Phil Jackman forwarded these images of a leucistic juvenile Starling present in his Kettering garden this weekend. While generally uncommon, leucism (really a lower concentration of melanin) in juvenile Starlings has been recorded on numerous occasions and invites confusion with juvenile Rose-coloured Starling which, however, has a largely yellow bill (especially at the base) and pale lores.
Also, this individual has already begun its post-juvenile moult, which commences with the wing feathers – in this case all the juvenile greater coverts, except the outer two, have been replaced.
This feather tract is again different to the equivalent plainer feathers of Rose-coloured. It’s interesting that these first-winter feathers are apparently normal, suggesting the bird’s leucism (lack of melanin) is age-related.
Many thanks to Phil for the images of this interesting bird.
