Residents on a Perranporth street plagued by aggressive gulls, seen attacking their postwoman, are calling for the birds to be culled.
On Monday Royal Mail suspended its postal deliveries to Liskey Hill Crescent because of the health and safety risk to its delivery workers.
Residents have been told to collect their post from a nearby post office.
For the past five weeks residents have watched in horror as nesting gulls swooped down on the postwoman during her daily rounds.
Eric Hardinge, (CORR) who moved to the crescent 20 years ago, said the birds are becoming a serious problem.
He told the West Briton: "In the past five years the seagulls have become more aggressive. They are protecting their chicks and attack people in packs, swooping down, targeting people's heads.
"They go beserk when they see bright colours which is why I think they've gone for the postwoman because she wears red."
The birds have also attacked dog walkers, said a local builder, who saw them "dive bomb" a woman who screamed in fright.
In a letter to residents Royal Mail's delivery office manager, Andy Blight, said the service would resume once the chicks move on, or if they are removed by an authorised person.
The letter stated: "..a member of staff was attacked whilst delivering mail to numerous properties within your area by seagulls protecting their chicks...This exceptional step has been taken in order to safeguard Royal Mail employees."
Despite repeated calls to Cornwall Council and pleas for help to Perranzabuloe Parish Council, Mr Hardinge said no one is interested in tackling the problem.
He added: "The chicks will disappear but it is an on-going problem. I can understand why they've stopped our deliveries, but the birds need to be culled. They've become very aggressive, behaviour which is being passed onto their chicks."
Stuart Little, who has parkinson's disease, moved to the crescent three months, and said he is not able to collect his post.
He said: "I can't walk very far. I understand the reasons for stopping the service but it's very inconvenient. I think the gulls need to be controlled, they're a pest."
