Mark,
You may well be correct I’m calling this bird as a hybrid. However, it might be
an aberrant plumage.

P.S. if the bird is a hybrid, as you suggest, Bullock’s would be one parent; I
have no idea as to what the second parent might be.

I visited The Post park south of Marathon again this morning. In addition to
the continuing White-eyed and Yellow-green Vireos I photographed a hybrid (?)
oriole. I suspect this bird has been reported as a Hooded, but it isn't
that. When I first saw it I thought it was a Streak-backed, but doesn't fit
that species either. It has a streaked back, but it is largely black. The
wings have a lot of white in them suggesting Bullock's as one of the parents,
but it also has orange shoulders. I am struggling to even come up with a
second species that could be involved. Interesting bird for sure. I have
places three images on my Flicker page at:
