Classic wing-tip pattern:
- Long white tongue on P10, in combination with full sub-terminal band.
- No mirror on P9.
- Black on P9 hardly meets greater primary coverts (only at very edge of the feather).
- 'bajonets' (long black points at outer edge of feather) on P6-P7.
- W-shape on P5 (only in right wing).
