Of the 13 species of wild birds which may be killed under the 1981 Wildlife and Countryside Act, three are gulls but only if they are a danger to aircraft, farming or public health.

Either a special licence, whose execution is closely monitored and controlled by Defra, or a general licence is available to owners or occupiers of property but, in either case, the right to kill is limited to the licence-holder's property.

If a bird goes on to a neighbouring property or the street, to kill is unlawful.

Anyone killing a wild bird without a licence is liable to penalties up to a £5,000 fine or six months in jail.

Food brings gulls into built-up areas when their proper sea food is in short supply, as it is now in the Channel.

Residents and their council representatives must ensure food is not available in overflowing dustbins, plastic sacks and open rubbish-tips. Gulls are now on the "amber" warning list of species whose numbers are a cause of concern.

It is up to the public to see these magnificent birds are not killed or hurt.

If anyone sees threats to them, report the matter to the local police wildlife officer - in Brighton, PC Clasby.
