The Baikal Teal is also known as Formosa Teal or Spectacled Teal or Bimaculate Duck or Squawk Duck. The binomial name is Anas Formosa. Baikal Teals measure between 15"-17" in length and approximately 16" in height. They weigh around 1 lb and enjoy a life span of between 20 and 30 years.

The drake has green, brown, black and white ornamental plumage and has dark-spotted pinkish breast, bluish-grey sides and black tail feathers with shoulder feathers which are long, with streaks of chestnut-red, black and white making it more attractive than the hen. The bill is dark gray to black, legs and feet gray. Hens are not as brightly colored as the drakes. The hens have throats white in color and have a white spot at the base of the bill. Hens are very light at the eyebrow area and are dark at the crown. The juveniles have dark blotches on the whitish underside. The drake emits a deep, chuckling wot-wot-wot sound while the hen emits a low quack.

Baikal Teal Ducks feed on seeds and grain for which the PECk-O-MATIC Automatic Duck Feeder can be used to combat the wastage of feed that can happen with traditional feeding methods. If feeding corn, the inch or 1-inch regulator disc can be used. The 3/8-inch regulator disc from PECk-O-MATIC Automatic Duck Feeder can be used when crumble or milo constitute the feed. Baikal Teal Ducks also feed on water snails, algae, and a variety of water plants.

They nests in fields close to water and eggs are laid by the end of May, the number of eggs being between four and ten. However, Baikal Teal Ducks residing furthest North wait until June. The eggs take 24 to 25 days to hatch. Drakes and non-breeding hens moult shortly after the eggs hatch, but hens, who continue to care for the ducklings, begin their moult later, towards the end of July. The ducklings learn to fly by August, and become independent of the adults.
