I'd be really cautious about this one ... I've seen both species in the Yucatan, and found it really tricky to distinguish one from the other.
In New World Blackbirds (Jaramillo & Burke) there is an illustration of the igneus race of Hooded, which looks a lot like this. The caption reads (in part): "Yucatan region of Mexico and Belize: This is the brightest orange race." This same book also says, of Orange Oriole, "note that unlike Hooded Oriole, the slender bill of this species is straight." I recall that, for us, a really good look at the bill was the only way we could tell them apart. (This bird's bill does look a bit a bit curved to me, in the flight picture.)
Wing bars make it look like a hooded oriole. I had one in Mexico, it took me 10 minutes of walking around pyramids with book in hand, only to find it was not a lifer bird. I only came home with less than 20 birds my only Mexico trip.
