Thanks Dave, good call. Could be either, in both cases in non breeding plummage. I'm inclined to think Javan but will try to get ID when I am back at CMZ, although there was no ID sign last time.
Yeah, I am inclined to think Javan too as it looks a lot like the one I have seen in the past; but as the two species look almost identical when out of breeding plumage I could not rule the other taxa out.
