Silbermöwe
In the UK, the species, when taken as a whole, is declining significantly across the country, despite an increase in urban areas. The UK European herring gull population has decreased by 50% in 25 years and it is protected by law: since January 2010, Natural England has allowed lethal control only with a specific individual licence that is available only in limited circumstances. Natural England made the change following a public consultation in response to the Royal Society for the Protection of Birds in 2009 placing the species on its 'Red List' of threatened bird species, affording it the highest possible conservation status. (Previously, killing the species was allowed under a general licence obtainable by authorised persons (e.g. landowners or occupiers) under certain circumstances (e.g. to prevent serious damage to crops or livestock, to prevent disease, or to preserve public health or safety) without requiring additional permission beyond the general licence.)
