Brown Teal vs Hawaiian Duck

Brown Teal

Anas chlorotis

Large499 gWetland

There are no distinctive differences between a male, female and a juvenile brown teal during non-mating season. They all have a white ring around their eyes as well as a mottled brown colour on their heads and throat. During breeding season the male will begin to change colour, now having a green coloured head, chestnut coloured breast and a white stripe on each side of their body. They will sometimes also have a white clerical neck band. This does vary as some males do tend to be more colourful than others.

Hawaiian Duck

Anas wyvilliana

Large843 gRiverine

Both male and female are mottled brown in color and resemble a female mallard. The males are usually bigger than the females. The speculum feathers of both sexes are green to blue, bordered on both sides by white. The tail is dark overall, unlike the black-and-white tail of a mallard. The feet and legs are orange to yellow-orange. The bill is olive green in the male and dull orange with dark markings in the female. The adult male has a darker head and neck. The female is generally lighter-colored than the male and has plain back feathers. Voice: The Hawaiian duck quacks like a mallard, but its call is softer and it quacks less frequently.
