Possibly 2 individuals, as I saw another at the further large pond with the majority of peeps, but this could’ve easily been the first bird, as that one flew a couple times and didn’t see it on way back."

- Comments: "The group chased the bird up Villa Creek Rd where it was relocated here within a few minutes, 35.476999, -120.977357 From this location the group saw it flying high overhead. By the time I arrived a few minutes later it was circling and drifting eastward. A few poor photos were taken. Distingished from TUVU by all black underwing and very light gray primaries, tail was noticably shorter than TUVU. No red was visible on the head. The bird flew farther east and was not seen again during this outing."

Seen mostly from the underside as the vulture was soaring overhead. Overall black; dark featherless head; dark bill; white, black-tipped finger-like outer primaries that appeared somewhat translucent; short, square tail; light-colored legs; non-rocking gliding flight with very few flaps; wings were not held in a dihedral (V) shape as with Turkey Vultures, but rather horizontally straight across.

- Comments: "Refound continuing bird (Luke Jensen 07.31.25) soaring in an easterly direction above Villa Creek Road at approximately (35°28'54.7"N 120°58'38.5"W). The vulture was gaining altitude quickly on wide, flat wings. Despite the altitude, its black head, short tail, distinctive white legs and feet and "white wing-mittens" comprised of white primaries were easily seen. Bird was in view for approximately 12-15 minutes but was eventually lost to the altitude and easterly flight path."

- Comments: "Observed continuing bird (Luke Jensen 07.31.25) from vantage point on south end of main Villa Creek beach (35°27'29.1"N 120°57'54.7"W). First spotted by KH about 1.2 miles NW of our position, the bird was starting it's ascent near and above hillside here (35°28'22.8"N 120°58'38.8"W ). Distinguished in flight from developing kettle of Turkey Vultures by its repeated, shallow and relatively rapid wing beats this bird's signature outer wing "white mittens" were easily seen as the morning sun chased off a stubborn marine layer. As the vulture disappeared behind some hills along Villa Creek Road we headed for our vehicles to get closer as it headed east."
