Great White Egret

I couldn't make it out first thing this morning, so Adey went over to Brascote without me. Around 09:30 he sent me a message to say he had found a Great White Egret. Not quite the rarity it was but still a good bird for the South-West Leicestershire list. In fact it is only the third record for the area.

We still await a Cattle Egret but in the meantime this will do.

I managed to get over about an hour later and it was still there.

It was wary and easily scared. At one point it flew towards Cadeby Quarry, but returned after just 10 minutes.

Caspian Gulls at Shawell

I'm pretty sure my Caspian Gull haul today was my best day count so far at Shawell. Herring Gulls were already the most numerous species. This is noteworthy as they generally don't take over from the Lesser black-backed Gulls until December.

In total I recognised 13 different Caspian Gulls: nine first calendar-years, two second calendar-years and two third calendar-years.

First Calendar-Year Caspian Gull - note how far its moult has progressed. Some tertials and greater coverts have been replaced with second-generation feathers.

Some of the gulls are photographable as they leave the sandpit and head off over Gibbet Lane. I struck lucky again when one of the colour-ringed birds flew over me. LU4T was ringed at Pitsea Landfill site on 20th November 2013. It has previously been seen in France.

Back to the Algarve

I couldn't resist another visit to this great location. If you enjoy looking for your own birds then this is a great destination. Even in the seaside towns you can find interesting migrant birds such as Pied Flycatchers. Dawn and I managed a decent total of 159 species, which was just four short of our best total. I have now seen 229 species in southern Portugal. New birds included Red-breasted Flycatcher near Sagres and a Bullfinch on a wooded hillside.

One of the highlights of my October trips is the boat ride out of Sagres looking for seabirds. It wasn't a classic trip, but we did get really good views of Cory's Shearwaters. The wind was quite brisk, so we had to hold on. A couple of Sooty Shearwaters also put in an appearance, but Great Shearwater escaped me this time.

After the boat ride a trip to the raptor watchpoint at Cabranosa is a must. Luckily the raptors were arriving and they were relatively low over the watchpoint. The highlight was a wing-tagged juvenile Egyptian Vulture (2MW) that had been ringed near Jaca, Spain (The Pyrenees).

As you know, one of the reasons for my trips to The Algarve is for close up studies of gulls. We visited Quarteira a site I'd overlooked in the past. This site proved excellent with plenty of colour-ringed gulls plus a giant Great Black-backed Gull,. Oh and another Azorean Gull candidate.

The highlight for me of the colour-ringed birds was a first calendar-year lusitanius Yellow-legged Gull (A82:G) from the Basque Country in Spain.

A visit to the Alentejo region between Castro Verde and Mertola is a must for birders visiting The Algarve. Not natural Steppe, but the man made Cereal Steppe is a home to many species found in the natural environment. Great Bustards are usually easy to find, but this time we struck lucky with a single Little Bustard as well. Large birds of prey come out on to the plains to hunt, but they can be very hard to find. The church called Ermida de Nossa Senhora sits on a hill side near Monte Salto and it's a great point from which to scan for large raptors. A little luck is needed to time your visit when raptors are close by, but this time we had got it right. Within a few minutes of arriving a group of Griffon Vultures appeared and amongst them were three Iberian Imperial Eagles - including one of this year's juveniles. Dawn and I watched the juvenile tussling with one of the older birds.

At one point the juvenile flew down and landed in a tree below the hill.

We also saw Golden Eagle, Bonelli's Eagle and Egyptian Vulture.

I haven't seen many Great White Egrets in The Algarve, so two over Olhao was a treat. The photo below looks more like an X-ray.

I can't wait to go again...

Update from Shawell

This is a good time, as lots of gulls are passing through Shawell at present. Over the weekend, including Friday afternoon, I read over 50 colour-rings, which is very good for the site. A few old looking colour-rings were amongst them, so I'm looking forward to receiving the replies.

It's always pleasing to photograph a gull inflight only to see it has a colour-ring. On Saturday afternoon I called out Caspian Gull as a gull sailed overhead. Steve Nichols was perhaps understandably a little un-convinced. Well when I reviewed the photo later I could see it was wearing a German colour-ring XCCL - a Caspian Gull - although I couldn't check its DNA as it flew over 😊

The next bird that flew over was a young Lesser Black-backed Gull and you guessed it, it was also sporting a nice colour-ring. DCUB ringed in Suffolk this summer.

Caspian Gull numbers are slowly increasing with first calendar-year being the most numerous (although very small numbers). A couple of adults have been around including a real beast that made even the Great Black-backed Gulls look nervous.

An Obsession with Baltic Gulls

Since I started watching gulls regularly at Shawell in 2012 I thought the possibility of an identifiable Baltic Gull Larus fuscus fuscus turning up there seemed good. However, only colour-ringed birds are acceptable in Britain - oh and some 2CYs. At the time no 2CYs had been accepted in Britain, but maybe it would be worth reading up on them?

From time to time a jet black adult LBBG caught my eye, but there is quite a lot of overlap in features between fuscus and intermedius and so a positive identification of a vagrant is near on impossible. My first opportunity to claim a Baltic Gull came in 2014 when I saw J727 a Norwegian ringed Baltic Gull, but I didn't nail the ID that time and I missed the full scientific name whilst entering the ring reading.

My skills were improving all the time and in July 2015 I saw a second calendar-year LBBG on the landfill that shouted Baltic Gull! It had a full set of unworn new looking primaries, many black adult  like scapulars and coverts. Its greater coverts were plain brownish with no barring. Without going on, it matched the Altenburg Criteria for the identification of Baltic Gull in 2CY plumage - the only age when, from a vagrant point of view,  they are unique enough to be identified without a colour-ring from a known breeding area. I reported the sighting to the British Birds Rarities Committee (BBRC) in the hope that it would prove acceptable.

In March 2016 another go at J727 presented itself and this time I identified it as a Baltic Gull. I had forgotten about my 2014 sighting, but as the record appeared on the screen of my phone I couldn't believe I had seen it before. The scientific name was L. f. fuscus, so my ID was correct. I submitted the record to BBRC, but due to some issues over Norwegian Baltic Gulls the record sat in the pending tray. A record of a colour-ringed bird (J154) alleged to be from Horsvaer was causing some controversy due to it looking too pale for a Baltic Gull. The photograph of this bird did the rounds on Social Media, which did nothing to promote any goodwill for the 'Horsvaer gulls'. Because of this I did not submit a sighting of another Horsvaer colour-ringed bird I saw shortly after the sighting of J727.

I discussed this issue with Morten Helberg in Norway, who has ringed many of the 'Horsvaer gulls' and been involved in the study of these birds. Morten invited me to see for myself, so in early August 2017 Morten and I visited Horsvaer. We ringed over 60 chicks and looked closely at the gulls. We decided that we should report what we jointly knew about these 'Horsvaer gulls'. Our plan was to publish it in British Birds.

Baltic Gulls, Horsvaer, July 2018

Morten convinced me to be the lead author and along the way we recruited Mars Muusse from The Netherlands who knows loads about Baltic Gulls. In all it took a full year from start to finish, but I'm very pleased with the result. We submitted it to BB in January 2018 and Roger Riddington seemed very positive. He sent it to various reviewers in Britain and elsewhere in Europe. The consensus was that it should be accepted for publication. However, there was a small list of comments to address. The biggest issue was that a photograph of J154 was added to the paper with a question of how does this fit in with what we were saying!

We addressed all the issues and then a couple of really good things happened. Firstly one of the chicks we ringed in 2017 decided to visit Sheffield and it ticked all the boxes for moult strategy of 2CY Baltic Gull. Next we managed to get hold of the original photo of J154 and it turned out that the code on the colour-ring actually read JT54. It looked like J154, but not all of the code was visible and the top of the figure that was read as a 1 was missing due to the angle, but on the underneath of the colour-ring the top of the T was just visible. JT54 is an intermedius bird from southern Norway not from Horsvaer - I was very happy when I spotted the top of the T 😁. The bird claimed to be J154 never sat well with me, as on my two visits to Horsvaer I had not seen a similar looking bird.

I'm proud to say that the paper appears in this month's BB and hopefully the 'Horsvaer gulls' will now be taken seriously in Britain.

In July this year, I was checked the BBRC work in progress file for some Leicestershire & Rutland Ferruginous Duck submissions and at the same time I couldn't resist checking if there had been any movement on my Baltic Gull submissions. I gave quite a cheer when I saw that they had accepted my 2CY Baltic Gull from 2015. They had also accepted two others: one from Norfolk and another from Suffolk. At the time of writing mine is the fourth for Britain in date order.

Again I am really pleased by this.

Who knows where this story will go but Morten and I are already talking about another project...
