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).

Swan Goose
Anser cygnoides
The swan goose is large and long-necked for its genus, wild birds being 81–94 cm (32–37 in) long (the longest Anser goose) and weighing 2.8–3.5 kg (6.2–7.7 lb) or more (the second-heaviest Anser, after the greylag goose A. anser). The sexes are similar, although the male is larger, with a proportionally longer bill and neck; in fact, the largest females are barely as large as the smallest males. Typical measurements of the wing are 45–46 cm (18–18 in) in males, 37.5–44 cm (14.8–17.3 in) in females; the bill is about 8.7–9.8 cm (3.4–3.9 in) long in males and 7.5–8.5 cm (3.0–3.3 in) in females.
