Cornwall - 12th-16th January

Sarah, Tobias and I had a long weekend in Cornwall at our cottage at Trowan a couple of miles west of St. Ives. The cottage is located on a spectacular stretch of coastline which is designated an AONB, it is wild, rugged and unspoilt. We were primarily down to meet builders as the cottage needs to be redecorated but at the same time we are going to reconfigure walls to change room dimensions. We also wanted to relax in front of the fire and do little after a very frantic time at Christmas and period at work. However, on Saturday 14th I met up with my good friend Nigel Wheatley and we spent the morning looking for some of the long staying Cornish rare's. I picked Nigel up from St. Just at 07:45 and we headed straight for Mousehole. The target here was an 'Eastern' Black Redstart that has been present since 18th December 2016 and is the phoenicuroides race of Black Redstart that I have not seen in the UK previously. I have however seen this race elsewhere most recently in India on 11th February 2016, see here. We arrived at the car park in half light but Nigel almost immediately picked up the bird on the path running alongside the beach. Over the next hour or so we enjoyed great views of this stunning little bird as it fed amongst the rocks on the beach. Also here were Grey Wagtail, Mediterranean Gull and despite scanning through the gull flock we failed to find the recently reported Kumlien's Gull.

There are around half a dozen accepted British records of 'Eastern' Black Redstart up to 2015. However, in 2016 there were an amazing nine records (approximately), this influx no doubt as a result of the near constant flow of easterlies during the autumn period. There are currently two wintering Eastern Black Redstart in the UK, the Mousehole bird and another at Skinningrove, Cleveland. This latter bird having been present since 27th October 2016. While there are some that advocate Eastern Black Redstart as a full species the recently published Volume 2 of the Illustrated Checklist of the Birds of the World (Lynx Editions) treat this as a race of Black Redstart and although typical males are distinctive integrates between the various races occur. Maintaining one species with five races would seem the most sensible approach - unless one simply wants to bump up ones list!

We then went on to Jubilee Pool to look for the Pacific Diver. We spent almost two hours scanning out to sea seeing four Velvet Scoter, 15 Common Scoter, seven Great Northern Diver and 11 Purple Sandpiper. A brief view of a Black-throated Diver was almost certainly the Pacific Diver but unfortunately the bird was lost after it dived and despite there being five birders present we could not relocate this bird. However, from the view I had there was no flank patch so it would appear to have been a good candidate for the Pacific Diver - one that got away unfortunately.

We then went onto Perranuthnoe for the Hudsonian Whimbrel. After parking at the car park we walked the coast path westwards and on arrival at Boat Cove we found the bird fairly quickly feeding among the rocks. We repositioned ourself to the west side of the cove as the light was better but unfortunately the bird flew and disappeared into the distance - still, my fifth visit and I had at last seen the bird fairly well.  Also here were five Black-throated Diver offshore, three giving cracking views, a single Great Northern Diver and a Mediterranean Gull. The Hudsonian Whimbrel was first found on 15th October 2015 on Tresco, Isles of Scilly before it moved to Marazion on 30th October, it has been present here now since then. There are 12 records of this race in Great Britain since 1975 with the Cornish bird being by far the longest staying bird although there is a general tendency for long staying birds, the next longest staying bird being the Pagham Harbour bird which was present from 9th June to 27th July 2015 2015, a total of 49 days. Again, Volume 1 of the Illustrated Checklist of the Birds of the World (Lynx Editions) treat this as a subspecies of Whimbrel but identify it as a potential split, American Whimbrel.

All too soon, our morning was over and it was time to say goodbye to Nigel and head home. In the afternoon Sarah, Tobias and I walked the beach at Marazion and I spent some time scanning again for the Pacific Diver but with no luck but the light was poor. The highlights were two Velvet Scoter and a Common Eider.

On the morning of the 15th I managed a short visit to the Hayle Estuary where a Green-winged Teal has been present since 10th November hanging out with the Eurasian Teal from the B3301 causeway. On arrival I located the bird fairly quickly but during my 45 minutes there it slept for much of the time. t was not until I returned home that I noticed the bird was ringed, unfortunately, the bird was too distant to read the combination but it includes the numbers 08 and an address. Again, Volume 1 of the Illustrated Checklist of the Birds of the World (Lynx Editions) treat this as a subspecies of Eurasian Teal but identify it as a potential split. Also here was a Spoonbill, four Mediterranean Gull, 12 Bar-tailed Godwit 45 Wigeon, large numbers of Lesser Black-backed Gull and a possible 1st winter Caspian Gull which  looked pretty good but  took my eye off the bird to check some characters on my Collins app and the bird had flown by the time I looked back.

Finally, on the 16th I managed to persuade Sarah to drop into Marazion for a short while to scan for the Pacific Diver. It was calm and the bird had been reported off the beach for the last couple of days. I picked up eight Great-northern Diver, five Velvet Scoter and finally, very distantly, was the Pacific Diver - even at this great distance the lack of the flank patch and the dark chin-strap could be seen. I rattled off a couple of shots, not even able to see the bird in the view finder and I ended up with one shite image of the bird.

This is the Pacific Diver or 'Pacific Thing' as Nigel called it - you have to trust me on this!! I think the throat strap is just discernible but it was far more visible in the field
