Autumn migrants going the wrong way and more Welsh Stormies

We've just received a whole batch of reports back from the BTO detailing some movements of birds to and from the group area. There were rather a lot of local movements, but here are some of the highlights.
Our great run of Storm Petrel movements continues (see the first few here), with yet more movements to and from Wales. This time we received details of four birds ringed at The Lizard that were recaught in Pembrokeshire, on Skokholm Island and at Wooltack Point. Two of these were birds ringed in 2012 and 2013, but the others were quite quick same-year movements, at 38 days, 26 days and 20 days. In fact, all of these last three were ringed on the same date (30th June), the same date we also caught a Portuguese-ringed bird.

The Portuguese-ringed Stormie caught back in June
We then just had one Storm Petrel movement he other way, from Skokholm to The Lizard (194km), but in managed this in just one day! It was ringed at 00:40 on 24th July and recaught down at The Lizard at 00:30 on 25th July.
Two rather more unusual reports came from Nanjizal, with migrants moving north in the late summer/autumn. A Sedge Warbler ringed on 21st August was recaught 250km away in Dorset seven days later (so moving northeast) and even more bizarrely a juvenile Sand Martin ringed on 10th July was recaught nearly 500km away in West Yorkshire six days later! This again is a very quick northeasterly movement and seems most odd...
