Strix nebulosa Yosemitensis
This individual shows the key characteristics of immature Harlan's Red-tailed Hawk, which are overall dark coloration mottled with white, banded outer primaries (unlike any other Red-tail morph or subspecies), primaries that don't reach the tail tip and a gray-cream colored (evenly-spaced) wavy-banded tail.
Dark-morph Harlan’s Red-tailed Hawk. - (Buteo jamaicensis harlani) it was also being chased by a red tailed hawk that was right above me.
Found dead beside a little traveled dirt road, appeared to have been killed by a predator, perhaps a Great Horned Owl?
Died from building window strike
