Virginianus

Evolution and systematics Great horned owl (Bubo virginianus) sleeping during daytime in a hollow tree The systematic placement of owls is disputed.

For example, environmental degradation from white-tailed deer ( Odocoileus virginianus ) in the US alone has the potential to both change vegetative communities through over-browsing and cost forest restoration projects upwards of $750 million annually.

Similarly, both eagle species have been recorded, via video-monitoring, to feed on gut pills and carcasses of white-tailed deer (Odocoileus virginianus) in remote forest clearings in the eastern Appalachian Mountains without apparent conflict.

They grow from a permanent outgrowth of the frontal bone called the pedicle. and can be branched, as in the White-tailed deer ( Odocoileus virginianus ), or palmate, as in the Moose ( Alces alces ).
