this bird have been taken, to my knowledge; the first was captured in October 1851, and kept until winter, when it made its escape; the second, that from which the above description was taken, flew into an open shop, July 1852. It is strictly nocturnal, utters a low tremulous note, and is an active and efficient mouser.”

We have been informed by Dr. Hoy that during the past summer (1853,) he had succeeded in obtaining another specimen which proved to be a female. It is slightly larger than the male, but similar in all other respects.

The figures in our plate represent the male bird, and are about two-thirds of the size of life.
