By March, the plumage of some Cooper’s Hawks is especially faded and the tawny tones typically seen throughout the head and nape can be bleached to whitish. Sun bleaching/feather wear can produce, in some cases, a streaky aftermath and a combination of potentially misleading ‘false fieldmarks.’ The strong eyebrow (supercilium) on this large Cooper’s Hawk could certainly encourage the thought of Northern Goshawk as a possibility 😉
Good birding.
