It is a good year for Pied Flys in our area this year with reports of a marked increase over 2013 especially in the more upland woods. Productivity has been excellent with good brood size and so far only two nests have failed.
Our re-trapping Adults for Survival study area comprises 13 woods in the upper Lune valley and its tributaries. Several returns are yet to come in and some late nests still have nestlings to ring but to date I have received details of 294birds. These break down to 29 new adults 215 nestlings and 50 re-traps or controls of adult birds.
A quick analysis of the re-trap data shows some interesting differences as one might expect between birds ringed as adults and those ringed as nestlings. Of the returning adults 16 were re-trapped in the same wood as previous years and only four moved to another wood. However one female moved 17km from its nesting area last year. Of birds ringed as nestlings and returning to breed for the first time 13 returned to the wood where they were born but 22 moved to another wood. This later figure may increase when the Ringing Office forwards any controls outside our area.
