Bus pass boys at the beach

The “Bus Pass Boys” are a group of birding pensioners, two of whom are ringers. We make regular visits to Great Yarmouth beach in Norfolk to read colour rings on Mediterranean Gulls, some of us since 1999 (when we didn’t possess bus passes!). Our first birds are on site from about mid-July and most are gone by mid-March.

We have identified nearly 100 different Mediterranean Gulls that were ringed in 10 different countries. They have originated from Belgium, Germany, France, Poland, Britain & Ireland (only two), The Netherlands, Denmark, Czech Republic, Hungary and Serbia. There have been multiple sightings of many of these gulls (click here for a complete ringing scheme overview of recoveries for Med Gull). Many valuable life histories have been identified, with some of the birds mentioned above having also visited Spain, Portugal and The Azores.

Some of our Mediterranean Gulls have been shown to reach a ripe old age. Two of the birds we have seen this winter were originally ringed in 2001, one of them already three years old when ringed.

The BTO were impressed with our efforts and they suggested in 2013 that we should have a “joint venture” to try and cannon net some of these birds and fit them with British colour-rings. Very few Mediterranean Gulls are ringed in Britain so we took this as a challenge! Our aim was to add to the pool of ringed birds at Yarmouth and to further understand where these wintering birds originated. Maybe British breeding birds are there – we just didn’t know.

It wasn’t as easy as we had hoped. It is well known that Mediterranean Gulls are more intelligent than the people trying to catch them (most are also better looking!) At time of writing we have caught and ringed 46 Meds and had 'our' birds seen in The Netherlands, Belgium, France and Poland. We have also establish that some British-breeding Mediterranean Gulls winter at Great Yarmouth.

Last week we received notification of a sighting of one of our birds that was truly spectacular. The bird had been ringed at Great Yarmouth on 22 November 2015. It was seen on the beach until the end of February 2016 then disappeared for the summer. It had returned to the beach by the end of November 2016 and remained until at least 18 February 2017. Remarkably it was next seen 15 April 2017 at Trostenetskij Rubbish Dump, near Minsk, in Belarus. ‘Our bird’ was apparently paired with a colour ringed bird ‘red PKU6’ which was ringed in Poland.

This represents the first British or Irish Mediterranean Gull that has been reported from Belarus and it is the most easterly sighting of any of our Mediterranean Gulls.
