Very interesting bird: age provenance 3CY bird (2nd cycle / 2nd winter) with very bold white tips on primaries. Probably in active moult in primaries, reflected by the very adult-like upperparts and much white in tail. In this respect approaching moult sequence and timing of nominate fuscus, but of course upperparts way to pale grey, classic for graellsii birds.
