Death of an oriole

Upon looking at the branches, I notice a Black-naped Oriole. It's mouth open..



This is about 15-20 feet on top of a tree, I notice it is not moving. The position on the branch is like leaning on the branch. Is it sick or dead?



Then another oriole perched beside it.. It look around for a while silently, then flew away as if saying goodbye to a comrade. This is when I felt the oriole was truly dead.



Sorry for the bad pics, record shot, no flash, not even +2 ev compensation. and heavily cropped.
