Every year in July and August, we (Sorby Breck Ringing Group), ring Swallows coming in to roost at the Derbyshire Wildlife Trust's Avenue Washlands reserve near Chesterfield, Derbyshire. (see here)
Last year we ringed on several occasions, catching over 400 birds, and today I received an email from David, to say that one of the birds ringed by my trainer on 26th July, had been "controlled" or re caught by another ringer. The bird in question, a 3J or bird born this year, was controlled in Martham Pits in Norfolk by members of the East Norfolk Ringing Group, 38 days later, a movement of 210km.
This isn't the only Swallow ringed at The Avenue that's been recaught. See here and here for details.
