Another Aquatic-less day, but perhaps an Estonian Arctic Tern instead?

With the wind hinting at turning to the east, we headed to Marazion this morning in the hope of a late Aquatic Warbler. But sadly still no luck, although 32 birds caught wasn't too bad considering how quiet the reedbed seemed. These were mostly Reed Warblers, though one of the driest net rides did catch this rather smart female Kingfisher (female by virtue of being greeny-blue instead of bluey-green) and almost caught a passing Common Sandpiper. Overnight the wind is proper easterly though, so maybe tomorrow will be the day...

A bit of extra interest for the morning came with the delivery, via RSPB, of a GPS data logger that was reported on an injured tern at Sennen Cove on Saturday. Unfortunately the bird died but the second finder only removed the data logger and not the ring, so we're still a bit in the dark as to what the bird was and where it was from! Rumour has it though that an Estonian-ringed Arctic Tern caught in Grampian recently also had a similar logger, so here's hoping...

We won't find out for a while though as the logger has to go back to the manufacturer (in Poland) to be downloaded to ID the bird. For info, the aerials allow the GPS data to be downloaded remotely to a radio base-station once the bird is back on its breeding grounds. So for those with 1107 € to spend, check out the technical specs here.

Thanks to Tony Mills for the Kingfisher photo and Terry George (Sennen Cove Birdwatching), Kester Wilson and Dave Flumm for eventually getting the logger to us.
