Muscicapa striata - autumn

Spotted Flycatcher / Grå flugsnappare

AGE - BEST CRITERIA:

Moult contrasts are present in both 1cy and 2cy+. However, the extent of the moult is rather restricted and sine the juvenile feathers (e.g. GC and tertials) are easily recognized, ageing of Spotted Flycatchers in autumn seldom renders any problem.
 
1cy: 
  • Juvenile GC are easily reckognized by being rather fresh, and by having pale buffish edges that broadens to a paler tip. Most individuals show 0-1 inner post-juvenile moulted GC with somewhat darker and more glossy centre and very fresh olive-brown edges/tips. 
  • Juvenile tertials are rather similar to juvenile GC, showing a brownish centre and broad warm buff edges widening at the tip. 1cy does usually not include any tertials in the post-juvenile moult, but an odd moulted post-juvenile tertial is reckognized by being more fresh and dense, having a darker greyish centre and olive-brown edges (and lacking the wider pale tip).
  • Juvenile PC are fresh, often showing narrow pale tips.
  • Juvenlie RR are fresh and slightly more pointed than adult feathers. A few upper tail-coverts are often retained juvenile, showing distinct pale buff tips.
2cy+:
  • GC are worn pre-breeding feathers (lacking fresh buff edges and wide pale tips), and some individuals show 1-2 inner moulted post-breeding GC with somewhat darker and more glossy centre and very fresh olive-brown edges/tips.
  • Pre-breeding tertials are worn brownish-grey, often lacking (worn off) pale edges. Many individuals have included some or all tertials in the post-breeding moult. Such feathers are very fresh and show a dark greyish centre and olive-brown edges (and lacks the wider pale tip seen in juvenile tertials).
  • PC (pre-breeding) are rather worn.
  • RR are usually uniform pre-breeding, but many are still in rather good codition (likely moulted during late winter). A few adult may have included 1-2 RR in the post-breeding moult.
1cy September. GC1-9 are juvenile while GC10 (partly hidden under the scapulars) is post-juvenile. Note the typical juvenile pattern with rather fresh buff edges and pale buff tips. [CV06213]
2cy+ August. Note the worn pre-breeding GC1-9 and the fresh post-breeding GC10. MC and LC also consists of both worn (pre-breeding) and fresh (post-breding) feathers. [CP46555]
1cy September. Uniform and typical juvenile tertials, fresh with brownish centre and buff edges and tips. [CV06291]
2cy+ Augusti. Note the worn pre-breeding tertial in contrast to the two longer fresh post-breeding ones (contrasting well to the pre-breeding S6). [CP46555]
1cy September. The juvenile PC are fresh with pale tips during early autumn. [CV06213]
2cy+ August. The pre-breeding PC are rather worn, lacking pale tips. [CP46572]
1cy September. Juvenile rectrices are less dense and show more narrow tips than adult ones. Note also the still juvenile upper tail-coverts with broad pale buff tips. [CV06291]
2cy+ August. Dense feathers with blunt tips. Note that the RR are in rather good condition, despite being pre-breeding. Perhaps this is best explained by being moulted during late winter, just before spring migration. [CP46572]
