For the Ragtag Daily Prompt: speculate.
We walked North Beach yesterday, 2 or 3 miles out starting at high tide 1:30 pm. There was a very large dead octopus on the beach. There were three bald eagles in the trees above and then more in flight, arriving for a chance at this meal. There was a pair of bald eagles flying in tandem and then this bird. The white wing tips are the clue. I can only find one very large bird in North America with the wings with white feathers at the ends, and it’s not an eagle.
Do you care to speculate? If I am correct, it is a long way from the Cornell Bird Lab map of where it is supposed to live.

Another vote for black vulture. The tiny head, the level wings while soaring (turkey vultures who live around me have red heads and a shallow vee). I love your photos so much!
many thanks! I am still learning the bird on the wing capture. Takes practice.
I’m certain it’s a black vulture. You’ve captured their gliding flight very nicely.
