Pallas Fish Eagle – Distribution, Threats, and Conservation Status

Recently, after a decade, the Pallas fish eagle was observed in Chilika during a bird census.

About Pallas Fish Eagle:

• Scientifically known as Haliaeetus leucoryphus, Pallas’s fish eagle is a large, brownish sea eagle.
• It inhabits a wide range from Kazakhstan to Bhutan, including India, China, and several other Asian countries.

Taxonomy and Evolution:

• First described in 1771, Pallas’s fish eagle’s phylogenetic place among sea eagles remains unclear.
• Retains ancestral traits like dark eyes, bill, and talons.
• Its unique distribution and characteristics indicate a fairly independent evolutionary path.

Behaviour and Ecology:

• Notable for its ability to attack and lift heavy prey, including adult water birds.
• Dominates other raptors in its habitat, occupying high perches and having significant daily food intake.

Distribution and Habitat:

• Spans across various Asian countries, found near freshwater sources.
• Prefers habitats with abundant fish and suitable nesting sites.

Threats:

• Habitat degradation,
• Pollution,
• Human persecution, and
• Disruption of food sources.

Conservation Status:

• IUCN Red List: Endangered
