I need help Identifying this plant.
Not sure on this one. Additional photos and photos of flowers and/or fruits may help with ID.
I've enlarged photo for a closer look. With 75% assurance, it appears to be a weedy shrub called common buckthorn (Rhamnus cathartica). If you look at the very terminal ends of twigs, you may be able to see or feel a very small thorn about 1/8 inch long. If seen/felt, that's probably it.
Birds love the fruits, later making Technicolor messes because fruits are cathartic.
