Additional sightings were made in San Mariano, Isabela. and Baggao, Cagayan Valley It It is found in moist lowland forest up to 440 masl. It is threatened by habitat loss and hunting.

The Isabela oriole is commonly confused with the much more common white lored orioles and black naped orioles. It is differentiated by its extremely large bill grey bill, uniform olive yellow plumage and lack of white on its lores. The Isabela oriole is most closely related to the white lored oriole.
