pii Feb 14, 2018 06:57 PM Soaring Hawk Red-tailed has dark leading edges of the wings on the part of the wing closest to the body. Also note the breast is pale and the band just below is darker. The red tail is more certain with age. The Red-shouldered is smaller and has a banded tail. The back is more speckled. Throat is not pale. There is a red wash on the shoulders and the red on the underside is more prominent in the adult. On birds flying by, the wing beat of the Red-shouldered is faster & stiffer. It takes practice.
