Twite ring information

Received from Nick Wilkinson (RSPB Twite field worker)

Details of the colour-ringed twite seen at Fly Flats on 2 August (Red-White is a split colour ring):

R leg combinations:
RW/B; RW/O (in photo, poss the RW/Y listed); RW/R were all ringed as pulli in the same brood from a nest at Fly Flats in June 2008. The bird ?/G could also be from the same brood.

P/WR could be one of three birds ringed as pulli at other colonies in the south Pennines this year. Otherwise, it could have been mistaken as RW/P which was also a pulli this year from Fly Flats.

Twite pulli are being colour marked this year as part of our monitoring work for the Twite Recovery Project. The colour ringing is being undertaken to build up a population of marked birds to be able to monitor the number of breeding attempts made in a season by individual females. Birds are ringed with a unique combination (to allow individual identification) using a scheme of a colour above the BTO ring on the left leg and two colours on the right leg.

Thanks for these resightings.
