Chokecherries are a common wild shrubby tree in much of the West. Utah, Idaho, Wyoming, and Colorado have them in abundance. The fruits provide food for many species.
When I lived in Logan, Utah back in the '70s, we could walk around town in late fall catching drunken robins, cedar waxwings, evening grosbeaks, and others that were over the line from too many fermented chokecherries.
The Moose Wilson road in Grand Teton National Park is lined with chokes on the northern end, and as such, is a great place to view both black and grizzly bears in the fall.
I've got an opened jar of chokecherry syrup in the fridge right now.
The trees are festooned with fragrant blossoms in late spring, but often there are no honeybees working them, something I find odd.
