Hi John --- sorry just seen this! I'd agree with Herring Gulls

Hi Julian — I am currently preparing a report on gull roost numbers at Bewl Water in relation to similar water bodies across the UK, in response to a planning application. I wondered whether you had access to any latest figures for Chasewater...? Any help would be much appreciated.

Thanks! Yes it's legible and we've managed to get details on it. Fledged within Sussex.
