Banders Round up

I banded the attached male Rufous Whistler at home on Sunday 2^nd Aug which appears to be an anomalous bird when compared to the Banders Guide. The gape is a very pronounced yellow i.e. indicating juvenile status while at the same time showing the distinct male black upper breast band. The Guide indicates or infers the black band does not appear until >3 years and the yellow gape and pale horn upper/lower mandible base are the traits of a juvenile or year 1 bird. There was no streaking on the upper or lower breast area. I would like to hear your views on the age of this bird.
