Colour-ringed Caspian Gull Update - Red 16P4

The Polish Bird Ringing Centre has replied very quickly to my report of the red colour-ringed Caspian Gull. It was colour-ringed as a chick on May 15th this year near Paczkow, Poland. Interestingly it was sighted by Reinhard Kunow on August 27th at Sierksdorf, Germany.

Last Visit to Shawell for 2014

I couldn't resist one more visit to Shawell before the year's end, so yesterday morning I donned my thermal underwear etc, and trotted off.

This was the first day the tip was up and running after the Christmas break and obviously most of the gulls had got the memo, as plenty had turned up for the feast.

I spotted a first year gull swimming in the shallows and I spotted it had a red colour-ring. It took ages for my Jedi mind tricks to will it to climb out of the water, but eventually it obeyed me. My first impression of the gull was that it might be a Caspian Gull or a hybrid. 

It wasn't a classic but the more I looked the more I thought it could be a Caspian Gull. It was impossible to read the colour ring as it was wet and the sun was reflected by the water. The only figure I could read was a 1. Something spooked the gulls and I lost it amongst the hordes.

Luckily I soon found it again amongst  a group of gulls resting on the shore slightly closer to my position. It didn't land on the shore, but stood in the shallow water at the edge.

Review of the Gulls at Shawell During 2014

During 2014 my fascination with gulls at Shawell continued unabated. The standout highlight for me was finding three juvenile Caspian Gulls during August. The subtle differences between the juveniles of other similar species and Caspian Gull juveniles take time and practice to appreciate.

My total gull species recorded was up by one this year thanks to a sighting of a Ring-billed Gull. In all I recorded 11 species and of these six were seen on most occasions. 

I made visits during each month and found once again that there is no gull season, as interesting gulls can turn up at the site at any time.

All gulls found by myself unless indicated otherwise.

Christmas Greetings

Before I start eating and drinking, I would like to thanks all those who have stopped by to read my blog or look at the pictures during 2014. I would also like to wish you all a Happy Christmas and a Prosperous New Year - Ave a Good Un!

Iceland Gull Again

Herring Gull numbers are building up and just as in late December 2013 there are at least two thousand visiting Shawell at present. The throng of gulls at the tipping area is a wonder to see, but it is not a great place to practice your identification skills, as the gulls are constantly on the move. A first year gull with a soft brown overall colour and brownish tertials and primaries grabbed my attention for about two seconds before it was sucked up into the mass of gulls. Anyway whatever my first impressions were I never saw that gull again. On the periphery of the tip I did see a smart first-winter Yellow-legged Gull that had solid brown coverts and tertials that contrasted nicely with its grey saddle. I had not seen a first-winter for a while, so it was good to see another.

There was no sign of the Iceland Gull that I found on Wednesday at the tip, so it was time to move to the A5 Lagoons and hope for better luck. It didn't take long to find a smart fourth-winter Caspian Gull - a new one.

Fourth-winter Caspian Gull

This Caspian Gull was a real classic: a super slender long bill, a small head with a pair of dark eyes and an almost fully adult set of primaries. It hung about on the largest lagoon for over an hour, which gave me plenty of time to study it.

At dead on 11:00 something, probably a Common Buzzard, caused the gulls to panic and amongst the first group to settle back down on the water was the third-winter Iceland Gull. It must have been hiding on the other lagoon.

Almost as soon as it arrived it flew off again. It then returned briefly at about 11:30 and flew off again only to return about 15 minutes later. This time it stayed for about an hour.

The light was brighter today, which made the Iceland Gull look much more ghost like. Remnants of the immature plumage were still visible on the tertials and greater coverts. The paleness of the eyes was easier to see today as well. The legs are pink, but in certain lights they look a little paler than normal for Iceland Gull.

After the Iceland Gull departed, I noticed a striking gull near the shore that proved quite challenging. It was as clean looking as the adult Yellow-legged Gulls are at present. However, its head shape was wrong and so was its primary pattern. Its head was quite small and its bill was very long. The bill was a similar shape to a Herring Gull's, but it seemed too long. Its legs were a pasty yellowy orange, not right for Yellow-legged Gull. This gull may well be a hybrid Caspian x Herring Gull, but it is difficult to be 100% certain - what do you think?
