Another Glaucous Gull

The place I am allowed to view the landfill site is useless in the morning if the sun is out. This morning I arrived just before the sun was above the horizon. Many gulls were already feeding and amongst them a juvenile Glaucous Gull appeared. There wasn't much time, as the sun was starting to make viewing difficult despite still being hidden. It was a smaller individual than last week's and its mantle was noticeably pale. I was able to take a short bit of video to at least record it. John Judge confirmed that out of the two juveniles roosting at Draycote Water one was smaller and paler on the upperparts.

For best viewing of the video change the setting to HD.

Caspian Gulls were in short supply this weekend: only one adult was present in a field near Shawell Village and a first-winter was in the same field, but that one was most likely to be a hybrid. Its greater coverts were a bit too chequered for my liking and its scapulars were a bit heavily marked too.

Last week I made one visit to Shawell and managed to see three Caspian Gulls, two adults and a third-winter.

A Great Day

I was fired up this morning and determined to have a good day. The forecast didn't look good, but he who dares and all that. 

I started the day scanning through the gulls resting in the massive quarry. I didn't count the Herring Gulls, but there may well have been up to 3000 present. A lone third-winter Caspian Gull was amongst the first group, but surely there must be more? Sure enough by the end of the day my total had reached seven, which may well be a record for Shawell. The adult I saw on Thursday was still present, but pride of place goes to the four first-winters that helped brighten up a dull day. First-winters in January and February can be really smart looking.

I pride myself on almost always getting a record shot of my best bird finds, but the record shot I got today stretches the title record shot to the limit. A juvenile Glaucous Gull was resting by one of the distant pools at Cotesbach Landfill site. No problem viewing it through my 70 power scope (some sort of fancy American/Swarovski speak ;-), but photographing it was a different prospect. Who can argue with the result?

As well as a record breaking seven Caspian Gulls I also saw another German ringed gull, however, I could only read three of the four letters that made up the code. It was either a hybrid at the Herring Gull end of the scale or a Herring Gull. Hopefully the scheme coordinators can pin point which bird it is.

More Caspian Gulls

I was out near Shawell at lunchtime, so I grabbed half an hour at the lagoons. There is a huge gathering of gulls there at present benefitting from Christmas waste being delivered to the landfill. No 'white-winger' yet (they will come), but there were three smart Caspian Gulls, including a belter of an adult, on the lagoons.

Third-Winter (4CY) Caspian Gull - Look at those legs!

Second-Winter (3CY) Caspian Gull 

Colour-Ringed Hybrid Caspian Gull

Amongst the gulls at Shawell today I spotted a third-winter with the look of a Caspian Gull about it. However, it wasn't a classic and its short wings and slightly odd shaped bill left me underwhelmed.

It was having a wash and brush up and every now and then it would flap its wings hard enough to get it airborne for a few seconds. As its legs left the water I noticed it had a German green colour-ring. Eventually it flew to the shore and gave me a few seconds to read its colour-ring before it flew to the bank between the two lagoons.

Its colour ring read XZDX. I emailed Ronald Klien in Germany and he replied quickly (technology is quite amazing as I did that whilst watching the gulls). XZDX was considered to be most likely to be a hybrid and my observations agree with that. It looks like it has a bit of Herring Gull blood in it.

XZDX is quite a traveller as you can see from its life-history that is displayed below:
