WILDLIFE DISTRIBUTION AND OCCURRENCE
WILDLIFE SPECIES: Bubo virginianus | Great Horned Owl
GENERAL DISTRIBUTION :
The great horned owl breeds from western and central Alaska and central
Yukon east to Labrador and Newfoundland and south throughout North and
South America to Tierra del Fuego. Winter range is essentially the same
except for some migration to the southeast by northern populations,
usually in severe winters [14].

PLANT COMMUNITIES :
Great horned owls occupy a wide variety of forested habitats including
open coniferous and deciduous forests, mixed woods, orchards, second
growth forests, marshes, swamps, riverine forests, partially wooded
slopes, brushy hillsides, farm woodlots, and large city parks [13]. In
the western states great horned owls are often found in oak (Quercus
spp.) and pinyon (Pinus spp.)-juniper (Juniperus spp.) woodland [40].
In Idaho great horned owls are common wherever trees are large enough
for shelter [8]. In west-central Utah great horned owls are permanent
residents in pinyon-juniper woodlands [18]. In the Little Missouri
National Grasslands of western North Dakota, great horned owls were
observed in cottonwood (Populus spp.) woodlands but not in ash (Fraxinus
spp.) or juniper types. In this area, cottonwoods were lower in total
tree density but had higher canopy coverage than other types. In
cottonwood woodlands ground cover was 20 percent, dominated by grasses
[20]. In northeastern Wyoming great horned owls occupy riparian areas
dominated by eastern cottonwood (P. deltoides) and willows (Salix spp.)
surrounded by upland big sagebrush (Artemisia tridendata)-grassland
(primarily Agropyron) communities [33]. In Ohio, great horned owls
occur in virgin American beech (Fagus grandifolia)-maple (Acer spp.)
forests [1]. In the southeastern United States great horned owls are
common in baldcypress (Taxodium distichum) swamps and expansive, dense
cabbage palmetto (Sabal palmetto)-pine woodlands [13].
Andersen [4] listed the great horned owl as a secondary grassland
raptor; it sometimes breeds in grasslands but more typically breeds in
woodlands, edge communities, or partly open habitats.
