Since time immemorial, angulu has been one of the most ubiquitous birds in India.
The birds are found in fields and farms, where they roam in search of food.
Sometimes they get stuck on airplane engines while taking off.
However, more than ten years ago, the angler birds began to die due to a drug that is used to treat cattle.
In the mid-1990s, the 50 million angler birds were almost extinct because of this treatment of cattle.
Birds that ate from dead animals that had been treated with the drug developed kidney problems and died.
Since diclofenac was banned in 2006, the protection of the eagle has declined in some areas, but at least three species have experienced losses ranging from 91-98 percent, according to a report on birds in India. recently.
Moreover, a study published in a magazine in the United States found that efforts to reduce the number of birds, caused the death of about 500,000 people in five years.
“Angles are considered cleaner because of the role they play in removing dead animals that carry bacteria from our environment – without them, diseases would spread,” said Eyal Frank, assistant professor at the University of in Chicago.
“Recognizing the role of the angler in human health, that is why it is important to protect wild animals. They are important in our lives.”
Mr. Frank and his co-author Anant Sudarshan compared the number of deaths in some provinces of India that were once home to vultures and their decline.
They found that some medicines that are sold wrongly, have caused an increase in the decline of the angulu family, where the number of deaths has increased by 4 percent in the provinces where the birds used to live.
The researchers also found that the effects were more visible in urban areas where there were more abandoned animals.
The researchers estimated that between 2000 and 2005, the loss of egrets caused an additional 100,000 deaths each year.
The deaths were caused by the spread of diseases and bacteria that, if the eels were present, they would have removed them from the environment.
For example, if there are no birds of prey, the family of dogs increases, which also brings diseases in people.
There was an increase in sales of anti-inflammatory drugs at that time, but they were not enough.
Unlike ungulates, dogs are not able to remove the remains of dead animals in the environment, which leads to the spread of bacteria into drinking water.
Among the vulture family in India, the white vulture, the Indian vulture and the red-headed vulture are among those that have experienced a long-term decline since the early 2000s, with their numbers dropping to 98, 95 and 91 percent, respectively.
The number of people in Egypt and the number of people who migrated has also decreased significantly.
The 2019 livestock census in India counted more than 500 million animals, which is the largest number in the world. History shows that farmers depended on anguls, which usually feed on dead animals, to remove the remains of dead animals from their farms.
The decline of the angler in India is the fastest-growing population of any bird family and the largest since the endangered pigeon in the United States, according to researchers.
The remaining ungulates in India are now in protected areas, where their diet mostly consists of dead animals, according to a report on birds in India.
This improvement in angle reduction has also had a negative impact on human health.
Experts have warned that veterinary drugs are still a threat to the angler, the abundance of dead animal parts and the lack of disposal of the animal carcasses is exacerbating the problem.
They also said that mining can also affect the social status of the angulu family.
Will there be a comeback? It can be said that this is very difficult, although there are good signs for this. Last year, 20 angler birds were released from a tiger reserve in West Bengal.
More than 300 angler birds were captured in a recent survey in southern India. However, there is a need to increase efforts to protect them.
