Wing, 6.90–7.30; tail, 3.50–4.50; culmen, .60–.65; tarsus, 1.35–1.45; middle toe, .80–.90. (Three specimens.) Hab. North Pacific coast of North America from Sitka to Washington Territory, and Western Idaho.
The zoölogical characters of the different varieties of the Scops asio having been thus indicated, we proceed to consider the species as a whole, and to point out the more important features of its habits and history.
Habits. The common Mottled Owl has an extended distribution throughout the temperate portion of North America. It is also the most numerous of this family wherever found. It does not appear to have been detected in any part of the Arctic regions. Although given on the authority of Fabricius as a bird of Greenland, it is not retained in the list of Reinhardt. It was not met with by Richardson, nor is any reference made to it in any of the Arctic notes furnished by Mr. MacFarlane or others. It is quite common throughout New England, as well as in the Central, the Western, and some of the Southern States. Mr. Boardman gives it as resident, but not very common, near Calais, where it breeds. It is found near Hamilton, Canada, according to McIlwraith, but it is not common, although Dr. Hall found it quite numerous in the vicinity of Montreal. Mr. Downes does not mention its occurrence in Nova Scotia. It was found breeding by Dr. Lincecum, at Long Point, Texas. It occurs in California, and as Scops kennicotti as far to the northwest as Sitka.
The Mottled Owl is nocturnal in its habits, never appearing abroad in the daylight except when driven out by the attacks of hostile birds that have discovered it in its retreat. Its eyes cannot endure the light, and it experiences great inconvenience from such an exposure. During the day it hides in hollow trees, in dark recesses in the forests, or in dark corners of barns, and comes out from its retreat just before dark. During the night it utters a very peculiar wailing cry, not unlike the half-whining, half-barking complaints of a young puppy, alternating from high to low, intermingled with deep guttural trills. These cries, which are sometimes prolonged until after midnight, usually elicit an answer from its mate or companions, and would seem to be uttered as a call soliciting a reply from some lost associate. When kept in confinement the Mottled Owl soon becomes familiarized to its new mode of life, and rarely attempts to injure its captors, though it will at first snap its bill in a threatening manner and manifest considerable irritation on being approached or handled. In the daytime they keep secluded, appear sleepy or stupid, with half-closed eyes, but, as night approaches, become quite lively and eager for their food. They utter their nocturnal cries in confinement, the doleful sounds of which are in singular contrast with the lively and excited air of the birds as they utter them. Their flight is noiseless and gliding, and they move in a manner so nearly silent as to be hardly perceptible. They are excellent mousers, and swallow their food whole, ejecting the indigestible parts, such as hair, bones, feathers, etc.
Wilson caught an adult bird, and kept it in confinement some time. At first it was restless and attempted to escape, beating against the glass of the window repeatedly, and several times with so much violence as to stun itself. In a few days it was reconciled to its situation, and became quite tame and familiar, and in the evening was very lively, sprightly, and active.
The food of the Screech-Owl is chiefly small quadrupeds, insects, and occasionally, when they have young, small birds. They destroy a vast number of mice, beetles, and vermin, and are of great service to the agriculturist, although their services are not appreciated, and they are everywhere persecuted and hunted down without mercy or justice.
The nest of this species is usually constructed in hollow trees or stumps, most frequently in orchards in the vicinity of farm-houses, and not more than six or seven feet from the ground. Mr. Audubon states, however, that he has sometimes found them at the height of thirty or forty. To show the provident habits of this Owl in procuring for its young a great superabundance of food, Mr. Nuttall mentions finding in the hollow stump of an apple-tree, which contained a single brood of these young Owls, several Bluebirds, Blackbirds, and Song-Sparrows.
Dr. Cooper, on the other hand, relates an instance where one of these Owls resided as an inmate in a dove-cot, where it was not known to do any injury to its inmates.
The Screech-Owl can hardly be said to construct any nest, but lines the hollow in which it rears its young with a few loose leaves, dry grasses, and feathers. The eggs are usually five or six in number; they are pure white, and nearly round. Their average measurement is 1.38 inches in length by 1.19 in breadth.
In regard to the distinctive peculiarities of var. maccalli, we are in possession of but little information. Its habits probably do not essentially vary from those of the common Scops asio, which it so closely resembles in other respects, and of which it is to be regarded as a geographical race. It was first taken by Mr. E. S. Holden, near Sacramento, and described by Mr. Lawrence as the Ephialtes choliba of Vieillot. It has since been found in other parts of California, in Northern Mexico, Arizona, and on the Rio Grande. It was obtained in Tamaulipas—where it is evidently rather common—by the late Dr. Berlandier, who had also procured its eggs. A single specimen of this Owl was obtained by Mr. A. Schott in Texas, and Mr. Dresser also obtained two small Owls which he doubtfully refers to this variety,—one near San Antonio, and the other in Bandera County. Lieutenant Bendire writes that it is quite common in the vicinity of Tucson, Arizona, though Dr. Coues did not meet with it. Dr. Kennerly observed it on Bill Williams Fork, in New Mexico. It was there found living in the large Cereus giganteus so common in that region, where it occupied the deserted holes of various kinds of Woodpeckers. It rarely made its appearance during the day, and then only to show its head from the hole, ready at any moment to disappear at the approach of danger. On one occasion it was observed among some very thick bushes near the water. It does not appear to have been met with by Dr. Cooper in California, where he refers all the Owls of this genus to the common asio. A single individual, referred doubtfully to this bird, was taken by Mr. Skinner in Guatemala. The eggs of this bird, taken in Tamaulipas by Dr. Berlandier, are of nearly globular shape, of a clear, almost crystal-white color, and measure 1.13 inches in length by 0.93 of an inch in breadth. As compared with the eggs of Scops asio they are much smaller, their relative capacity being only as five to eight.
The eggs of the var. asio vary greatly in size according to their locality. Those taken in Florida are so much smaller than those from Massachusetts as almost to be suggestive of specific differences. An egg from Hudson, Mass., taken by Mr. Jillson in April, 1870, measures 1.50 by 1.30 inches, while one from Monticello, Fla., taken by Mr. Samuel Pasco, measures 1.30 by 1.15 inches. Mr. T. H. Jackson, of Westchester, Penn., informs me that he has found a nest of this Owl containing six fresh eggs, on the 5th of April.
