Ringing recoveries


A couple more recoveries have been sent through recently of birds ringed in the county...

Ring number Z604156 was placed on a juvenile Reed Warbler at Stortons Gravel Pits on 5th July 2015. It is very likely that Stortons was the location where this youngster was hatched. On 3rd July 2016 this bird was caught at Stanford Reservoir and gave the indication that it was breeding there. The distance between the two sites is about 24km but of course this bird would have wintered in Africa between these dates.

A juvenile Tree Sparrow was caught and ringed at Pitsford Reservoir on 6th October 2012 and on 1st September 2016 it was found recently dead at Walgrave. Although this bird may not have travelled far, four years is a good age for a Tree Sparrow (1426 days between ringed date and being found dead). Not all the Tree Sparrows feeding locally in the county during the winter originate from Northamptonshire. There are now at least three instances of birds initially ringed in East Yorkshire in the autumn being subsequently controlled here in the East Midlands, suggesting that some birds in north England  (predominately juveniles?) move south and winter in this region.

This afternoon (Saturday) and an adult Yellow-legged Gull was with Lesser Black-backs in fields in the Brampton Valley below Hanging Houghton and a Kingfisher was on the Brampton Brook.

An evening visit to the Sailing Club at Pitsford Reservoir failed to locate anything much different - the Ruddy Shelduck was there as well as at least two Yellow-legged Gulls.
