I have now established the origin of one of the birds and attach details rec'd from Nick Wilkinson of the RSPB:
"Yes, the first bird is from our scheme. It was ringed as a nestling at Slaithwaite Moor nr Huddersfield, W Yorks, on 20th July 2010. It was seen at Titchwell reserve on 17th Oct and then again on 12th Nov, before returning back to Lincs at Humberston on 14th Nov, so is clearly moving up and down the coast.
We have been colour-ringing Twite in the south Pennines for the last three years as part of the Twite Recovery Project funded by RSPB and Natural England. This project is undertaking conservation work with landowners to halt (and eventually reverse) the decline in the south Pennines Twite population. The birds have been ringed as part of our monitoring work to assess the effectiveness of the recovery project. We have used unique colour-ring combinations so that we can collect data on the number of nesting attempts made by individual females in a single season. Records of these birds outwith this, however, are valuable for further understanding their movements and survival."
If anyone sees any further colour-ringed Twite, they can be reported to Nick at
nick.wilkinson@rspb.org.uk.
