Nordic Jackdaw

The combination of the Christmas festivities and the weather has meant that I've not been out much recently. I've trudged across the snow to the frozen river Thames to check the largely birdless desert that is currently my Port Meadow patch but apart from that I've not really ventured out much. Because of the harsh weather I've been feeding the birds religiously and as a consequence have been getting many more visitors to the garden. The most interesting displaced bird was probably a meadow pipit actually down on the ground (as opposed to flying over which I've had before). A couple of male blackcaps and a fieldfare have also put in an appearance so there's always been something to look at. About a week ago I spotted a jackdaw that came down to my makeshift table which is a large flower pot tray nailed to the top of the trellis so as to be out of the way of the cats. What was noticeable about it was that it seemed to have a well marked pale neck collar. Having studied my Collins bird guide I knew that this could mean a Nordic jackdaw but the bird flew off before I could get any sort of shot. I tried to re-locate it and spent some time poking my head out of the velux windows at the top of the house in order to survey the local jackdaw population. After a while I spotted the bird on the chimney pots a couple of houses down. With a bit of acrobatics, I leant out of the velux with a hand-held scope and digiscope camera combination and managed to come up with a shot.

I sent the shot to Ian Lewington (our esteemed county recorder) who was intrigued but said that one had to be careful because at that angle the base of the neck area can be somewhat exaggerated and would it be possible for me to get some eye-level shots instead. I wondered just whether I was actually going to see the bird again at all let alone get some more shots but as luck would have it it's visited the garden at least once on each subsequent day and today it actually stayed put on the bird table for quite some time so that I was able to get off a good load of shots and to see the bird from various different angles. I also took some photos of a normal jackdaw which pitched up a few minutes later by way of comparison under the same lighting conditions.

This is a normal jackdaw...

normal jackdaw: note how at certain angles there can be a hint of a collar surrounding the base of the neck, caused by the light catching the end of the neck feathers.

The rest of the shots are all of the candidate bird. Note that there's no doubt about the fact that the pale area is more than just catching the light at a certain angle.






Although you can't see it from these photos I can confirm that the neck pattern is the same on the other side so that it's not just some aberrant feathers on one side but rather a consistent pattern on both sides of the neck.

If I've interpreted my Collins correctly, the jackdaw (corvus monedula) that we get normally get in the UK is c. m. spermologus. In Finland, Russia and E. Europe it's c. m. soemmerringii which has a distinct pale half collar going all the way around the back of the neck. Scandinavian birds (known as Nordic jackdaws) c. m. monedula are described as somewhat intermediate which would fit this bird as it has a distinct collar but it doesn't go all the way around the back of the neck, being confined to the sides of the neck. Ian Lewington helpfully sent me a link to some Nordic jackdaw shots which shows the wide variation within this sub-species and my bird certainly would fall within the range shown and some of the plates there show the identical side collar markings. After chatting with Ian Lewington it seems that it can certainly at least be claimed as a bird "showing the characteristics of Nordic jackdaw". A very nice garden find!

Still not doing a year list...

With the weather having not been very conducive to birding recently I was feeling a little bit cabin feverish and needed to get out. As regular readers may know, I'm not doing a county year list this year but I still keep an eye on what birds I still haven't seen in the county this year (marked in red on my spreadsheet) and when there's nothing better to do I go off and see some of them. Therefore for my trip today I thought that I'd head west into the murky depths of the county near Standlake. There were three "red birds" on offer in this area: some Bewick's swans at Shifford, a red-breasted merganser at Pit 60 and the tree sparrows at Tadpole Bridge which it would be rude of me not to drop in on whilst I was in the area.

I was just heading along the A40 when I got a text from Badger saying that there were now 8 swans at Shifford. I told him I was on the way so he waited for me. Sure enough there were 7 adults and a juvenile all grazing away with some mute swans at a reasonably close distance to the road. I took some obligatory record shots and chatted with Badger for a while before we went our separate ways and I headed off to Pit 60.


The light was abysmal this morning so these digiscoped shots were taking at ISO 800. They've not come out too badly, thanks in part to the great noise reduction capabilities of Paint Shop Pro which is the editing software that I use. I understand that Photoshop's noise filter isn't that great and people often resort to using third party software for noise.

Pit 60 is a former gravel pit (part of the Lower Windrush complex) that has been made into a nature reserve with a couple of hides. The walk down the lane was longer that I was expecting (a few bullfinches being the main birds of note) but whilst en route I met up with Mr. Pit 60 himself, Antony Collieu, who lives in the village and checks out the pit frequently. He said that it had been a very quiet year for the patch with nothing of particular note having been found there this year apart from a recent weather-displaced bittern and the merganser though unfortunately the latter had flown off a couple of days ago with a bunch of goosander. Despite my target bird having gone I thought that it would be interesting to take a quick look so we visited both the hides. All the birds were at the southern end standing on the edge of the ice around a large ice-free area and the only bird of note was a single distant red-head goosander. I thanked Antony for his kindness in showing me around and headed back to the car.

My last stop was Tadpole Bridge for the tree sparrows. In the back of the car park there are a couple of feeders installed and I positioned myself so that I could watch them from within the car. Four tree sparrows soon came down but left before I could take any photos and I spent a fruitless further quarter of an hour waiting for them to return. I decided that I had to get back but as I turned the car around low and behold there were several of the little beasties sitting in the hedge behind me quite happily. I recalled that Badger had said that exactly the same thing had happened to him when he visited so for future reference it's worth checking the hedge out first! I took a few point & shoot camera record shots for the blog though there was no light to speak of. I'd suggest partaking of a little something at the pub by way of gratitude for using their car park and for supporting the tree sparrow project. Whilst on the subject, it's worth acknowledging the amazing work that the volunteers do for the tree sparrow project in the county: this little bird has gone from strength to strength since they started and is gradually spreading further and further along the Thames. Thanks guys!

Cornwall: Winter Birding

It was time for me to head west once more down to Pendeen to check on what the builders had been up to since my last visit. The rest of my family had had more sense than to leave the warmth of the house so it was just going to be me. I put on my sad face when I discussed this with the family but secretly a part of me was thinking: "hoorah! more birding time!". This time I wasn't going to be doing any DIY but just to inspect the work and to meet up on site with the builder so it was going to be a flying visit: down on Sunday and back on Tuesday. As usual I took a look to see if there was anything of interest birding-wise to stop off at on the way down but the best I could come up with was the long-billed dowitcher at Lodmoor in Weymouth. Calling it "on the way" was stretching it I know, but technically going down via Weymouth would only actually add another 20 miles to the journey though probably add at least an hour in travelling on the minor roads.

Sunday 5th December
I had been thinking of heading off pretty early on Sunday morning but the forecast was for thick fog for much of the southern half of the country which would only slowly clear and I didn't want to arrive at Lodmoor too early only to be stuck in the car park waiting for the fog to lift. Eventually I hit on the brain wave of googling for Weymouth webcams and found one which showed that it was nice and clear on the coast already so I set off at around 9:30, arriving a couple of hours later to be greeted by bright sunshine and temperatures verging on balmy after the last few days. The dowitcher had been reported at the viewing shelter a couple of hundred yards from the car park over the last few days so I headed off in that direction. There I made enquiries only to be told that it was currently on show at the "hump" (the south-east corner of the reserve) and that the red-breasted goose was along the track that runs along the east side of the marsh, in the last pool on the right. I'd not bothered to switch on bird alerts for Dorset so the goose was news to me. I headed off in that direction and soon found the hump. There were plenty of birds to look at: dunlin, black-tailed godwits, lapwings, snipe, shelduck and teal being the main ones. The habitat looked really good and the birds seemed to be relishing it. I couldn't immediately see the dowitcher so I decided to go and check out the goose first.

The goose was on a half-frozen pool where it was swimming around and bathing, doing a rather strange somersault as it did so which I've not seen any bird do before. I took some video footage though one was viewing through reeds so the it's rather frustratingly obscured. No one there had any particularly strong thoughts on its provenance though it was apparently not the plastic bird that has been down in Devon and it was not reported again after that day.

Having "lucked in" (using the UK definition where "lucked out" means to have bad luck, whereas in the US it perversely means to have good luck!) or perhaps I should say "jammed in on" the goose, it was time to go back for the dowitcher. I strolled back to the hump and worked out that there was a blind spot behind the hump itself. I therefore repositioned myself and soon found it busy feeding away. Shortly after it flew to an easier point to view and gradually worked its way closer and closer so that in the end I had excellent views. Naturally I tried digiscoping it but discovered that a dowitchers have their bills under water almost all the time so that one has to keep one's finger held down constantly on the camera shutter hoping to capture the brief moment when it pops its head up. In this respect they're even worse than godwits which also have this characteristic. Anyway I managed a few acceptable shots as well as some video footage.


The few shots that actually had it's bill out of the water!




Some video footage of the dowitcher feeding. My apologies for the loud conversation going on in the background - it wasn't anything to do with me.


Not wanting to arrive too late in Cornwall and concerned at how long the cross country section from Weymouth back to the motorway might take, I didn't hang around too long before setting off again. As it turned out the rest of the journey was fine and I arrived in Cornwall just as it was getting dark. Having consulted the tide timetable before coming down I knew that high tide was at dusk today and would be even later tomorrow. As I was keen to see the purple sandpipers on the rocks by Jubilee Pool I knew that today was going to be my best chance so I headed straight over there. They weren't there when I peered over so I had a little wander around the harbour peering down at the harbour walls for possible roosting spots. All I could find however was a few turnstones and rock pipits so I headed back to the usual spot where amazingly the birds had turned up and were all tucked up asleep. There were about 15 sandpipers and a similar number of turnstones all standing on the edges of the harbour wall. I took some photos though in the half light they are of poor quality.

After that I headed off to the supermarket to buy provisions for the duration of the stay then it was off to the cottage to store the food in the fridge & to have a meal. The cottage was absolutely freezing as they were still installing the central heating so I did little more than nuke up a microwave curry, gulp it down and head off to the B&B in Pendeen (The Old Chapel) where I was staying. This had the most amazingly hot hot water for a reviving bath and a pub conveniently located on the opposite side of the road. After such a long day I slept well that night.

Monday 6th December
I had a meeting on site at 9:30 with the builder so I thought that I would nip down to the Lighthouse for a spot of sea watching before hand. It was a very bright sunny day and with the sun directly behind me the birds were all nicely lit and showed up well even at 1/2 and 3/4 distance. I had wondered whether there would be much about but there was always something going by even though it was just common stuff. Eight or so manxies went through and there were plenty of auks zipping past. I was looking out for little auks and did spot one which looked smaller. It even caught up with a line of slower auks so that I reasonable size comparison was possible but it was not small enough for a little and was probably therefore a puffin.

Back at the cottage there was much to discuss: some radiators had been installed in the wrong place and they were that afternoon about to install the oil storage tank on a piece of land that we didn't even own - thank heavens I'd actually come down when I had! Anyway all this took up the rest of the morning so it wasn't until early afternoon that I found myself free again for some birding.

There was not much of particular note about in the area at present so it was a case of doing the rounds of the local spots to see what I could find. As part of my local birding education I was keen to visit some spots that I'd not really visited before so first port of call was Kenidjack Valley, in particular the sewage works, where I reasoned any remaining small warblers were more likely to be hanging out. On the way down the valley I came across a tit feeding flock and I scanned around for some more exotic hangers on though all I could turn up was a goldcrest. I walked down to the hamlet near the ruined chimney before heading back up again.

On the way back there seemed to be more bird activity by the settling tank and I found a grey wagtail, two pied wagtails and a single phyllosc. which immediately had me thinking tristis. It had a very pale white underside (√° la greenish warbler), black legs, green tinted wings but paler brown upper body and head. It had a very faint single buff (not white) wingbar which I suspect only showed up because of the very bright light. Unfortunately it never called but it looked just like the comparison image of the tristis next to the greenish warbler in my Collins!

Next on to Sandy Cove at Newlyn where a slavonian grebe had been reported regularly each day. I managed to find a great northern diver but could not find the grebe though a local later told me that he'd not seen it in three visits down there which made me feel better about not finding it! A quick stop off at Jubilee Pool though it was, as I suspected, too early for any roosting sandpipers. Next on to Long Rock beach car park to scan the bay. There was another great northern diver quite close in but nothing else of note so I moved further along to Marazion beach where fortunately there were plenty of parking spaces at this time of year. There I passed a very pleasant three quarters of an hour watching the waders who were very close now that it was approaching high tide. The sun was shining a wonderful golden yellow (it was what photographers call "the golden hour") and the birds were very approachable. There was a good number (a couple of dozen) each of dunlin and sanderling, a single redshank and a single knot. with the odd ringed plover dotted along the beach. I met a local birder and we scanned the bay together for a while and he managed to pick up a distant red-throated diver over towards St. Michael's Mount. He also spotted a black redstart further along the beach hopping on and off the wooden posts.

Once it started getting dark I headed back to Long Rock Industrial Estate to pick up some bathroom brochures and to chat to the people there about what we were looking for for the cottage. It was not quite fully dark when I finished so I nipped back to Long Rock pool where there were a couple of birders waiting to see whether any bitterns would come in to roost there (apparently there'd been four there the previous evening). It turned out I'd missed one by twenty minutes and no more came in. Whilst I was there I got chatting to a local birder who soon asked if I was Adam Hartley! Amazed, I said that I knew that Cornwall was a small community but that was still quite impressive. It turned out that he read the Pendeen Birding blog (my Cornwall-only version of this blog) and had worked it out from my saying that I was renovating a cottage at Pendeen. We had a good chat and he told me about a red-necked grebe that was currently at Carbis Bay and how to get there. He also asked whether I was thinking of compiling a Cornwall county list and I confessed that it had crossed my mind. I'd found myself thinking of county ticks when spotting even common stuff such as mistle thrushes etc. He told me that some common birds such as treecreeper and nuthatch are hard to find at this end of the county so I would have to go further up to get those. Eventually it got too dark for any more bitterns to come in so I headed back to the B&B for a cup of tea, followed by a pub meal and another hot bath.

Tuesday 7th December
I had another meeting with the builder this morning but it was earlier than the previous day so there wasn't time for a sea watch before hand. The meeting took longer than anticipated so it wasn't until late morning that I was free from my duties. I wanted to do a bit more birding before heading back home and was thinking of heading over to the Hayle area to see what was about. On the way I popped into Drift reservoir to see if the two geese (a Greenland white-front and a genuine wild neck-ringed greylag were about) but they appeared to have gone and there was little of note there.

Down at Hayle I first visited the Leylant Saltings platform. There was plenty of excellent light though as it was low tide the birds were widely scattered and somewhat distant. There was nothing of particular note to be seen. There was supposed to be a curlew sandpiper about but the dunlin flock (where it was probably hiding) was right on the other side of the mud flats. I did a some brief digscoping of a nearby grey plover.

Next on to Carbis Bay which I'd not previously been to but which turned out to be a great spot. From a vantage point in front of the hotel one could overlook the bay and easily see a wide area. There seemed to be some sort of feeding frenzy going on with a large concentration of gulls in two spots as well as quite a few seals and I guessed there must have been a couple of fish shoals there. Over on the left-hand side close to the rocks I soon spotted the red-necked grebe and in the same general area was a female-type eider which (according to the chap I was chatting with yesterday) is not so common in Cornwall. On the diver front there were three great northerns and a single distant red-throated. There was also a flock of gadwall, a single red-head goosander near the rocks and another flock of three red-headed sawbills which I didn't have time to check before they moved on. There were loads of cormorants and shags and a single razorbill. A couple of birders turned up, armed not with a scope but what looked like a giant pair of war-time binoculars mounted on a tripod. We soon got talking so I pointed out what I'd found. After a while it was time to move on.

There was one final spot that I wanted to check in on, mainly because I'd not actually been there before and I wanted to suss out parking etc. so that I knew where to go should a rarity turn up there and that was Carnsew Basin. I found somewhere local to park and had a little wander along the southern end. There was not much to see apart from a reasonable dunlin flock, a few bar-tailed godwits, a single oystercatcher and a few grey plover. On the water itself there were a few distant little grebes. I did some more brief digiscoping as the light was so good and then decided that it was getting late and I should be heading back

The journey back was uneventful, though after a while I hit freezing fog and rather pretty hoarfrost on the trees which lasted up until the M4. Whilst travelling back I was listening to the traffic reports and being profoundly grateful that I wasn't up in Scotland! It had been a most enjoyable return to my favourite part of the country and a great opportunity to experience winter birding there.

The Birding Gods Smiled Down...

Saturday morning is when I do the weekly supermarket shop. This particular chore has fallen to me for several years now and I actually don't find it too onerous. At the same time it also accrues vital Brownie Points and well all know what Brownie Points make - that's right, birding! Anyway, I was just heading off to the supermarket when I got a text from Badger saying that he'd just found a glaucous gull at Appleford Pit. To be honest, my heart sank on the news.: not only was I tied up with shopping chores for the next hour and a half but Appleford can be a very hard place to track down individual gulls as there are so many places that they can go. There is a very nice pit (the Spit Pit) from which birds can easily be viewed but if the target bird isn't there then it's either a distant blob in some field somewhere around or it's on the tip itself or one of the satellite pits. These last two locations are inaccessible to your average birder though our esteemed county recorder Ian Lewington (whose patch Appleford is) has special access rights. When the Azorean yellow-legged gull turned up at Appleford last year it took a number of visits before I finally managed to see it. Knowing all this I wasn't feeling overly optimistic about my chances. Indeed I didn't even hurry over my shopping and positively dawdled on my way home. It was only as I pulled in the drive and I got a text from Badger saying that the bird was still there that I started to contemplate actually going for it. Having even unpacked the shopping (which is usually my VLW's job) I decided to cash in the Brownie Points and told my VLW that I was heading off to a rubbish pit to look for a single gull amongst thousands. She just shook her head pityingly and said nothing.

It was some half an hour later that I pulled up besides three other cars next to the Spit Pit. When birding the Pit its generally a good idea to remain in the car as you can put up the birds if you're not careful. Also given the freezing temperatures staying in the car was a sound move! I therefore manoeuvred the car next to Badger's and through wound-down windows I discovered that the bird was still there standing on one of the banks. I soon found it, a whacking great white thing which really stood out from the throng. I hurriedly set about trying to get my tripod positioned for some digiscoping which is not so easy within the confines of the car. However whilst I was still struggling with this task the bird took off, did one circuit of the pit and then flew away. I realised that I'd managed to arrive with just minutes to spare and I'd been very lucky to catch up with it. The Birding Gods were indeed smiling down on me today!

As I'd not been able to photograph the gull itself I thought that I would take a background shot of the Spit Pit, with the tip behind it and Didcot power station at the back. Most scenic!


Fortunately Ian Lewington took these excellent images of the bird, a second winter, earlier in the day which he's kindly allowed me to reproduce here (c) Ian Lewington

Now you all may be wondering about the big fuss over what is not such a rare bird but during the three years that I've been birding in the county there have not been any twitchable glaucous gulls so this was in fact a county tick for me. Pathetic I know but I was most pleased to have laid this bogey bird to rest.

Waxwing!

It has seemed as though every part of the country apart from Oxfordshire has been swamped by waxwings this season. Within the county there had been a few tantalising fly-over glimpses and recently a pair had spent the morning in the farthest reaches of the county before being flushed by a sparrowhawk. So when I got a text from Nic Hallam saying that there was a waxwing in Botley it was too good to resist and despite the cold weather I set off and soon managed to connect. The bird was feeding on berries next to the church hall in Botley, Oxford though whilst I was there it spent most of its time at the top of a tall tree on the opposite side of the road, only making brief sorties across to the berries, gulping down a few before returning to its lofty vantage point. I took a few digiscoped shots whilst it was in the tall tree and eventually worked out that to get any shots whilst it was on a berry sortie I would have to be very quick so in the end I opted for shooting some video during the berry raid. Let's hope that it stays and even that it's joined by some friends, they're such lovely birds!


Having a bad hair day!
