Probably in your particular area, Mary Lee, Bitter Cherry (Prunus emarginata var. mollis) is more common, as you are either in the West Cascades Ecoregion or strongly influenced by it.Â In the south Willamette Valley (Willamette Valley Ecoregion, south part), Chokecherry (Prunus virginiana var. demissa) is fairly regular, and Bitter Cherry is nearly absent.Â If you map them together on the Oregon Plant Atlas you can see this elevational separation: http://www.oregonflora.org/atlas.php#
NOTE: This separation does not necessarily hold for other areas!Â See the map.

IÃ¢â‚¬â„¢ve understood that most of the wild cherry on the west side of the Cascades are Bittercherry, not Chokecherry. I this so and do birds like Bittercherry? I have some on my property and have not seen the birds eat it.
