Detailed introduction
The Kayssal pintail, scientifically known as Anas eatoni, has two subspecies.
The Kaito Pintail inhabits freshwater lakes, marshes, and streams, migrating to coastal lagoons in winter. It primarily floats on the water's surface, is adept at diving, and forages underwater. Its webbed feet allow it to swim and play in the water, its tail remaining above the surface during swimming. It is skilled at foraging, playing, and courtship in the water. Playing in the water helps maintain feather hygiene and promotes feather growth. Its diet consists mainly of plant seeds and small animals such as crustaceans, shellfish, and worms.
The Kaido pintail duck builds a simple nest using reeds, grass stems, and feathers. The breeding season is from April to June, and each clutch contains five eggs.
Listed in the International Union for Conservation of Nature (IUCN) Red List of Birds, 2009 ver 3.1.
