Sculthorpe Moor - 21st September 2022

 Only six species today. Other than residents there were only 4 Chiffchaff, one being a female that bred close to net one and was now finishing a full primary moult before completely losing her brood patch (BP5). Twenty five birds were processed in all.

The BTO has recently stated that only 13% of birds are reported with details of moult. Ringers often record the stage of wing moult but do not record other stages of moult. We are pleased to be able to say that we always record moult throughout the year. The aged 3 Blue Tit below was coded 'P' as post-juvenile moult is still in progress. Further to that, an alula score of A0 (both old) and 3ogc (retained old greater coverts)  was also recorded.

Juvenile Blue Tit

Long-tailed Tit, moult code 'E' ending, aged as a 2 (Year of hatching unknown)
 as all birds do a full primary moult
