1cy October. SS and PP show a typically juvenile pattern with rather diffuse and slightly irregular dark bars in the outer vanes. The barring on the outer PP is in dark grey with the pale spots being dark buff in colour, less contrasting than in average adult birds. According to Ward & Feu (2006) juvenile P4 in British Wrens show 7-9 pale spots compared to 9-12 in adult P4. However, some birds (like this one) show spots that are less easy to count. Note that GC1-10 are all post-juvenile. [CP41538]
