Mediterranean Gulls in Edinburgh and Lisbon

Unringed adult Mediterranean Gull at Seafield, Edinburgh, 2 Aug 2013
Well, I hadn't seen a Mediterranean Gull this year so was pleased that a few were loafing on the sloping front at the Monument to the Discoveries in Lisbon earlier in the week. Just like buses, of course, as soon as I am back in Edinburgh another one pops up with this nice adult at Seafield today. That's my ninth species of gull at the site this year (GBBG, LBBG, HG, CommonG, BhG, Glauc, Kittiwake, Little Gull & Med) – here's to the tenth, whatever it may be!

New lens, old favourites

Young Jackdaw with 'brown' plumage mutation? One of two out of a hundred or so that were brown rather than black and grey
Took my new lens for a walk today. Was planning to buy it before I went to Malaysia, and while there were plenty of moments when it would have been handy, the thought of its first trip being into the haze of Sumatra was too much for me. So what did I test the L glass on - old favourites: corvids and gulls... Pretty pleased with the results...

Ah, one of my other old favourites - a lovely hooded Black-headed Gull
A juvenile Black-headed Gull - nice to see a couple of this year's young already on the wing

Gulls in stormy weather

The surf was really up as these Black-headed Gulls dodged the spray at Skateraw last Saturday. Next day it wasn't just the waves pounding - I had slipped a disc and the remainder of the week has been somewhat of a blur. Only today as the pain was subsiding did I remember this dark tailed first winter Common Gull from the same day. I don't think that is a particularly frequent plumage type - I'm hoping for one with a heavily barred rump as well and a nice short bill - i.e. the US species/subspecies Mew Gull...

More otter shots


This interaction was easily the highlight of my weekend - a Black-headed Gull swooping in to see whether an otter at Duddingston Loch had left it any fish scraps. The answer seemed to be no...

While this was an exceptionally prolonged view of an otter in Edinburgh, it wasn't the best view of an otter that I have had this year. Here is another shot from that encounter on Berneray during the spring. I am now very glad that I took this iphone shot of my imac screen to text to a mate - as I have since lost the original jpeg on a crashed disk :(. That is a scorpion fish by the way.

Far hiv ye bin ye Clarty-heided Scaffie



This Clarty-heided Scaffie (that's my completely made up Doric name for Black-headed Gull) had dropped into the sewage works at Seafield on Sunday. As usual my digiscoping skills deserted me when I needed them, but the code was very readable through the scope left-black-on-yellow-2XCL. If you haven't guessed it is from Aberdeen - it was ringed as an adult on the Ythan Estuary north of Aberdeen at Newburgh on 2 September. Amazingly, Stephen has seen 2XCN just a few miles along the coast. Ok, so the competition is on to find 2XCM!

Colour ringed Black-headed Gulls at Alnwickhill

I have been searching for readable colour rings on gulls at Alnwickhill for over a year. In that time I have only managed a single read - a Herring Gull in November 2010 (ringed in Gloucestershire). Other than that I have seen unreadable Herring Gulls and and some partially read Norwegian Common Gulls. Yesterday I had already had a typical encounter with a white-ringed (Norwegian?) Black-headed Gull on the Aberlady shore - it was too flighty and distant for its code to be read.

It was with a little shock then later at Alnwickhill that I noted that one of the nearest Black-headed Gulls was white colour ringed. As I set up my scope I was confused to see that the ring had suddenly changed both leg and colour! Wow, two colour-ringed Black-headed Gulls...




So, it turns out that the white-ringed JHR4 (on the right of the pictures) was ringed in Oslo, Norway, in March 2011 and the blue-ringed 2C13 (on the left) was ringed at Killington in Cumbria in June of the same year. Interesting that they should both be spending their time in winter in Edinburgh and a great surprise for me to find both at the same time.

White Christmas: adult Med Gull at Alnwickhill

Another quick trip up to Alnwickhill pays off with an unringed adult winter Mediterranean Gull dropping in to bathe and loaf around with around 100 Black-headed Gulls. Fantastically white winged in flight, the Med Gull has to rank as one of my favourite species; watching it float around in the blustery wind after bathing was particularly enjoyable - particularly as this was the trip to try out the Opticron HDF eyepiece with the Kowa TSN4 scope body. A stunning optical improvement just in time for a stunning gull.








Other Alnwickhill news is that the 5 Canada Geese and 1 hybrid Canada x Greylag Goose have been replaced overnight by 7 Greylag Geese!

Not so rosy

Had a quick check for ringed gulls at Alnwickhill this morning. Instead saw this unfortunate Black-headed Gull on one of the walls. It is not uncommon, of course, for gulls to have damaged legs or missing feet - injury due to predation or accident possibly.


Note the evidence in the photograph above of the Canada Geese that have taken up residence at the water works for the last week or so. Pic below from last weekend.


Most unusual sight today was a rose-flushed Common Gull. Too distant to make out any colour difference with the SLR, but clearly nicely pink through the scope. First one seen since last winter's bird, and it looked oddly apricot in the photographs - see here and here. Maybe I'll get a shot of it tomorrow. This pink flush is common in some gulls, but apparently relatively rare in Common Gull.

Edit 31/1/12: Just found this picture of a rosy Common Gull on a Norwegian blog: http://oslobirder.blogspot.com/2012/01/finallymed-gull.html

White p6 on Black-headed Gull

Had a weekend working in Stirling while others are seeing all sorts of exciting migrants further north in Scotland. Inspired, I headed to Alnwickhill as soon as I was back in Edinburgh. Well worth it too as there was a Black-headed Gull with nice white wedges with white primary 6s as well as p1–5s (see also here)! This seems to be an uncommon form, but even I'll admit it is not quite as exciting as a Sandhill Crane (well done on the pics JosephN - if they do not get Photo of the Week, I don't know what will!)!

Black-headed Gull variation

As I was passing through Holyrood Park this morning, I sopped briefly at St Margaret's Loch to see whether Edinburgh's resident Iceland Gull was still in the habit of hanging around at the lower loch in the morning before heading up to Dunsapie for the afternoon. Sure enough it was still there chasing the smaller gulls for bread. Nice to see half a dozen Lesser Black-backed Gulls back, always the first of the summer migrants to return to these parts.

In amongst the Black-headed Gulls this rosy individual with a flush of pink on its chest and neck was eye-catching. A well-documented variant in this species, it reminded me of the apricot coloured Common Gull that visited the back garden a few times during the winter. Both of these birds were more striking in the field than the photographs suggest...


First-winter Black-headed Gulls are also well known for the variation in their plumage. The following shots shows two contrasting birds - the individual on the left with much more melanin in the primaries, secondaries and primary greater coverts.


I only had a few minutes to try for that 'perfect' image of the Iceland Gull but somehow don't thibnk I managed that today?....

Icing on the cake: January's Lothian highlight

The first month of the year is coming to its end already, and I see on Bubo listing that I am well off the Lothian list pace. My running total of 88 species reflects a January with limited time for birding beyond my local patch. As a combined force, Lothian listers have logged 130 species in the county this year already and Tony O'Connor leads the current table up at 112. Of course, it is not a competition, I keep telling myself - just some fun. Nevertheless, quite a few of these should be easy targets for me in the next few weeks - I am yet to see Goosander, Whooper Swan or even Pochard. I also note that there are three species that feature on several lists that I have not yet seen in the county - Taiga Bean Goose, Green-winged Teal and Smew - maybe I should put some effort into seeing these in early February...

I did add a couple of new species today thanks to a deviation on the school run and a lunch hour in Holyrood Park, Edinburgh.

On both visits the Iceland Gull was showing well, on St Margaret's Loch in the morning and on Dunsapie Loch at lunch time. It could be enticed into flight with some carefully thrown bread crusts, though it seemed unable to compete with the screaming Black-headed Gulls for the scraps.

This bird is in first winter plumage, though this term is sometimes avoided for gulls like this one that have no post-juvenile moult (all the feathers here are un-moulted first generation juvenile feathers). The lack of moult may be related to the short nature of the Arctic summer. So what term would be better than first winter? Second calendar year (2CY) is maybe no better, given how different this bird will look in ten months' time, so possibly 'first generation' is best of all. Whatever we call it, it is certainly a strikingly beautiful young gull.

I had travelled to Galway in December in the vain hope of getting good views of this white-winged cracker. Little did I know that a month later there would be such an accommodating individual within a couple of miles of home!
The subtlety of the bird's markings could be best appreciated on the tail. The white primary feathers and long wings make this bird unmissable in flight.


The Iceland Gull could be tempted by bread, but it always seemed that little bit slower off the mark than the Black-headed Gulls and Common Gulls.
On the water, the long white primaries made the bird equally distinctive, and in good light, the bird's iris could be seen to be chestnut brown rather than black. This colour will lighten over the coming months to the very pale eye typical of adult Iceland Gull. The 2CY bill pattern already seems well developed.

Too slow to get to the bread, the bird started foraging, though it did not seem to be successful.
 
A great bird and one that I hope hangs around for the next few months...





Another bonus while feeding the gulls this morning was this Common Treecreeper in the trees around St Margaret's Loch. Another Lothian year tick for me.
















A Common Raven  over Arthur's Seat at lunchtime was a good bird for the city centre.

















Finally, here is a Carrion Crow with de-pigmentation showing that there is more than one 'white-winger' in Holyrood Park today!

Gulls: no-show Norwegian and Iceland

A quick trip up the road to Alnwickhill water treatment works turned in to a long stake-out today. Soon after I arrived one of my target birds dropped in to my field of view - a colour-ringed Common Gull! For most folk, this would probably not be the most exciting of events, but it is something I have been actively looking for locally over the last couple of months. Today's bird had a white ring with black lettering, but frustratingly it moved out of view just as rapidly as it appeared and I could not be sure of the combination. I'm fairly confident that the first letter was 'J', which could indicate that it was ringed in Norway. Three cold hours later the bird still hadn't returned and I returned home disappointed, but with the consolation of having seen my first Linnets and Lesser Black-backed Gull of the year, as well as some less regular species at the site: Great Black-backed Gulls, Goldeneye and four Waxwings.

Once home I found out that I had been watching the wrong Edinburgh water-bodies this weekend - a first winter Iceland Gull had been seen since Friday at Dunsapie and St Margaret's Loch in Holyrood Park. With the light beginning to fade I decided that it might just be worth the couple of mile trip up to St Margaret's. By the time I arrived, most gulls had flown to roost and only a handful of Black-headed Gulls were still at the loch in the twilight. Never mind, it will probably return, so I read some Mute Swan colour rings in the fading light.

As I returned through the park, I paused to photograph the sunset and was pleased to notice that there was a Northern Fulmar high up over Our Dynamic Earth. Another appeared and the two birds began chasing and interacting like a pair of giant swifts careering through the twilight. It may have been cold, but it was a warming reminder that spring is not far away.
