The Midwestern subspecies (Bonasa umbellus
mediana) existed in the northwestern region of the state while the Appalachian subspecies (Bonasa umbellus
monticola) occupied the southern two-thirds of Indiana (Aldrich 1963).
Coniferyl benzoate in quaking aspen (Populus tremuloides): Its effect on energy and nitrogen digestions and retention in Ruffed Grouse (Bonasa umbellus
Impact a court terme d'une coupe avec protection de la regeneration sur la gelinotte huppee (Bonasa umbellus

In winter, the staminate flower buds of quaking aspen (Populus tremuloides Michx.) are an important food source for Ruffed Grouse (Bonasa umbellus
L.) in North American deciduous and boreal forests (Gullion 1966, Vanderschaegen 1970, Svoboda and Gullion 1972, Doerr et al.
A study on radio-tracked ruffed grouse Bonasa umbellus
concluded that mortality due to hunting was at least partially if not completely additive (Small et al.
(6) Teratomas have been documented in a variety of mammalian, reptilian, and avian species, including an African grey parrot (Psittacus erithacus erithacus), several species of ducks (Anas species), chickens (Gallus domesticus), domestic geese (Anser anser domesticus), ruffed grouse (Bonasa umbellus
), old squaw (Clangula hyemalis), and Canada geese (Branta canadensis).
Other common occurrences in the Michigan study were snowshoe hare (Lepus americanus), woodland deer mouse (Peromyscus maniculatus), muskrat, red-backed vole (Clethrionomys gapperi), grouse (Bonasa umbellus
), and apples (Pyrus malus) (Ozoga and Harger 1966).
However, satisfaction was not correlated with hunting success for ruffed grouse (Bonasa umbellus
; r = 0.115, 0.10 < P < 0.20) or spruce grouse (Falcipennis canadensis; r = 0.136, 0.05 < P < 0.1).

Nonungulate prey present throughout the study area include Beaver (Castor canadensis), Raccoon, Mountain Beaver (Aplodontia rufa), Porcupine (Erethizon dorsatum), Snowshoe Hare (Lepus americanus), Opossum, Ruffed Grouse (Bonasa umbellus
), Blue Grouse (Dendragapus obscurus), Turkey (Meleagris gallopavo), Canada Goose (Branta canadensis), and several species of domestic livestock and pets.
They harvested ruffed grouse (Bonasa umbellus
, 9.3 / 100 hunting days) and spruce grouse (Dendrapagus canadensis, 4.3 / 100 hunting days) as well as moose (0.4 / 100 hunting days).
For example, the trigeminal nerve is responsible for the detection and reduced intake of coniferyl benzoate (a dominant PSM in quaking aspen Populus termuloides) by European starlings Sturnus vulgaris and may explain regulated intake of that PSM by ruffed grouse Bonasa umbellus
(Jakubas & Mason 1991).
This paper updates the distribution and relative abundance of ruffed grouse (Bonasa umbellus
) in Ohio.
Ruffed grouse Bonasa umbellus
at one location at Lake Superior, Minnesota, USA, allowed a photographer to follow them closely, whereas the species, even within this region, was viewed as particularly wary (Gullion 1989).
