This is a hybrid - most likely Baltimore X Altamira called a "Smudgy" by the park guides.

This looks like the same bird that David Dauphin posted on his web-site.

"I have posted photos of the Audubon's x Altamira Oriole hybrid that was
taken at Bentsen SP-WBC in late March, this year.

To view them, go to "Jan's Photos", via my webpage, then follow the links to
"David's LRGV Bird Photos" album.
