Pigeons have been found lying dead in their droves around the centre of Wells, in Somerset.
Many of the dead birds were found scattered on rooftops, in fountains and around the historical Cathedral Green.
It has sparked fears of a widespread epidemic.
And birds falling from the sky is seen by some as a sign of the end times as foretold in the Bible.
Birds were also pecked to pieces and half-eaten by other animals and birds including seagulls.
“The whole world is in danger of falling apart”
Rabbi Avraham Arieh Trugman
Former Mayor of Wells, Celia Wride, suspected something strange was happening in the city after members of the public reported sightings of dead pigeons on pavements and roads.
Mrs Wride said: “For the last few weeks, dead pigeons are appearing everywhere.
“One lady found three dead in her garden and my daughter and I saw one late one evening just lying on the pavement near our house.
“They have no apparent injuries and are intact.
“Several ladies told of an incident where one poor bird fell out of the sky and landed on a lady carrying a cup of coffee.”
Mrs Wride went on to rule out foul play but speculated the reason behind the deaths could be due to a parasitic disease.
“According to my local informant who is also the current Beat Manager, PC Dan Williams, we have discovered what may be the cause – ‘canker’.
“The RSPB say that the disease is easily passed within the pigeon population as they are such sociable creatures.”
Canker is caused by a tiny organism called a protozoan. It is a disease that is easily transmitted from bird to bird.
Pigeons pass it to other birds when they share water bowls, exhibit billing with other adult pigeons and feed young pigeons crop milk.
Signs of canker include weight loss, lethargy and bleeding from the mouth.
Symptoms worsen if the disease is not treated and in most cases will result in death.
Others have however given a more Biblical explanation for the strange phenomena.
Birds have also begun falling from the sky in Adelaide, Australia, with flocks plunging to earth bleeding from their eyes and bills.
Scripture in the Book of Zephaniah, from the Hebrew Bible, describes how God will “sweep away the birds of the sky”.
Rabbi Avraham Arieh Trugman described the phenomena as a chance to put the Earth back into balance before the end times and the coming of the Jewish Messiah.
He said: “If we see birds falling out of the sky, we should understand that if the environment gets too much out of kilter then the whole world is in danger of falling apart.”
Mass animal deaths have been reported worldwide this year – including 60 dead whales washing up on a beach in Iceland.
Thousands of fish also died in a lake in Indonesia, and 3.3 million pigs were killed by swine fever in Vietnam.
And some 15,000 birds fell from the sky due to avian flu in Mexico.
Meanwhile, a man confused for the Second Coming of Jesus Christ appeared in Kenya.
