Canary

The canary is a small bird only mentioned in the How to Train Your Dragon franchise.

Description
There are two species of canary: the Wild Canary (Serinus canaria), also known as the Atlantic Canary, and the Domestic Canary (Serinus canaria forma domestica). They are both in the genus Serinus of the family Fringillidae.

The main color of a canary is yellow. However, the domestic species were also bred red, white and orange. They feed mostly on seeds, but the wild canaries also eat small insects. The males have a beautiful silvery twittering song, both wild and domesticated.

Function
There is no specified function for the canaries, although they might be kept as pets like in the real life.
