It is also not unheard of for geese to mate with swans, with the offspring of a swan and a goose known as a swoose. Homosexual behaviour is extremely common across the animal kingdom, from insects to mammals. But only some animals seem to be lifelong homosexuals mating for life.

Gander

With their long necks and legs, geese look like large ducks and are found in many of the same wetland habitats and backyard ponds. Their plumage comes in a variety of colors and, instead of quacking, they make a nasal honking sound.

Blue Ross’s Goose is exceedingly rare. And the morphology of this bird’s head and bill suggest that it might be a hybrid or backcross involving a blue Lesser Snow Goose.

The snow goose (Anser caerulescens) is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage….

The difference between swan and goose is that swans tend to be larger in body length, wingspan, and weight than geese in most cases. Although smaller in size than a swan, a goose typically, has longer legs than the latter.

Swans have all white wings with long, slender necks, while a snow goose has black primary feathers and a short neck. When you take a close look, each swan is different than the other, and although people say snow geese look just like swans, they really are quite different.

All swans are the property of the Queen, and killing one is an act of treason. Not quite Since the 12th century, the Crown has held the right to ownership over all wild, unmarked mute swans in open water. Killing one of the Queen’s mute swans may be unlawful, but it has never been an act of treason.

Killing them without permission could incur an unlimited fine, six months imprisonment or both.

Wild unmarked mute swans belong to the Crown. As such this means that taking or killing a swan could amount to theft and injuring them could amount to criminal damage (both these offences committed against swans have been successfully prosecuted in recent years). If you see an injured swan then contact the RSPCA.
