Juvenile. A very young bird still being feed by the adults (but moved around in the forest with the adults).
Note the whitish tips to greater coverts - these are probably seen only for a very short period, when the bird is very young. I have never photographed this before. The juveniles I have pictures of only shows narrow white edges on (some) remiges (like this bird).
I have more pictures of this immature bird taken on the same day.
