ID blooper- my white- throated-non-barred-eastern sub- Ruppell's warbler!

I hold my hand up and readily admit I made a howler of an ID blooper near the Butt of Lewis last Friday! I don't feel the need to make excuses- I have never considered myself to be anything other than an average birder with (obviously) limited experience of many tricky species. I still learn something new whenever I'm in the field. However, the way things transpired with subsequent suggestions of mega and rare bird species, coupled with a couple of negative/petty comments suggests that it may be beneficial to put the record straight.....

Having been out all morning looking for migrants at the Butt of Lewis in challenging conditions (Near gale- NNW Beaufort F7/intermittent, persistent rain and very poor light), I worked my way down to the dense cover of the garden at the rear of what used to be the Eoropie tea room. At about 30 metres from the garden I had a split second flight view of a 'sylvia sp.' that I initially thought could be a whitethroat. I saw the bird alight briefly and dive into dense foliage. Later, I managed a few dreadful photos of a pale grey, skulking bird in the swaying and buffeted vegetation. After 20 minutes or so, the bird again showed fleetingly and appeared sluggish and heavy. It was a pale bird against a dark background and in the wet and gloom I fell into the trap of thinking the bird was bigger than it obviously was. Soaking wet and cold and with rain on my 'foggy' glasses, bins and camera I trudged back to my accommodation to dry out. I downloaded some reasonable shots of ruff and black-tailed godwits taken during a 'dry' interlude and sent off a few shots of those to some birder friends and without really thinking I also attached my best 'whitethroat' shot. Later, after a shower and much coffee, I pondered the rest of the photos and realised with some consternation that the bird was not a whitethroat, but that it reminded me of a couple of barred warblers I had seen previously on Shetland during similar autumnal conditions. I sent out photos to some very capable and respected birding friends asking if this skulking bird could be a barred warbler. The photos were not great and they concluded the following morning that it was a 'probable' barred warbler although I must stress that it was my call. Later I met up with a local birder who asked if the 'barred warbler' sighting/photos could be put out to a 'local' email group to which I readily agreed. At the time I was not aware that the email distribution included RBA admin. and Birdline Scotland! I decided to go for a sea watch at the Butt for an hour, enjoyed a few sooty shearwaters, then once again returned to the tearoom garden. As I approached the garden the local birder pulled over and said 'Andy- I have been trying to phone you'! I have good news and bad news....... your bird is not a Barred warbler- it's a probable Ruppell's warbler- yikes! To be totally honest I had to look in a field guide to check exactly what a Ruppell's warbler looked like! I felt excited but also rather sheepish in consideration of the implications of my ID error and felt a strong desire to put my head down a rabbit hole! The rest is history. The weather improved, the bird was seen by two other observers and much better photos. were obtained. With further, better quality, photographic evidence available to the wider birding community, the bird was subsequently re-identified as a probable eastern subalpine warbler. Having now seen the other observers' superior images, I admit to being rather horrified at how different the bird looks from when I first saw it in the field when much of the plumage detail, leg colour and bill size were far from obvious. 

I received two, petty messages, from unknown 'birders' that were childishly rude and very critical of my error- these were immediately consigned to the bin! I also received a number of texts, phone calls  and emails from a number of very good birders from the Highlands, Hebrides, Shetland and Cornwall who have all been very supportive and have pointed out that many birders make mistakes when in the field and that most criticism comes from those armchair birders that rarely get out in the field in poor conditions. The digital age has become a welcome tool in sorting out tricky birds but gives little or no reference to field conditions and in some cases it has become far too easy to look at others'  photographs post sighting, from the comfort of warm, dry rooms with field guides to hand. I made a mistake yes, but it has been a useful learning curve and certainly won't stop me from getting out in the field and continue trying to improve my birding abilities. Hopefully the next time I find a rare bird I'll be able to ID it accurately. I would like to thank the birders who have been supportive - you all know who you are! Many thanks also to those gifted birders (sorry- don't know your details) that contributed to the debate with suggestions of Ruppell's and ultimately eastern subalpine warblers - hopefully a little more has been learned about the identification of these birds by the wider birding community and that can only be a positive. When all is said and done the bird is still a great record for the Outer Hebrides- now I have to sort out what the description criteria are?....

Gairloch pelagic- the Minch.

A boat trip in the Minch is always fun and with recent reports of Orcas and Sabines' gulls to whet the appetite I jumped at the chance of a place on the Hebridean whale cruise 'Orca 1'- a large fast RIB designed to cover big distances at speed. The weather and sea conditions were ideal- flat calm with good visibility although the light was very flat due to the hazy conditions. Within 15 minutes of setting sail we were surrounded by a pod of circa 500 common dolphins that obligingly played around the vessel providing outstanding views. A short while later we watched a minke whale- the first of 5 encountered during our trip. Harbour porpoises seemed to be every where. Birds were not as abundant as I had hoped but we recorded sooty shearwaters, manx shearwaters, an arctic skua, a possible long-tailed skua and 3 pomarine skuas. Great skuas were abundant as were over 50 storm petrels. Unfortunately no orcas or Sabs. were seen but we also saw a pair of bonus white-tailed eagles on the return leg and a flock of 28 black-throated divers

Shear delight

After a few days of fog and light, variable winds, the forecast of a reasonable blow with a significant westerly element raised my pulse rate and guaranteed that I was on watch early the following morning. I was not disappointed, as two great shearwaters flew 100 metres or so off the port bow as I gathered my waterproofs, hat, notebook and binoculars from the bridge! From then on and over the last three days I have enjoyed three figure counts of great shearwaters, intermingled with scores of Cory's! Some birders would say that when you have seen one large shear you have seen them all, but I disagree, find them totally captivating and have no problem watching them shear and glide over the swell and waves for hours on end. Surprisingly, and contrary to the large numbers of sooty shearwaters reported from Irish sea-watching sites, I have only seen one in the last 3 days- maybe they hug the Irish coast more as they drift SE? I also had the bonus of seeing flocks of Sabines' gulls- a group of 3 and a group of five. Unfortunately being on a 92 metre vessel, with a GRT of over 9000 tonnes means that many birds are rather ship-shy, occasionally however, a large shear made a relatively close pass, allowing me to try for a couple of shots. Good numbers of Arctic and 'comic' terns have also been seen flying south and an additional grey phalarope and a turnstone have been the only other obvious passage birds. I suppose we should see some significant skua passage before too long, but with the exception of a solo, spoon-laden pom and a few locally foraging bonxies they have yet to make an appearance. Happy days!

great shearwater- close pass at last!

The Porcupine Seabight

The Porcupine Seabight is an interesting oceanographic feature located a hundred or so nautical miles  WSW off the southern coast of Ireland. It is a large depression where the water rapidly deepens and leads out to the abyssal depths of the North Atlantic. The strong ocean currents form nice areas of nutrient-rich upwelling so there is often an abundance of marine life- plankton, shoals of pelagic fish including albacore and yellow-fin tuna, cetaceans and seabirds- at least that is what it said in the tourist brochure! In all honesty there have been good numbers of fin whales- sometimes 5 or 6 in a day, the fishing fleets of Ireland and Spain are actively fishing for tuna, but seabirds have been rather scarce. Admittedly I see gannets and fulmars every day but numbers are low. A few lesser black-backed gulls have followed the survey vessel on occasion and I have had good days where I have seen four species of shearwater- Great, Corys, Sooty and Manx- but again numbers have been disappointing. I have also see a few bonxies, 2 Sabines gulls- both magnificent adults in summer plumage a few storm petrels and 1 wilson's petrel- I can't complain but I hope that numbers increase over the coming weeks! Unfortunately I have struggled with poor light and distant birds so taking photographs has been challenging, although this morning a great shearwater came within 40 metres of the bow, allowing me to rattle off a few snaps. Hopefully the sunshine and a nice Fea's or Bulwer's petrel are not too far away!

Butt of Lewis-sea watching!

Just back from a great 4 day birding break at the Butt of Lewis- the most northerly point in the outer hebrides and one of the more remote points in NW europe! Although rather early for a sea watching stint I had to visit now as I'm heading back to work next week and so will miss the more traditional sea passage time- in the UK at least!

Since I was a child and saw my first light house at Lands end Cornwall, I have always had a fascination  for the way they dominate land and sea scapes. I always fancied working as a light house keeper in my youth.

Despite being early in the season for sea- watching, there was enough to keep me occupied for four days:- in addition to the usual suspects of fulmar, gannet, kittiwake, puffin, guillemot, razorbill, common, herring, gbb and a few black-headed gulls,  there was a light passage of sooty and manx shearwater and sporadic sightings of great skua, arctic skua, arctic tern and red-throated divers. Around loch Stiapabhat I also recorded hen harrier, peregrine, golden plover and lapwing. On occasion it was great to see whimbrel and redshank coming in off the sea.

Other marine sightings of interest included a basking shark and an ocean sunfish. On the cetacean front I also recorded minke whale, Risso's and bottle-nosed dolphins, harbour porpoise and two orca! Not bad for a shore-based sea watch stint!
