    There is plumage variation in Oregon Junco from four sources: subspecies, age, sex, individual. Your bird is almost certainly an immature, given the brown crown, but any certainty is ruled out by the quality of the photo. IMO, that photo quality also rules out being able to sex the bird if it is an immature.

    Oops. Forgot photo links.




    I thought about adding that to my post that it's an immature, but I checked Sibley and it shows that the females also have brown crowns. I know that eye color is the other factor in determining age, but that isn't visible here. Is that true that adult females have brown crowns too? Or is it just that the immatures have a more extensive brown crown?

    That's what Connor is suggesting. I know almost nothing about Tule, so I beg off from providing an ID. However, I do see the differences Connor illustrates. Beware, though, that there is substantial size difference in all goose species, some related to subsp, some to sex, and a lot to individual variations, with young-of-the-year generally weighing less, which can impact impression of overall size.

    Yeah I realized that then couldn't edit it ?

    I think the bill is heftier than an AMGP, and I remember that @Melierax said something about the undertail coverts being a good field mark. Don't want to misquote...

    Yep I said that. Only works for adult birds. The bill on this one looks pretty slight but the second photos definitely doesn't look like golden-plover to me. Just looking at Sibley's, the top of the tail in BBPL is starkly black and white whereas in golden plovers it's kinda buffy. Not sure if that's reliable but based on that this bird is a BBPL.
