Similar species in India: None. It is a very distinct (morphologically) species and cannot be confused any other species that occurs in India.

Sexual, seasonal & individual variation:

No distinguishable sexual dimorphism exists except for males being slightly larger than females. Also, no discernible individual variation exists. However, with a closer and careful inspection of bars on the head especially relative lengths, angle with neck and relative position with eye may provide a preliminary individual distinction.
Status, Habitat and Habits:

It is a gregarious species, forming family parties of 5 or 6 and flock of 100 or more. It is crepuscular and nocturnal, mainly foraging in the night, however, can be seen active during daytime.

Foraging Behaviour: Extensively herbivorous diet that consists of grasses, roots, stems and green parts of plants berries, insects and small crustacea. It is known to cause serious damage to winter crops in many regions (pers. obs.)

Slow honking sounds but more nasal and musical

Migration Status: Migratory, wintering (November to March) at much lower elevations throughout India preferring
 lowland swamps, lakes and rivers. It is often seen along with Greylag Goose.
