WILDLIFE DISTRIBUTION AND OCCURRENCE
WILDLIFE SPECIES: Otus asio | Eastern Screech-Owl
GENERAL DISTRIBUTION :
The eastern screech-owl is found in eastern North America and
northeastern Mexico. Its range extends across southern Saskatchewan,
southern Manitoba, northern Minnesota, northern Michigan, southern
Ontario, southwestern Quebec, and Maine; south through eastern Montana,
eastern Colorado, and Texas to central Nuevo Leon, eastern San Luis
Potosi, and southern Tamaulipas; east to the Gulf Coast and southern
Florida [1,27]. At the western edges of its range, it appears to be
confined by the eastern front ranges of the Rocky Mountains in Wyoming,
Montana, and Colorado [1,13,22].
Distribution of subspecies is as follows:
Rocky Mountain screech-owl: Southeastern Saskatchewan, southern
Manitoba, eastern Montana, and the Dakotas south to eastern Wyoming,
western Nebraska, western Kansas, and northeastern Colorado. Possibly
also breeds in central Alberta, but these birds may be western screech-owl.
Hasbrouck's screech-owl: Central Kansas to Oklahoma and Texas.
Texas screech-owl: Lower Rio Grande to the southern border to Tamaulipas.
Southern screech-owl: Minnesota, peninsular Michigan, southern
Quebec, and southern Maine south to Missouri and northern parts of
Mississippi, Alabama, and Georgia.
Florida screech-owl: Florida and the Gulf Coast west at least to
Louisiana and north to Arkansas [18].

PLANT COMMUNITIES :
The eastern screech-owl occupies a wide variety of habitat types [29].
It is commonly associated with open woodlands of oaks (Quercus spp.),
maples (Acer spp.), and hickories (Carya spp.); it is also found in pine
(Pinus spp.) forests and plantations, mixed woodlands, orchards, and
forested wetlands [28]. At the northern and western edges of its range,
the eastern screech-owl occupies riparian woods dominated by hardwoods
including boxelder (Acer negundo), green ash (Fraxinus pennsylvanica),
and bur oak (Quercus macrocarpa) [23]. In South Dakota eastern
screech-owls were found in riparian woods dominated by eastern
cottonwood (Populus deltoides) and willows (Salix spp.), hardwoods
dominated by green ash, boxelder, American elm, and bur oak, and
shelterbelts. Siberian elm (Ulmus pumila) is a common shelterbelt tree
in South Dakota and is used by eastern screech-owls [12]. In Kansas
eastern screech-owls were also observed in shelterbelts [26]. In New
England, eastern screech-owls are found in aspen (Populus spp.), paper
birch (Betula papyrifera), northern hardwoods, red maple (Acer rubrum),
balsam fir (Abies balsamea), eastern hemlock (Tsuga canadensis),
northern red oak (Quercus rubra), eastern white pine (Pinus
strobus)-northern red oak-red maple, and eastern white pine communities
[11]. In South Carolina on the Coastal Plain, eastern screech-owls were
observed in pine and hardwood stands. The managed pine stands were
mostly longleaf pine (P. palustris) and loblolly pine (P. taeda).
Hardwood stands were dominated by gums (Nyssa spp.), baldcypress
(Taxodium distichum), oaks, or red maple [17]. In Louisiana eastern
screech-owls were found in mature mixed bottomland hardwoods dominated
by water oak (Q. nigra), pignut hickory (Carya glabra), American elm
(Ulmus americana), and sugarberry (Celtis laevigata). They also
inhabited cottonwood plantations and riverfront hardwoods dominated by
sweet pecan (Carya illinoiensis), water hickory (C. aquatica),
sugarberry, and waterlocust (Gleditsia aquatica) [24].
