Swan Goose Fun Facts
What do swan geese look like?
A swan goose (Anser cygnoides) is a grayish-brown color with a long neck and maroon eyes. Its long black-colored bill is circled with a distinct white stripe that circles the entire area and separates it from the head.
They are overall white but their feathers are dark brown on their backside, underside, and wings. They have orange-colored legs and feet just like any other species from the Anatidae family.
The only difference between male and female swan geese is that males are a bit bigger. Goslings look different because they have a paler plumage and the dark brown streaks on the belly and the white base of the bills are missing.
A domesticated goose, also known as a Chinese goose, has two physical features which are missing in a wild swan goose. One is a broad knob-like structure at its bill base and another one is a white patch behind its black bill.
How cute are they?
Swan geese look very cute when they are seen preening each other to show their love and affection. Apart from that, goslings are also quite adorable.

Swan geese communicate through their loud ascending calls which sound like honking. When the birds belong to the same group, they mostly communicate with each other by wiggling their heads and honking slightly higher than usual.
If they want to warn their group, they make the same honking sound but in repeated intervals. Geese also honk and produce duets with their partners.

Did you know...
Wild swan geese are team players. They coordinate with each other during their harsh migration flights by honking so that the others can maintain pace. The leading goose guides the way and when he gets exhausted, another one takes up the responsibility to guide the flock to their goal.
