[QUOTE="P.Sunesen, post: 3605575, member: 100020"] Our bird is finishing the post juvenile moult. In comparison here a bird in pure juvenile plumage where the dorsal side has spots on every feather. [url]https://www.google.dk/search?q=bluethroat+juvenile&prmd=ivmn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjGke-ty-fVAhWKNJoKHejlBv8Q_AUICSgB&biw=1024&bih=672#imgrc=CL531gruGixuqM:[/url] And here the ventral side (also more spotted than our bird, which has grown uniform, first winter feathers practically everywhere but on the head). [url]https://www.google.dk/search?q=bluethroat+juvenile&prmd=ivmn&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjGke-ty-fVAhWKNJoKHejlBv8Q_AUICSgB&biw=1024&bih=672#imgrc=-k2sBvnsburATM:[/url] These two examples (of pure juveniles), also show a richer colour to the juvenile feathers than our bird whose remaining juvenile feathers are quite bleached. It does take some time for such an advanced stage of moult to be reached. And it does take some time of exposure to sunlight to cause the remaing juvenile feathers to fade this much. In sum a typical bird from mid/late August, markedly different from a recently fledged, pure juvenile from June/July. It will soon be ready to migrate, in synch with the majority of the birds of the year. Peter [/QUOTE]
