), raccoons (Procyon lotor), bassarisks (Bassariscus astutus), skunks, snakes, crows (Corvus ssp. Male and female Eastern Screech-Owls are similar to one another in all seasons. The Screech Owl is a very small species with a size of no more than 10 inches in height. An eastern screech owl tends to frequent areas in its home range where it hunted successfully on previous nights. This species has two color morphs, one with gray plumage and the other with rusty-red plumage. Eastern Screech Owl Megascops asio Order: Strigiformes Family: Tytonidae Overview While many facilities recommend screech owls as an “easy” or “beginner” owl, it is important to be extra vigilant with these small species that are more easily, albeit unintentionally, dominated. [5][6] They have either rusty or dark gray intricately patterned plumage with streaking on the underparts. The owl spends the day roosting in holes or in dense cover, becoming active at dusk. Their voices are unmistakable and follow a noticeably different phrasing than that of the western screech owl. The Heroes that Were Pigeons: The Smart “Rescue and War” Pigeons Five subspecies of Eastern Screech-Owl are recognized, varying in color, size, and voice. Chinese: ???? Adults range from 16 to 25 cm (6.3 to 9.8 in) in length and weigh 121–244 g (4.3–8.6 oz). The female does most of the incubation (brooding of the eggs) which lasts about 26 days to hatching. [9], In the closely related western screech owl (Megascops kennicottii), no color morphs are known; all owls of the western species are gray. They will also hunt small mammals, such as rodents, bats, shrews up to the size of rabbits; and birds ranging from chickadees, sparrows, warblers up to the size of a Ruffed Grouse (which are heavier than the screech owls). Small birds such as chickadees (Poecile ssp. Rusty birds are more common in the southern parts of the range; pairings of the two color variants do occur. Five subspecies are typically treated for the eastern screech owl, but the taxonomy in the species is considered "muddled". A 9-year study comparing the breeding success of eastern screech owls nesting in natural cavities and nesting in nest boxes showed that the fledging rate was essentially the same, although in some years, up to 10% more success occurred in the natural cavities. Despite their diminutive size and apparent ease of handling, in order to provide good welfare,… While the gray morph provides remarkably effective camouflage amongst the bark of hardwood trees, red morphs may find security in certain pine trees and the colorful leaves of changing deciduous trees. The feet are relatively large and powerful compared to more southern screech owls and are typically feathered down to the toes, although the southernmost populations only have remnant bristles rather than full feathering on the legs and feet. This is because they have a red color at one point in their life and then gray at another. Screech owls typically nest in cavities of deciduous trees, such as oaks, elms, maples, sycamores, willows, apples and pines. [3] From one to six eggs have been recorded per clutch, with an average of 4.4 in Ohio, 3.0 in Florida, and 4.56 in the north-central United States. On occasion, they will also take earthworms, reptiles (small snakes, lizards even baby soft-shelled turtles), amphibians (frogs, toads, etc.) The eyes range in color from greyish-yellow to bright yellow. The eastern screech owl (Megascops asio) or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. They usually only produce one clutch a season; but may produce a second, if the first clutch is lost. An adult Eastern screech-owl is usually only between six and nine inches in length. The head is large and round, with prominent, wide-set ear (feather) tufts.

[21] While much of their insect prey can weigh only a fraction of a gram, their largest prey, such as adult rats and pigeons and juvenile rabbits and gamebirds, can weigh up to at least 350 g (12 oz). The females tend to be larger - with an average length of 9.2 inches (23 cm), a wingspan of 22 inches (56 cm) and weight of 7.3 oz (208 g). They are also capable of catching insects or small birds in flight. Please contact them directly with respect to any copyright or licensing questions. The smaller males average 8.2 inches (21 cm) in length, have a wingspan of about 21 inches (54 cm) and weigh about 7 oz (200 g). They also produce a monotone purring trill lasting 3–5 seconds. Due to the ferocity and versatility of their hunting style, early authors nicknamed eastern screech owls "feathered wildcats". ), lizards, baby soft-shelled turtles (Apalone ssp. ), swallows, sparrows, and warblers are the most common avian prey, and such species are normally caught directly from their nocturnal perches or during nocturnal migration. As is the typical division of labor in owls, the male provides most of the food while the female primarily broods the young, and they stockpile food during the early stages of nesting, although the male tends to work hard nightly because many nestlings often appear to live almost entirely on freshly caught insects and invertebrates. Jumping mice (Zapus ssp. Your use of this website indicates your agreement to these The wingspan can range from 46 to 61 cm (18 to 24 in).

Of vertebrates taken in the nesting season, 65% were birds (of about 54 species), 30% were mammals (11% meadow voles; 8% each of house mice and deermice (Peromyscus ssp. [16], During the breeding season, large insects are favored in their diet, with invertebrates often comprising more than half of the owls' diet. They may use the abandoned nests of other birds, such as woodpeckers. [7][8], Two color variations are referred to as "red or rufous morphs" and "gray morphs" by bird watchers and ornithologists. Eastern Screech Owls are compact in size and shape, measuring from 6.3 - 9.8 inches (16 - 25 cm) in length, including the short tail, and weighing about 4.3 - 8.6 oz (121 - 244 grams). Heterodon ssp. The eastern screech owl's call is a tremolo with a descending, whinny-like quality, like that of a miniature horse. [3][18] Most prolific by far of the eastern screech owl's avian predators is the great horned owl, which can destroy up to 78% of a local population, but locally, Cooper's hawks and barred owls are almost as serious of a threat. tree frogs and northern leopard frogs (Lithobates pipiens)), toads, newts, and salamanders are also preyed upon. The male is responsible for feeding the nesting female. It is only provided for educational and entertainment purposes, and is in no way intended as a substitute for [20] Due to meeting the needs of their nestlings, eastern screech owls frequently consume less per day during summer than they do during winter. The plumage below is whitish patterned with streaks, offering them a perfect camouflage against the tree bark. The facial disk is a paler cinnamon; the upper plumage is rusty colored. Much of the variation may be considered clinal, as predictably, the size tends to decrease from north to south and much of the color variation is explainable by adaptation to habitat. Females do most of the incubating and brooding, but males also occasionally take shifts.
