Funky Oriole

We saw a totally funky oriole today on the Glendalough field trip. There should only be Baltimore orioles here, but this one kind of looked like a hooded oriole (although not quite).

So, this bird is either a hybrid between the two, a second year male oriole who hasn't quite molted into his adult plumage, or sometimes female orioles attain male plumage as they grow older--is this just an old female?

Any thoughts.
