In particular, he was making a living by doing 'wedding photography'. However, less than a year after starting the studio, interest suddenly changed. Like a river changing its course. It was about 8 years ago, of Deven Kharel of Mechinagar-6, Kakadvitta, Jhapa.

"My inner interest was to do something different from photography," Kharel said. He also showed considerable work in bird research. 

On December 6, 2078, he reached Suryodaya Municipality-1 Simdhap of Ilam and was walking in the nearby forest area in search of birds. Suddenly saw a pair of Rufs-Necked Hornbills. At first he was startled, then he clicked with care and haste. The reason why he was scared and shocked when he saw the crane was that the crane was an extinct bird from Nepal. "I didn't imagine that the missing Hangrayo would be found," Kharel said at that moment, "Hangrayo's picture brought a new turn in my life." 

According to botanist Kamal Maden, in a material released by the International Union for Conservation of Nature (IUCN) in 2020, it is mentioned that the "roofs-necked hornbill" has become extinct in Nepal. According to which this bird is found only in Bhutan, Northeast India, Myanmar, Southeast Tibet, China, Thailand, Laos and Vietnam. "IUCN has listed this bird as endangered since 1994," says Maden, "Finding a bird that is considered extinct in Nepal is a great achievement for Kharelji and a challenge for researchers." 

Since bird researcher Brian Hudson found it in 1829, no one has been able to confirm its existence in Nepal. Experts claimed, 'This bird has become extinct in Nepal.' However, almost two hundred years later, when photographer Kharel found the Hunrayo, waves were created at the international level. The Nepali proverb 'A snake swallows a wheel' is famous in the eastern hills. Therefore, botanist Maden claimed that Hungary could be found in the east. "Remembering this proverb, I found it by chance while roaming the forest," said Kharel.

On November 14, 2077, when Kharel found a bird of the 'Green Pigeon' species, there was a wave across the country. A green pigeon with the scientific name 'Ducula ania' and English name 'Green Imperial Pigeon' was found in the Satighatta area of ​​Mechinagar Municipality-7. The credit of finding this pigeon for the first time in Nepal goes to Kharel's Polta. After taking a photo and sending it to the Bird Conservation Society and ornithologist Hemsagar Baral, it was confirmed that it was a green pigeon. Shortly after discovering the green pigeon, he took a rare photo of a peregrine falcon. The kingfisher is the fastest flying bird in the world. Experts claim that it has the ability to fly up to 320 kilometers per hour. 

During the search for birds, Kharel went up to Sandakpur, a Himalayan region of Elam, about four months ago. He claimed that a wild rabbit named 'Forest Pika' was found there for the first time in Nepal. He found a broken rabbit in Sandakpur in North Elam bordering India. 

Nepal is on the 22nd place in the list of countries where many birds are found. About 887 species of birds are found in Nepal. Kharel has taken pictures of about 400 birds of different species since he started following birds for about 7 years. "In which 382 species of birds have been found in Mechinagar area alone," he said, "Mechi municipality is probably the most bird-friendly municipality in Nepal." He claims that it will take. He said that if the city can be protected by declaring the bird hunting prohibition zone, it can earn foreign currency by bringing in foreign tourists. He says that strange birds can be seen around Mechi and Ninda rivers in Mechinagar, community forests, wetlands and Chure forest on the border with Ilam. 

A bar-headed goose flying above the highest peak Everest was spotted in the Mechi River on February 18. According to Kharel, it is a strange thing to see lost ducks in the Mechi river. Sandeep Luintel, a local conservationist, found 20 hoya ducks strolling in the Mechi River. According to bird conservationists, Khoya ducks travel from Mongolia, China and Central Asia through Nepal to India and return again. It is a long-distance bird. "This is the first time that it has been seen in Mechi," Kharel said, "The sighting of the Khoya duck also confirms that Mechinagar is a paradise for birds."
