Med Gulls are back in town!

The last week or two has seen Med Gull numbers soar with lots of the regulars starting to show up. A scan through a flock of Med Gull will always reveal several colour rings which allows individuals to be indentified. Radipole is a great place to read rings as you can just sit in your car, scan the car park and read away. The only downside is the occasion pratt who decides to walk straight through the flock...

It was nice to see this fella back yesterday. I saw this gull as a juv when I started working at Radipole Lake and I’ve caught up with it every year since.

Plenty of others around but for some reason a lot of birds were starring at the car park?!

See

Wierd...

It goes without saying that all the rings are reported into their respective owners.

Gulls are pretty much the main attraction at Radipole at the moment except for this drake Garganey which Dave Chown found on Monday. It was still about yesterday afternoon when I eventually decided to trawl through the Teal. It doesn’t come very close and when I did it soon few off again!

I'm sure this one's right?!

Depending who you speak too, ‘Street Cred’ apparently means a lot to a birder so I’d better try to redeem myself and put on a photo of an actual Yellow-legged Gull which was a feeble reward for a days worth of gull watching. I would actually describe this bird as stunning!

It’s a cracker isn’t it! Found this one on my first scan of the morning which lead to think that it might not be the first of the day but it was. Given that I’ve not got a picture of another Yellow-legged Gull I’d better post another of the same bird. This time flaunting it’s wing pattern and sexy arm pit. Gotta love those underwing coverts!

Just so this blog doesn’t get samey, here’s a shot of a different gull species. It still has yellowish legs though...

After all that...

So after all that deliberation on last nights gull I got it wrong. I’d really thought several times about a hybrid and even mentioned it last night in the comments section when replying to another comment but for someone reason I got lumbered with the Yellow-legged Gull theory and I couldn’t really shift it! A case of trying to convince myself I suspect. It’s actually very rare that I look at the gull so closely and I guess the sheer amount of deliberation should have told me that this probably wasn’t a Yellow-legged Gull. Especially when comparing it to the other bird I featured. It really would have been more obvious if that was the case.

So many thanks to Brett Spencer who put me out my misery and told me it’s probably a Herring x Lesser black-backed Gull hybrid.

So basically scrap all that rubbish I waffled on about yesterday but all good experience and I’ve got to admit that I rather enjoy ploughing through gull photo’s deliberating ID’s. Nerdy as it is...

This is probably a really good time to mention a gull watching event at Radipole next year! Yep, I’ve persuaded the RSPB to let me do a Gull morning. As the above suggests, it won’t be anything in depth and detailed but  should be an enlightening look at gulls and what they get up to. It will be on Thursday 6^th February starting at 10am at the Radipole visitor centre. I promise it won’t be boring!!

Here's one last shot of the beast!

A fun evening in... sorry it's about Gulls!

This gull has been giving me a little bit of a headache this evening. Took the pictures last week and haven’t really looked at them since. Thought the bird was initially a Yellow-legged Gull, the darker mantle, slight yellow tinge to the legs but something was telling me it wasn’t quite right or at least there were a few small issues with some of the birds features. If your interested in Gulls read on but if your not then give up now and go watch TV or something.

Firstly, just look at the age of this bird. When I saw it in flight I put it down as a 3^rd winter bird due to the dark primary coverts and the head streaking and dark patch on the bill. However, a few things didn’t add up. I realised it should have more black in the wing if it was a 3^rd winter plus it’s got a pure white tail. So am I’m dealing with a 4^th winter bird?? If this is the case I’m now in uncharted territory, that’s not an age I’ve looked at the before. Things that strike me if this is a 4^th winter is that it should probably have a whiter head. Even a 3^rd winter has a fairly white head in my experience. Also, the legs are very washed out though this is a variable feature anyway but on average should be a lot yellower at this age.  Yellow-legged Gulls are often more advanced in their plumage and moult when compared to Herring Gulls. This poses the question ‘is this just an advanced 3^rd winter bird?

Assuming that then, take a look at this wing shot.

But compare is to this 3rd winter bird taken a few years ago around this time of year. Quite different!

 Had no doubt what so ever when I saw this bird first! Worth comparing that last shot with the first photo of the bird in question.

This evening is the first time I’ve gone through these photo’s so I’m typing this as I’m going through the details. This photo left me rather confused. There should be a small mirror (a white blob) on P10. Can’t see one there plus P5 is unmarked. Surely not a good thing for a Yellow-legged Gull. Then of course I realised the possibility that P10 could be hidden and this photo reveals all!

Top bird by the way and for comparison, the bird on the rail is a 3rd winter Herring Gull.

Small mirror on P10 and now P5 is strongly marked. Both things fit in with Yellow-legged Gull I think. Interestingly this feather still seems to be growing which has now put a little doubt in mind as to the species. Having already said that Yellow-legged Gull moults earlier than Herring Gull (and other species obviously) this strikes me a being late. I use the moult thing often with 1st years but perhaps with other ages it's not such a good thing to dwell on? There are a few adult and near adult Herring Gulls about just finishing off their moult at the moment but I think most have now finished. Not sure how relevant all that is but interesting none the less.

One of the biggest worries with this bird was its shape, structure and size. It wasn’t a particularly large bird, wasn’t  long legged, its bill didn’t seem particularly impressive and it didn’t really look long wings. The last feature I’ve obviously explained as P10 is still growing. This next shot shows it next to an adult Herring Gull. Structure can be slightly different between sexes, so going by my experience again, this is probably a female as they are smaller than males. 

 I suppose actually its fairly chunky, large headed and the bill I guess is fairly thick set. I was initially looking at the first picture rather than one comparing it to a Herring Gull. Structure can be slightly different between sexes, so going by my experience again, this is probably a female as they are smaller than males. 

So, I better wrap this up as if you've made it this far through the post you’ll sure be getting really bored by now!

It’s a bloody Yellow-legged Gull for gods sake. Experienced gull watchers would be probably just go with that straight away but I for some reason enjoy going through every little detail, doubting myself, then eventually go back to my initial though. Anyway, that was an little insight to how I sometimes spend an evening! I think there’s something wrong with me.... I'm off to the pub. 

All quiet out on the Fleet...

I was right about this mornings weather and I did indeed have a lie-in but the wind seemed to drop a little after sunrise so trotted out to Clouds Hill in case something had happened over night. By something I mean an arrival of birds...

Well that certainly wasn’t the case! Not a single grounded migrant in sight or heard except for a single Ring Ouzel which was calling from some scrub near the access track. Saying that I really should include Song Thrush as a grounded migrant though. There seemed to be several around and I managed to count 7 at least and caught two in the few nets that I got open, the rest were closed due to the wind. This one was obviously a messy eater going my the bits of berry on its face! It had a lot more on the other side. 

This particular bird was aged as a 3, which means it was hatched this year. Note the four outermost greater coverts which contrast the inners. Nice and obvious unlike some species.

Overhead there wasn't much moving except for Skylark, which in the two hours 150+ went over. All were moving west. A pleasant surprise was amongst them was a single Woodlark which went over about 9:30ish calling as it went. Managed to get it in the bins as well. Only other birds of note were two Marsh Harrier and three Brent Geese which aren't that regular that far up the Fleet. Three Clouded Yellows were also notable, two of which came in off the fleet.

The wind seems to be a big issue from now on. Can’t see much ringing happening over the next week or so. Will be interesting to see what these southerly winds do. Hopefully a few nice moths but not sure what it will bring in terms of birds.

Getting to know the locals...

I've finally got round to clearing the rides and getting some nets up at my ringing site down on the fleet. I've not ringed much at all this year at Clouds Hill but fingers crossed the next few weeks produce some numbers. Yesterday evening whilst putting up the last few nets I stuck all the installed nets up to see what was about. Having not ringed there since the spring there were plenty of locals who wouldn't have encountered the nets before. Lots came to have a look and ended up with a lovely shiny new ring on their legs.

Wrens were plentiful!

As were the local Blue Tits

Both species ‘loved’ by ringers for their abilities to get nicely caught in the nets and the latter’s shear determination to rip your fingers off!

Usually as the season goes on the locals learn exactly where the nets are leaving all the oblivious migrant birds to bump into a net.

Hoping to go out in the morning but the wind at the moment suggest I might be having a lie in... Hope not as on yesterdays visit there was a rather interesting tacking call coming from the brambles. Not a tack call I’ve heard before so I’m intrigued to find out what it possible was. I got an idea in my mind but that’s all it is, an idea, at the moment. Might pop down for a few hours regardless tomorrow to see what I can find even if I don’t get the nets open.

To finish, here’s a shot of one of my favourite net rides. Usually my last net of a net round and a nice chance to look out onto the fleet!

The Dorset Moth Fair??!

Spent the day working at the Dorset Bird Fair over at Durlston Country Park. Birds were certainly in evidence but I must admit that the moths really made the day for me! Asides from a brief snatch of Richard’s Pipits call, a Hobby leaving Dorset was probably the best avian event. Yesterdays mothing efforts produced a couple of Crimson Speckled, a species which has been popping up at several spots over the last week or so. This has made me really want to see one so imagine my disappointment when there were none in the traps this morning! However, a rather excited BTO staff member came back from a stroll saying he’d seen a Crimson Speckled just a hundred or so yards away! Would it stay put though....

Well, that picture suggests strongly that it did... They are a pretty rare sight in this country with most probably originating from southern Europe or even north Africa! These southerly winds over the last few days certainly would have been responsible for this pretty stunning moth to make it to Dorset.

It was enjoyed by lots of visitors to the fair as was this beast. Another scare visitor to our shores.

A Convolvulus Hawk-moth, which is a fairly scarce immigrant moth though much more regular in the UK than the Crimson Speckled.

It was a great weekend and thanks to all over at Durlston for running such a good event!

Also, just a quick message to everyone who's moaned, had a go, or just politely asked about the water levels at Radipole. They are now nice and low and there's loads of mud. Just a Black-tailed Godwit enjoying it this evening but at least it's a start!
