Although the Chiloe wigeon is a common species, especially in parts of Chile, hunting pressure and loss of habitat have affected their numbers.
They breed well in captivity and can be seen in a large number of zoological parks and gardens.
Chiloe wigeons are highly social birds especially during the non-breeding season. They feed mainly on dry land but can be seen dabbling and upending
while in open water. The short bill of the wigeon makes it easier to graze on grasses. Migration is limited for the wigeon and is determined by
food and water supplies.
Reproduction and Breeding
Breeding season begins with mutual displays of chin-lifting movements and vocalizations. Both the male and female frequently display preening behaviors and the male will regularly turn his head as he swims ahead of
his mate. Even in flocks of 100, strong pair bonds can form during this time. Chiloe wigeons have the strongest pair bonds of all wigeons. The female will seek out a nesting site in tall grasses or weeds. The male does not assist in incubation but remains nearby protecting the nest. He will rejoin his mate after the ducklings hatch and attend to the young.
This portrait was taken at WWT Slimbridge, not Chile!! But as people occasionally post butterflies from hot-houses, I thought this would be OK.
Cropped, resized and sharpened in CS3.
