To me, the bird's structure looks intermediate between that of a Hooded and a Bullock's Oriole. The tail seems strongly graduated, which is unusual. The photo gives the impression of there being a great deal of white in the wing panel, though I did not notice this in life. One of the clients specifically commented on how much white there was present.
The bird also somewhat resembles a Streak-backed Oriole, though the tail pattern seems off for that. In addition, the body was more extensively orange than is typical of northern populations of Streak-backed which tend to be most intensely orange around the head. I would enjoy getting feedback and insight from others regarding the identity of this peculiar bird.
