Yes, exactly!
In our Illinois oak-hickory forests, we have three principal vines, which all can grow far up into the canopy trees: Virginia Creeper, Poison Ivy, Wild Grape (Vitis riparia and perhaps other species). That's the place to grow your berries, if you want your seeds distributed by air! Arboreal mammals--like raccoons, opossums, maybe squirrels--probably take some of these fruits when they grow near branches that can support them. Some of the fruits will fall to the ground, of course, and be taken by any scavenger that finds them, as well, but for the most part these vines are bird food factories. And so there's something you can be 99% sure about
: Wherever you see one of those vines growing, a bird pooped there!
