Using Stephen Marshall's book, Insects: Their Natural History and Diversity, I have tentatively IDd this as Prochyliza xanthostoma. I was going to post it in the gallery but wanted to double-check the ID. On a bear carcass, 10 April 2011, West Virginia USA, 4.9 mm from the front of the eyes to the apex of the wing.

Many of these flies were present. Some, like the one in this picture, were on Skunk Cabbage, Symplocarpus foetidus. I couldn't tell if they were there because the plant smells like carrion, or because the bear carcass was only half a meter away. Probably both. But the male flies were skirmishing, seemingly defending territories on the plant. (I didn't see or photography any females, unfortunately.)

Lateral view, the fly posed on Skunk Cabbage. Wonderful shape of the head!
