Over 100 meat-eaters

For those of you who enjoy watching very large flocks of meat eating
birds.....this would've been a treat for you. Over 100 vultures? or
Eagles? flew Southwest of North Yelm at 5:30 PM today.
They formed two circles and flew at a high altitude enjoying the air
currents, just before it starting raining at 5:40PM.

[I am oftentimes directionally challenged - Northwest
NOT Southwest.]

Noted not likely to be vultures (was told by tweet vulture exp. would be unusual)
Eagles do not flock, either.
No outstretched necks or trailing legs noted w/re: Sandhill Cranes

Very large bird much like an Eagle/Ospry/Vulture.
Flap, flap, glide, soar.
Wingtips with fingerlike projection of feathers like Eagles/Ospry/Vultures.
