First cycle in preformative molt. Apparent molt limit on greater coverts.
Détails de l'observation
Continuing (since 14 Sep), very well documented (see numerous checklists by others) first cycle bird in preformative molt. Bird still shows a few scattered, but generally dull dark flecks (juv feathers) on throat and sides of upper breast, and in pale crown stripe and pale supercilium. Also, the outer (6?) gr coverts appear darker centered and fresher than the browner maybe more worn inner 3 gr coverts (molt limit?). See also Gwen Baluss' excellent photo (ML623740055, 14 Sep) documenting active molt (apparently unsymmetric?) in the tail feathers.
