Eaton's Pintail (Anas eatoni)
Eaton's pintail (Anas eatoni) is a duck of the genus Anas.
It is also known as the southern pintail. This species is unique to the islands of Kerguelen and Crozet in the southern Indian Ocean. It looks like a female pintail. He is named after the English explorer and naturalist Alfred Edmund Eaton. It is threatened by introduced species, especially feral cats, which feed on it. There are two subspecies: A. Eatoni Eatoni (Kerguelen Pintail) and A. eatoni drygalskii (Crozet pintail). Description of this species:

Biometrics:
Height: 35-45cm
Height: 65-70 cm
Weight: M: 430-500 g - F: 400-500 g
Eaton's Pintail is generally brown overall. The upper part is usually red-brown and the same fit. In the wings, the pattern is green. In the tail, the middle rectrices are slightly elongated, but not as much as in the Northern Pintail. The outer rectrices are white.
Some males (about 1%) have a brown head with white stripes on the sides, making them look like Anas acuta. The bill is blue-grey with a prominent black tip. Eyes are dark brown. The webbed feet and legs are grey.
In eclipse plumage (May to November), it looks like a female. The adult female is smaller and darker than the Anas acuta female. It has a brown speculum (not green), with a white tip. The young one looks like a woman but has a longer lower part. A boy who grows up quickly acquires bright details. WORDS AND TIMES:
Eaton's Pintail has two regions.
A.e. eatoni in the Kerguelen Islands. It used to be introduced to Saint Paul Island and Amsterdam Island, but the species has disappeared from these islands.
A.e. drygalskii is found on Crozet Island. This race is similar to the selection, but the lower parts show a narrow trunk, which has wings and has small wings.
Residence:
Eaton's Pintail feed mostly in coastal areas and sheltered bays during the winter. It frequents lakes, ponds, swamps and streams. He avoids human habitation in general. WORDS AND SONGS:
Eaton's Northern Pintail has a higher pitched voice than Anas acuta. It is usually quieter, including young people. NATURAL KNOWLEDGE:
Eaton's Northern Pintail is very aggressive and can be seen with small feeders outside of breeding season. It feeds mainly on crustaceans and invertebrates on the ground. Fruits and herbs are also part of his diet. It usually eats during the day, but during the breeding season, it also eats at night to avoid predation. Eaton's Pintail is generally more terrestrial than Anas acuta. He walks and runs on the ground and flies over rocks and stones. Sexual behavior is unknown, but pairs may be observed during the austral spring. The appearance may be similar to that of other Anatidae. They nest in two separate ways. Their main predator is the Brown Skua. The Eaton's Pintail is relatively sedentary, with some movement to river areas during the winter. It is reported as a visitor to the Prince Edward Islands. This species flies well and travels easily throughout the island.
Release this version:
The breeding season takes place between November and March on the island of Kerguelen. Eaton's Pintail nests in pairs, with nests sometimes 500 meters apart. The nest is on the ground, usually hidden in clumps or among grass. Full of depression and anxiety on the ground. The nest can sometimes be placed in a rock cavity. The female lays 2 to 6 olive-green eggs and lays alone. The time of entry is not known, but it is 22-24 days in Anas acuta, we can say that it is the same or about the same for the current species. Chicks are smaller than those of Anas acuta. They are surface crawlers with red spots on their backs and brown spots on their front, breast and underparts. They are reared only by the female and, like Anas acuta, they can leave the nest 40-45 days after they die.
Security / Threats / Features:
Eaton's Northern Pintail are typically hunted by 200-300 seal hunters on scientific expeditions each year. It is now threatened by introduced predators, especially brown cats and brown rats, while predators are mostly skuas.
The population in the early 1980s was estimated to be 31,200/41,400 eligible people, with 600/700 in Crozet and 15,000/20,000 in Kerguelen. These numbers are still decreasing.
