It does look like Red Maple as Jim said. If you get a better pic that would be helpful. I've never messed wth Red Maple, but from cutting down and pruning many of them, I would use it as a core wood. I personally wouldn't try to make a self bow with RM, it's considered a softwood(I Think) and lacks strength.
The bark resembles Black Cherry a little bit, but it's real hard to tell. Black Cherry has dark coloured bark too. RM is grey. is the bark a medium grey color?
