A small duck with a chestnut head and a green sheen that only shows in good light. The male chestnut teal wears this outfit. The female is mottled brown. She is unremarkable. She is better camouflaged. She does most of the nesting. She does not need to be flashy. The distinction is clear. The function is practical. The male displays. The female survives. This is the arrangement. It works for them.
The bill is blue-grey. The eye is red. The chestnut body contrasts with dark upperparts and a white patch on the lower belly. In flight, the green speculum flashes white edges. It is a handsome bird. It knows this. It does not seem to care. The appearance is striking. The attitude is indifferent. The bird focuses on feeding. It does not focus on admiration.
It feeds by dabbling. It tips forward in shallow water to reach submerged plants. Seeds, aquatic vegetation, and small invertebrates are the target. It also grazes on grass when the tides are low. It is a duck that eats from both the water and the land. It is flexible. The diet changes with the location. The method remains the same. Tip. Reach. Eat. Repeat. The motion is graceful. It looks effortless. It is not. It requires balance.
Breeding takes it to dense coastal vegetation. The nest is a scrape lined with down. It is hidden under a bush or in a grass tussock. Eight to ten eggs are laid. The female incubates alone. The male stands guard nearby. When the ducklings hatch, they leave the nest within hours. They follow the female to water. She leads. They follow. That is the arrangement. The independence is immediate. The guidance is essential.
The call is a sharp, chattering whistle. It is often heard at dusk. The male sounds different from the female. He is louder. She is more persistent. It is a conversation that outsiders cannot quite follow. The sounds mark the pair. They keep them together. They signal intent. The noise is low. It does not carry far. But it is enough.
The chestnut teal is closely related to the
grey teal. The grey teal is common in New Zealand. They hybridise where their ranges overlap. The offspring are fertile. The species boundaries blur. The ducks do not mind. The genetic mixing is natural. It is not problematic. It reflects proximity. It reflects compatibility.
In Australia, it is a bird of the coastal fringe. It is rarely found far from salt water. In New Zealand, it turns up on freshwater lakes as often as on estuaries. It is a visitor that seems confused about its preferences. It feeds anyway. It survives. It does not stay. The presence is temporary. The location is unintended.
The chestnut teal was once shot as a game bird in New Zealand. A few were released. They did not establish. The birds that arrive now are genuine vagrants. They cross the Tasman on their own wings. It is a long flight for a small duck. They make it anyway. The effort is significant. The reward is uncertain. The bird carries on. It keeps moving. It keeps searching. It keeps surviving. And that seems to be enough.
