Geoffrey, very interesting about the eye colour, though it’s the black eye
(ear?) stripe (plus the rufous edged-tail not visible on these photos) that I
would normally use to separate both the juvenile and adult H B-C from the
Shining B-C, especially as the adult depicted seems to me very barred compared
with many you see.
I’m assuming it’s this year’s young as well as recently taken? If so
we’ll keep a keen look out for them during the nest workshop on 16 November, as
we more often see/hear the Shining, but very little indication of
breeding.
