Hi Louis,
I have not returned to try and get more images of the Oriole but my belief of it being a Bullock's Oriole comes from my researching six different
field guides on the bird and after seeing and reading the description and looking at the photograph of the adult female Bullock on page # 427 of the
National Wildlife Federation - Field Guide To - BIRDS - Of North America by.....Edward S. Brinkley, that the photograph on the bottom of that page
is so convincing in every detail that I truly believe it is indeed a Female Bullock's Oriole. If at all possible you can get access to this particular reference
guild, I think you can see why I have come to this conclusion. I will try again soon to get more images of the bird if it is still there. I do have a short video
of this bird in the tree where I took the still images but I don't know how to post it on line.
Your response is welcome........ Ken DiBiccari
