Is this Poplar?

Not sure what that is might be some sub species of poplar but its not tulip poplar. people here call it birch or water maple but I dont think thats right either.

I was thinking the same thing. The tulip poplar which we have a bunch of around here has a thicker rough bark that looks more like oak then that. That looks smoother similar to a birch as you said.
