Since its inception the group has ringed a total of 23,608 Sand Martins mainly at the colonies in the sandy banks of the River Lune. To date we have had 48 recoveries on passage through France mainly caught by French ringers, all were of birds caught as adults or juveniles. Of the 48 reported 31 were in July, mainly young birds but because they were caught after fledging we had no way of knowing
exactly how long they took to reach France. However this year Dave ringed 56 nestlings at an artificial site and one has just been reported in Northern France just 33 days after ringing. It probably took 5-6 days before it fledged so it had started its migration south about 25-27 days after fledging when it was only about 45 days old. Amazing! It had traveled 493 kms SE when caught.
