Blimey, thanks Terry!!
Yes, fondly remember those days! Before the nightmare of Health and Safety too - as you can tell by the angle of the ladder! Think those photos were taken in 1991, the first year we colour-ringed Choughs in Ceredigion. Most of them ended up on Craig-yr-Aderyn (Bird Rock) near Tywyn. Think that was where Hywel took the big flock photo. Highest count we had there was getting on for 80!
