this is a native grapevine, grandfather used to call it a Birdseye grape.
I’m sure that this can be called birdseye grape – it is usually called Summer Grape – Vitis aestivalis. The deep leaf lobing is characteristic, but the leaves are sometimes only shallowly lobed. The leaves are loosely thin-woolly, and the ripe grapes are edible. The background looks like a wax myrtle shrub, by the way.
I hope this helps.
