South Georgia Pintail
Anas georgica georgica · also called South Georgia teal
Scavenging seal carcasses and seabird eggs alongside its more typical diet of plants and invertebrates, a South Georgia pintail survives on a single remote sub-Antarctic island group, one of the very few duck species adapted to conditions this harsh.
Overview
The South Georgia pintail, Anas georgica georgica, is a cold-adapted duck native to coastal and polar habitat on a specific sub-Antarctic island group. Its unusual carrion-scavenging diet, extreme cold tolerance for a duck, and highly restricted island range make it one of the more ecologically unusual waterfowl found anywhere in the Southern Hemisphere.
A duck that learned to scavenge
Far from the plant-eating, insect-hunting habits typical of most ducks, the South Georgia pintail has adapted to its isolated, resource-scarce island home by scavenging carrion whenever it can find it, a survival strategy shaped entirely by its remote sub-Antarctic evolutionary history.
Status
Least Concern, remaining stable across its limited island range, though the entire subspecies depends on the continued health of this one restricted habitat.
South Georgia Pintail: common questions
Why is the South Georgia pintail unusual among ducks?
This subspecies regularly scavenges seal carcasses and seabird eggs, a carrion-eating habit unusual among ducks, which typically rely instead on plant material and small invertebrates for food.
Where is the South Georgia pintail found?
This subspecies is found only on a specific sub-Antarctic island group, making its entire population dependent on the continued health of this one limited range.
How does the South Georgia pintail survive such cold conditions?
This subspecies tolerates conditions considerably harsher than most other duck species are adapted to, reflecting its isolated sub-Antarctic evolutionary history on one remote island group.
What does the South Georgia pintail look like?
This subspecies has relatively drab, mottled brown plumage, providing effective camouflage against the tussock grass and rocky terrain of its sub-Antarctic island habitat.
