Two recent examples as to why Wales exporting plastic to Africa may not be the terrible act it sounds!
A couple of emails today showed the huge value to be gained from adding just a very small amount of plastic to migratory birds caught for ringing. The first, from Marcelo Cabrera, contained details (and a couple of confirmatory photos) of a juvenile Dunlin ringed at Ynyslas on 17th August 2019 and found on 2nd and 3rd of November on the North coast of Fuerteventura, Canary Islands (OK, so its Spain officially but its Africa geographically). As far as I can see this is perhaps only the 2nd recorded movement of a BTO-ringed Dunlin to the Canary Islands. We have also recently received sightings in Morocco of two other Dunlin ringed at Ynyslas this autumn.
Then, this evening, I had an email from Theuns Kruger who had just photographed Sandwich Tern Red KAL for the third successive winter at The Strand, Western Cape, South Africa. This bird was ringed at Ynyslas as a juvenile, on passage, in August 2013 and has been a regular at Dawlish warren in Devon but we are still yet to discover where it is breeding.
