Both nest in and around Frenchman's Meadow on the Stanford campus, where this was taken yesterday. I didn't get a good look at the bird after I took the picture. My amateur analysis below, based on grubbing around in Sibley and Jaramillo & Burke. What I usually look for is bill shape, Hooded being narrower and decurved. But that is hard to make out from the angle of this picture. Habitat favors Bullock's, but there's a fan palm in this meadow where Hooded have nested, and I've seen a Hooded in this live oak. So I go to the books, where I find: Behavior favors Bullock's, as it is mostly an insect gleaner, which is what this bird seems to be doing, while Hooded favors nectar. Bullock's has a shorter and more squared-off tail -- Hooded is longer and tapered. But I don't have a good sense of how long is long or how square is square. The mark that tilts it for me is that Hooded has solid yellow underparts, Bullock's has a gray-whitish belly contrasting with yellow breast, and usually has a white undertail coverts -- though they can be yellow. I can't see the whole belly, but everything I can see is yellow. So my guess is Hooded.
