The endangered fishing eagle marked in Mongolia continues to fly to the same place in the Kaziranga National Park in Assam and Tiger Reserve for the reproduction season since 2020.
Pallas’s Fish Eagle (Haliaeeetes Leucoryphus) is considered to be a poorly studied large bird of its kind over the flying range along the Central Asian Flyway (CAF), one of the nine global migration routes of waterfowl.
The male Raptor marked by a Mongolian scientist in Ulaanbatar based in nature and nature protection gave ornithologists in India a view of how he lives between two countries, about 3,000 km apart by air.
Scientists of Bombay Natural History Society (BNHS) recorded a bird named Ider, 16 March this year.
“We found the Ider in the hope of finding two Young Pallas’s Fish Eagles, which I marked in 2013. We found that this bird was marked by D. Batmunkh of Mongolia,” said Sachin of the BNHS Rule on Monday (April 7, 2025).

Communication with Mongolian scientist revealed that Ider used various flight paths along the CAF to consistently achieve the same destination-buuuksagaan lake in Central Western Mongolia during the period without breeding from June to September and water units at the core of 1,302-SQ. KM Kaziranga behaves from November to March.
“We watched two chickens in the marked bird’s nest. Although we cannot say how many chickens that set fire to the conclusion that it behaves in Kaziranga every year for five consecutive years,” Dudes.
Ider used the same nesting place four times and moved the location only in the main area of Kaziranga.
Sonali Ghosh, the field director of Kaziranga, said Pallas Fish Eagle showed the behavior of “interesting reverse migration” because he behaves in a rhino domain rich in wetlands and flies to Mongolia every year. “Kaziranga is one of the best places on the ground that observes this bird, one of the largest fishing eagles,” she said.

Flying
Like many large birds, it is known that the Pallas fish eagle is paired throughout life (monogamous), but usually migrate individually after breeding.
“As soon as they behave, they don’t have to stay together. They create a couple again when it is time to breed and produce an average of two chickens a year,” Dr. Dudes.
The chickens become independent in two months, fish and hunt other birds and mammals and fly to Mongolia. “They do not need parental guidance, fly through instinct to walk through the café,” he said.
According to Birdlife International, the Pallas’s Fish Eagle series has significantly inserted; In its former fortress, such as Caspian and Kazakhstan, this is largely missing. It is estimated that there are 2,500 mature individuals in the wild.
The main minister of Hisant Biswa Sarma noted annual trips to Kaziranga as “Assam on the map of epic birds”.

Three fly
India is located in the center of CAF, including migration routes from Siberia to West and South Asia. Flyway covering at least 279 populations of 182 waterfall species is 30 countries of North, Central and South Asia, except for trans-kaukas.
India organizes about 370 migration species of birds from the three main flights-caf, East-Asian Australlasian Flyway (EAAF) and Asian East African Flyway-S 310 species mainly using wetland stations covering 15.26 million hectares.
Kaziranga, a UNESCO World Heritage Site, and other wetlands in Northeast India serves as a winter bird area using CAF and EAAF.
While many telemetry studies on racants investigating their movement and migration formulas have been performed worldwide, less than 1% of the total bird species found in India were studied using satellite telemetry.
More known for their large five-principle rhinos, tiger, elephant, wild water buffalo and swamp-gauge is also home to more than 500 bird species, as more than 50% of its mainland is connected to Beely (water formations) under grassland.
The sixth survey of Kaziranga Waterbird brought 124 species of birds addicted to water and wetland, a total of 112,062 individuals from 25 families to 189 Beels. Especially 62 species were winter migrants, among them Pallas Fish Eagle.
