Hybrid Herring x Lesser Black-backed Gull in Edinburgh

Probably the best shot showing the ring on the right leg - palish yellow legs and mid-toned grey uppers

Hybrid gulls... By looking closely at the gulls of Edinburgh and Lothian over the last couple of years I've seen quite a few probable Herring x LBB Gulls without yet connecting with a YLG or Caspo. I was seriously considering making 2014 a hybrid-gull-free year by taking a beak from the search for southern European larids in and around Edinburgh. Well, what do you know, a hybrid argentatus x fuscus seems to have taken a shine to the grassy pitch outside my office window in Merchiston. It has been there for the last two mornings, but has disappeared before the light has been good enough for decent photographs. Even with my DSLR on hand this morning the shots are poor. Both days I have seen it in direct comparison with Herring Gulls and a single Lesser Black-backed Gull. Its mid-tone mantle and upperwing plus yellow legs are distinctive. Excitingly the bird is ringed on its right leg - although it will take a miracle to get close enough for a ring read I would imagine.

A poor shot in the low light levels - but the wing-tip pattern can just about be discerned - a narrow band on P5 and typical pattern for hybrid

2013 Highlights

As the year draws to an end I am surprised by just how many amazing wildlife encounters I have managed to fit in. Here's to 2014 being just as exciting for us all.

Finally, to gulls

Grey Phalarope at Skateraw

I was heading out to Belhaven again to try for the Caspian Gull seen on Friday when news broke of this lovely little wader just a little further along the coast at Skateraw. I was delighted to see it was present and performing as I haven't had much luck with twitching this year... still irked by the unreasonable behaviour of the two Northumbrian Ivory Gulls... After watching the Grey Phalarope for half an hour or so I tried again for the gull at Skateraw tip and Belhaven. After a good few hours at the latter site, where the highlight was a Greenshank, I headed back and had a bonus Merlin from the A1 as I passed the Blindwells area. Not only was the Phalarope a Scottish/Lothian tick for me but the falcon was the first in 2013. Nice though to see so many of the Lothian bird-finders out and about today - keep it up guys, maybe I'll pay you back... I'm hoping for a much better run in 2014...

Patching: Kingfisher and Wigeon

I decided to stay close to home today. Now that the leaves have fallen I have been able to peer towards Little France when passing Craigmillar Castle and have been surprised that the building works area has actually been turned into a flood prevention scheme - bingo! a whole array of previously un-noticed birding habitat!

A quick look around this morning produced a nice selection including 25 Lapwing, 23 Stock Dove, Skylarks, Reed Buntings, Linnets and Meadow Pipits along with a handful of loafing gulls. Most surprising was a total of 98 Mallard, 4 Teal and patch ticks in the form of a Kingfisher and 2 Wigeon.

Sub-adult hybrid Herring x LBB Gull, Skateraw, 15 December 2013

 

 

I had only commented on Twitter yesterday that I had been unable to find a hybrid gull in Edinburgh for a few months (despite looking hard) when I picked one out at Skateraw Landfill site East Lothian today. Viewing is distant and the images poor. Aging these subadults is hard as I am pretty sure they follow their own rules in terms of plumage. This individual has white underparts and tail and a clear trailing edge on the open wing but signs of immaturity in the coverts and tertials.

Identification of 1st winter large white-headache gull

 

Oh no! Its a snouty, pale under-winged, venetian-blind upper-winged first-winter large white-headed gull... Maybe some Caspian Gull genes in there but if so it does not quite look like what it should look like. Best then to ignore the cachinnans-like coverts and tertials and put it down as a weird argentatus Herring Gull. After all - every gull at Seafield is a Herring!

Never did see the tail...

Harried Harris Hawk

Carrion Crows and CarrionxHooded hybrids hassling the Harris Hawk

A couple of brief trips to Seafield so far this weekend have produced a couple of interesting sightings. Yesterday an adult Mediterranean Gull was offshore with the Common Gulls at the outfall. Only a brief and distant sighting sadly. Today's unexpected bird was another view of the falconer's Harris Hawk on top of one of the buildings. The gulls seemed to be slightly worried. The corvids on the other hand were flocking in droves to get a good look at this tropical species.

There were a couple of regular hybrid crows joining in this attempt at mass bullying. Earlier I had seen what could have been a pure hoodie over Duddingston but of course it is far more likely to have been a hybrid. Here is a nearly-pure Hooded Crow hybrid on Seafield shore earlier in the month.

River Otter off Musselburgh

I arrived at Musselburgh sea wall today just at the right time today. Another observer had just found an Otter offshore. We scoped it as it headed in the general direction towards Fisherrow Harbour. Distant views for me - but enough to get good looks at its head tail and body out of the water each time it surfaced and dived. We rushed around towards the harbour by car but sadly could not relocate it.

My best River Otter sighting of the year is shown above - an amazing, prolonged close view of an individual feeding at very close range in a river in Andalucia in July. A few minutes later I also saw my first ever Black Stork!

Steel grey Scandinavian Herring Gull

I can't be sure without a colour ring, but I think that this Herring Gull has crossed the North Sea for its winter break in Musselburgh. The steel-like grey upperpart tone combined with reduced black in their outer primaries are pointers to the identification of Scandinavian Herring Gulls. Another bird at Seafield this morning was darker grey and had thayeri-like wingtip pattern - that's a classic combination for a northern argentatus. This one is slightly trickier on both counts, so maybe its origins are slightly less far north?
