Snow Goose

The migratory bird is known for its snow-like color that gets it’s the name. There are usually two color morphs of the species and the birds belonging to different morphs often crossbreed with each other. The otherwise carnivorous bird sometimes consumes larvae of flies during its initial days post-hatching.

Behavior

  • While migrating to the south for the winter season, the entire flock makes a shape of v in the sky.
  • Their roosting time is during the night being afloat.
  • They have the capacity to sleep while swimming.

Mating and Reproduction

Post winter, snow geese return to the north and adult ones look for mates. They try to find their counterparts similar to their parents’ coloration, although this is not the case always. Nesting is typically observed at the end of May. Females lay 2-6 eggs followed by an incubation period of 22-25 days.

Life-cycle

Hatchlings are usually covered with down and their eyes are open. They become able to eat and swim without any help within 24 hours of birth and after 42-50 days, they start flying. Despite their ability, they are supervised and kept under the protection of their parents for another 2-3 years.
