This
is the first record of this young male, one of this season’s youngsters, ringed
by Tony Cross as one of a late brood of two, at a site about 7 km south of
Llansantffraed. Interestingly, he was raised by a 21 year old colour-ringed
female - our oldest productive female to date. His brood sibling sister was
recorded up at the northern communal roost near Borth in August and October –
great to know trhat both of this brood fledged
successfully.
The
colour-ringing is all part of a long-running study of choughs in mid + North
Wales by Tony Cross + myself, during which over 5,000 individuals have been
marked over the past 26
years, with life histories recorded for many of these birds, shedding light on
their movements, social + nesting behaviour, longevity
etc.
