Caspian Gull X307

 

UPDATE! JAN 2020  – After seeing images of this bird as a 2nd, 3rd and now 4th winter Im more inclined to call it a hybrid rather than a decent Caspian Gull. It looked pretty standard German Caspian as a 1st winter as you can see below but as the bird has grown is has developed a few less than desirable features which are more Herring than Caspian;

  • The amount of black on p10
  • short or none existent grey tongues in the longest primaries
  • Paling Iris
  • pale mantle

Below is the post as i wrote it back in 2016:

Today I received the ringing information for a 1cy Caspian Gull found on the foreshore at Thames Barrier Park on the 25th of September. 111 days and 970 km west of its birthplace.

The bird was rung as a chick at Reddern Germany, near the Polish border on 06.06.16. Hatched into a 80% Caspian 20% Herring Gull colony.  A couple of heavily marked second generation scapulars as well as faintly notched first generation scaps could be an indicator of mixed ansestory at some point, however the replaced feathers are brand new, adding to the bold pattern and as far as i can see are within variation of the species. It’s worth pointing this out if the colony is known to be mixed and its impossible to say for sure. For more pics of this bird click here

Scillies 2016

Whilst the North East of the country was being showered in Siberian vagrants and rarities, the opposite end of the was slightly behind in avian terms. However a few great birds and many close encounters with species not so often seen by London patch watchers, plus very good company and pretty much constant clement weather made for a great trip.

A surprise find and a first for Scilly! was my personal highlight- this gleaming 1cy Caspian Gull dropped in front of me for a matter of seconds on the rising tide at Porth Killier/Browath, accidentally flushed by fellow house mate and Larid loather Lee Amery along with 30 or so Lesser Black backs towards Gugh, the latter species were present in notably higher numbers the day that the Caspian arrived. The bird wasnt seen again although number of Mary’s birders were high the following day.

Due to occasional showers and an aching back, i didn’t always have my camera on me, but a few choice birds around the island were showy enough for a few shots now and then.

Firecrests were seen and heard most days.

A few Spotted Flycatchers were seen over the two weeks, including this 1st year bird that littered the ground under its perch with Red-Admiral wings.

At times there were up to 6 Black-Redstarts on Periglis beach, with a couple of lone birds dotted about the island

Yellow-Browed Warblers were a daily occurence and seemed to fluctuate in numbers during the two week stay,  some days seeing 10+ on Agnes alone.

There were two Red-Breasted Flycatchers in the Parsonage, a British tick for me! After a few near misses over the years.

The last chance saloon!  this Red-Flanked Bluetail gave myself, Laurence Pitcher, Graham Gordon and Lee Amery (finder) a private show away from the crowds on our final day. Stoked for Lee for finding one of the last few BBRC Bluetails as it comes off the list this year apparently.

Just before the news of the Bluetail broke, the beginning of a long and widespread story began. Laurence Pitcher and I were handed a dead ‘Yellow-Browed Warbler’ by Islander Fran Hicks that had flown into his window at the lighthouse, the crazy story goes on from there and can be read in full here

A great two weeks away from the patch, although I hardly felt away from it with fellow Walthamstow enthusiast David Bradshaw being an October feature on st Agnes for many years.   Lovely people and lovely birds even the ones i missed out in this quick summary. But i’ll be spending more time year on this unique Island for years to come.
