Most years I will post something about a Sand martin being recaught in France, Spain, Senegal or Sussex. These are always nice but of relatively little value beyond saying how quickly Sand martins leave the UK. Incidentally for getting to France it's fairly quick with the first broods almost certainly heading south now and most juveniles being through France within a month of fledging.
Just occasionally we have birds recaught more locally but on passage. One such bird was D335186 which was ringed near Kirkby Lonsdale in June 2013 as a breeding male. On the 25th July 2014 it was caught at Walney bird observatory, presumably fattening up for the migration to West Africa although could have been breeding closer to Walney in 2014. On the 9th July D335186 returned to Kirkby Lonsdale at the same colony as it was in during 2013. This, more or less, confirms it was on passage at Walney and adds another small bit of information into the puzzle about what Sand martins do between breeding and migrating.
