...and in British Birds Jan 2019

In July 2008 a Storm Petrel was caught bearing a Portuguese ring. One of our group, taking photographs and with time to look, noticed what he thought was a deeper 'thicker' bill than was usual for Hydrobates pelagicus pelagicus (nominate race). It was considered it might be a H.p. melitensis - the Mediterranean form of Storm Petrel. With due diligence and reference to others more knowledgeable in the field, plus the fact that this bird had been ringed by Rob Thomas of Cardiff University on 7 July 2007 at Ponta de Almadena, and had had samples taken for DNA, subsequent analysis was able to show it was pelagicus.
Adding melitensis to the British list was not to be, bad luck Stephen, but what this article did demonstrate was the difficulty in identification that remains for this species - even the deepest-billed birds may not (necessarily) be melitensis.

GB recoveries (1)

All of these individuals were originally caught and ringed by us and then recaptured by someone else.

The first two were caught by us on Nan Ron in July 2017 and were both recaught the same day in 2018 on Birsay, Orkney by the Orkney RG, 361 miles away.

2018 catch-up

I don't have final figures yet for 2018 as I'm still waiting to find out whether some of the birds we caught were either retraps or controls but we will be looking at about 740 new birds ringed.
I do however have some recovery data on those records submitted to date.
Firstly, this post, three late reported Norwegian recoveries.
