Carol,

IMO, it was likely a dark morph Red-tailed Hawk. RTHAs have a very broad
range of plumage, moreso among all of our raptors. WA does get a few
wintering dark morph Rough-tailed Hawks -- Sibley's estimates 10% of
Roughies W of the plains, although I would guess is closer to 1-in-20 (5%)
in WA -- and dark morph RTHAs are even more rare W of the Cascades. Also, a
dark morph Roughie would not have a visible belly band.

If you want to go down the rabbit hole of plumage variation in RTHAs,

BTW, I am a former West Seattle resident. We moved to Eburg eight years
ago. We love it over here, although I do miss my routine birding walks in
West Seattle.

Happy birding,
