Complete moult not started: P1 still present.

Bird in 4CY, but overall very retarded plumage. Scap region still not a completely grey saddle, but intermixed with immature feathers. All wing-coverts and tertials (except for innermosat GC and MC) with barred pattern, not adult-like grey. Inner primaries with brown hue on outerwebs mostly, even some vermiculated patterns on P3-P4. Sub-terminal patterns on P4-P6 rather dark brown, not blackish as commonly found in 4CY birds. Much black in tail, no mirror on P10 and only very small pale tips on brown, outer primaries.
