An individual with small white tips on the outer primaries, a medium sized white mirror on P10, black markings on the upper mandible and no moult of the head-feathers. The orbital ring is red and the iris is clear yellow. The red gonydeal spot doesn't continue on the upper mandible. P1 is still old, the secondaries appeared to be very fresh.
