Gareth could do with more volunteers on the gull roost survey. I have repeated the article below.
The last coordinated count of gull roosts in the CWP was undertaken in winter 2005/06.
In conjunction with the BTO Winter Gull Roost Count in 2003/2004 and a series of casual observations, the data confirmed that the CWP supported an increasing winter roosting population of gulls, in particular black-headed gulls, common gull, lesser black-backed gulls and herring gulls, with smaller numbers of med gulls, yellow-legged gulls, greater black-backed gulls, Caspian gulls etc and occasionally a white winged gull to liven things up.
Furthermore these surveys highlighted that the CWP supports, in winter, an internationally-important population of lesser black-backed gulls, which at the time equated to over 5000 birds. An update to this work is overdue – a lack of recent counts is leaving a large gap in our knowledge of how these species use the CWP today, not least in response to changes in lake use across the CWP.
On Sunday 21st January 2018 (the January WeBS date) we hope to undertake a coordinated count of sites across the CWP; to do so will require a large team since there are a large number of sites and some sites are large enough to require more than one observer. We may require a team of around 30 people to achieve full coverage, but obviously some compromises may be necessary – focus will be upon covering the core sites.
If you’d like to get involved in this please let us know.
Experience of counting gulls is of course a pre-requisite; whilst the focus is on the more common and widespread species in order to maximise counts of these, there is of course the chance of encountering less common species too. All of the data will be contributed to the BTO’s Wetland Bird Survey and will therefore contribute to various population estimates.
More details will follow nearer the time once we know how many people are interested in getting involved. Many thanks – Gareth Harris. Local Organiser for Wetland Bird Survey in the CWP.
