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:
