Bar-headed Goose
Anser indicus
The bird is pale grey and is easily distinguished from any of the other grey geese of the genus Anser by the black bars on its otherwise white head. It is also much paler than the other geese in this genus. In flight, its call is a typical goose honking. A mid-sized goose, it measures 71–76 cm (28–30 in) in total length and weighs 1.87–3.2 kg (4.1–7.1 lb).

Lesser White-fronted Goose
Anser erythropus
The two white-fronted goose species differ little other than in size (the lesser, at 53–66 cm (21–26 in) length and with a 120–135 cm (47–53 in) wingspan, is not much bigger than a mallard (Anas platyrhynchos)), but both may be readily distinguished from the greylag goose by their bright orange legs and their mouse-coloured upper wing-coverts. The greylag goose has a flesh-coloured bill and legs and the upper wing-coverts are bluish-grey. Both white-fronted goose species have a very conspicuous white face and broad black bars which cross the belly.
