Smooth bluish twigs just like that one

Did you want an ID, or are you just wondering if Smooth Sumac is a tree or a shrub?

The question was ’which species is it?’ OP calls it a tree so has presumably already made that decision.

It was a joke, Embo gets it

Rhus glabra aka Smooth Sumac

Lmao, thanks! Smooth Sumac (Rhus glabra) was just my first guess off the top of my head, but I really wasn't sure given there's also Rhus lanceolata, coppalinum, etc around here...
