Re: American × Black Oystercatcher Hybrid (Haematopus palliatus × bachmani) - Cabrillo Nat'l Tide Pools

On all those traits that Jehl analyzes that can be seen in the 3 photos, the bird is likely squarely in the pure American Oystercatcher category.
Hard to see if the undertail coverts are pure white, or have tiny black streaks.
From what little one can see of the wing stripe, that also looks good for American.
Upperwing and uppertail photos still needed.
