Mark Cutts and Verity Hill, our stalwart owl-catchers, had a huge surprise yesterday evening when one of the Barn Owls they trapped in the Crown Estate Field at the Bill turned out to be a control, already ringed - and in fact also colour-ringed - elsewhere:
We received the ringing details today and it turns out that this bird was ringed by Tony John as a nestling 49 kms away at Chardstock, east Devon, on 7th June this year:
BTO data (from more more than 4500 chicks ringed in the UK) tells us that the median juvenile dispersal distance up to 12 months after ringing is only 6.7 kms, so a 49 km movement is very unusual indeed. A fascinating recovery and a great result from Mark and Verity's hard work © Mark Cutts
Also received today from Martin Collinson at the University of Aberdeen were the results from the lab work on feather samples of our two Lesser Whitethroats on 28th and 30th September;
Despite looking really quite different - we suspect mainly because the first bird was a youngster and the second was an adult (...although we're not sure how that explains away the noticeable wing-formula differences) - both these birds were confirmed to be blythi Siberian Lesser Whitethroats. As usual, many thanks indeed to Martin and his team.
