Around 190 pigeons were found dead in Ahmedabad city of Gujarat in over a period of two days, said officials on Thursday. Bird flu is been suspected as the probable cause of death in these pigeons.
Dr Rajendra Patel, assistant director, animal husbandry department, Ahmedabad district, said, to ascertain the exact cause of death of the pigeons in the Narol area, two carcass samples were sent to a Bhopal laboratory for testing for avian influenza.
“Around 190 pigeons were found dead in the Narol area of the city during the last two days in a suspected case of bird flu. We have discarded the carcasses as per protocols and sanitised the area.
“We have sent two samples to a Bhopal-based laboratory for confirmation (of bird flu),” said Patel.
Bird flu cases were first reported in Gujarat on January 8 when samples of some dead birds, found near a dam in Junagadh district, later tested positive for avian influenza.
Later, bird flu cases were also reported from Surat, Vadodara and Valsad districts, where samples of dead crows returned positive tests for the virus.
Bird flu is a highly infectious and severe respiratory disease in birds caused by the influenza virus.

It has been happening for about 3 weeks now . On the Roman coast there is a strange death of birds, from turtle doves to pigeons. In a period of pandemic, nothing can be underestimated, much less mysterious animal deaths.
“For some time we have been witnessing a really strange phenomenon – says Mario Russo D’Auria , president of the Progetto Futuro association, a hunter with breeding and cultivation experiences in Fiumicino -. We find turtle doves with no more energy, dying.
They do not have the strength to fly, they cannot get away from man when we approach the ground. It is not a natural behavior for turtledoves, far from it. And shortly after we find them dead on the ground. Those that mice or other animals that frequent the drainage canals do not take away with them “.
We are not talking about a single episode, nor about a limited number of victims, nor about a phenomenon that happened in a short time. “By now – explains Russo D’Auria – it has been happening for weeks . And I am available to the local health authorities if you ever want to investigate the situation ”.
In support of Mario Russo D’Auria’s worried statements, there are reports in the countryside between Ardea and Aprilia, a few kilometers south of Fiumicino. A sudden death of pigeons involved the whole area. A dozen in all, with findings quite distant from each other.
What is happening? Is it a natural phenomenon or should we worry? Are they toxic substances scattered on the land and therefore poisoning or viruses? For now the alarm has been raised, now it will be up to the authorities to clarify.

Dozens of pigeons fall dead in Valencia, Spain
A killer disease is taking a disastrous toll of wood pigeons in North Antrim.
At the time of writing the disease has not been definitively identified, but farmers and shooters have told me that in a three miles pigeon flightpath between Glenann and Glendun hundreds of dead pigeons can be found lying in the fields.
On Tuesday of this week I found a pile of pigeon feathers in Paddy McCurday’s field a couple of hundred yards from my home on the Clady Road near Cushendun and when I was walking home my neighbour John McAuley told me he had found a similar pile of feathers in a field behind his house.
I would say that the pigeon which came down in Paddy’s field was taken by a fox: I could tell by the saliva on the feathers and it would seem that the bird in John’s field was also taken by a fox.
Another regular hill walker told me that two miles to the North of Cushendun he had found two peregrine falcons lying dead among dead pigeons in a field close to Cushleake moor where the shooting rights are held by the National Trust. When he went back next day to collect the dead peregrines, they were gone – with fox again the prime suspect.
I first heard about the tragic loss of wood pigeons on New Year’s eve but nobody, except locals, seemed to be interested in the details.
I am long past the stage where I can walk up the steep hill to the flightpath but men who have been there since the start of the year tell me they have seen, not only dead pigeons lying around in profusion, but they have watched as pigeons, coming in to roost or feed on holly berries, could not hold on to the branches and fell to the ground to die a short while later.
They said they had watched as pigeons, coming in on their normal flightpath, just ‘fell out of the sky like flies.’ The man who first told me of the wildlife disaster said some of the dead or dying pigeons had a greenish substance on their beaks.
My granson Daniel said he had seen a wood pigeon staggering about on the road at Coskib near Cushendall in what looked like a drunken state; it was unable to fly away.
When I asked another person – not a shooter – if he would bring in some of the dead birds so that I could send them off for scientific examination, he said with a hint of malevolence:
“I’ll not be touching any dead birds; if the buzzards and falcons pick them up and pay the price I’ll not be shedding any tears. These raptors take a heavy toll of our own wildlife every year and we could do with a rest from them.”
I am indebted to http://www.wildlife –rescue.dot.org.uk and http://www.bto.org for information which might be helpful in determining the cause of the deaths. I have calls out to several other experts but at the time of writing I have not had the information I require.
The sources mentioned above say: “Alternatively known as frounce or canker, this ailment is caused by an organism called Trichomonas gallinae, a mobile single celled protozoan that lives in the sinuses, mouth and throat of birds and which, under certain conditions, can multiply out of control. It has become a well known garden disease after the noticeable effect it has had on greenfinches in recent years.
“Rescue centres tend to see it more in pigeons and doves, as well as the birds of prey that feed on birds, such as sparrowhawks, kestrels and tawny owls. It is most prevalent in warm, damp weather, particularly late summer/early autumn.
“Characteristic lesions in the mouth of a juvenile wood pigeon characterised by yellow/white lesions in the mouth and throat of the bird, a thick, mucoid saliva and swellings around the eyes, the organism will grow until eventually the bird cannot feed properly and dies of starvation or predation. The more advanced the disease is, the more difficult it is to treat.
“Other signs of the disease that would be noticeable to members of the public would be birds that have dirty looking beaks with patches of wet feathers around the beak area and swollen eyes. Any birds that have difficulty swallowing food are fluffed up, lethargic and slow to fly off will also need help. It should be noted that this is a disease of birds only and cannot be passed on to cats, dogs, rabbits or humans.
“It is believed that the increase in the spread of this disease in recent years is due partly to a lack of hygiene around bird feeding and watering stations. A bird with trichmoniasis drinking from a bird bath is likely to pass the disease on to others and so continue the spread of the disease.
“Disinfectants are all very well but the only definitive way to kill trichomonas gallinae is by desiccation, i.e. drying out. Leaving feeders and especially bird baths to dry out after washing them is vital. A recommended drying time is 48 hours or at the very least (when regularly cleaned, i.e. weekly) 24 hours.”
The above sources also mention Chlamydiosis which, they say is most commonly recognised as a disease of pets. They say affected birds may appear to have difficulty breathing and/or have discharge from their mouth, nose or eyes. Affected wild birds may also simply be found dead.
They say: “Chlamydia psittaci bacteria can persist in the environment for months in a resistant form. Transmission can occur through direct contact between infected birds, ingestion of infected secretions (faeces, ocular and respiratory secretions), and/ or inhalation of contaminated dust or aerosols.”

According to the people in Dolakha Bazaar, dead pigeons are lying on the streets, rooftops, gardens and paddy fields. The stench from dead birds pollutes the atmosphere.
“Approximately 5,000 pigeons have died in a week,” said Bharat Shrestha, treasurer of the Bhimeshwor temple prayer and trust management committee.
Authorities are yet to respond to the situation. Vets said an unidentified virus may be responsible for the menace while the locals have got into a panic fearing a disease outbreak in humans.
“Such cases happened in the past but the damage this time is terrible,” said temple caretaker Kashi Narayan Shrestha. He added that rooftops and areas surrounding the temple had yet to be cleared of dead pigeons.
