Description General Info
Description
The adults' plumage is almost black in color, while the legs and lores are orange and the neck has silver striations. Chicks have chestnut down, which they lose after their first molt. Juveniles (i.e., after fledging until entering fourth year) have brown plumage with chestnut striations on nape and breast that deepen as they age. Full adult plumage is acquired after the fifth molt (i.e., entering fourth year), though the beak does not reach full adult coloration until the fifth year.

Dite type
Carnivorous
General Info
Distribution Area
The species breeds on coastal islands off Tierra del Fuego, through the Chilean fjords, and the outer islands of the Falklands archipelago. Although logistical challenges prohibit a comprehensive survey of the mainland population, the Falklands is thought to be the species stronghold. Historical records indicate the species range may have included East Falkland, however striated caracaras now breed only in the outer islands in association with penguin and albatross colonies.
Species Status
The population in the Falklands is estimated at 500 breeding pairs. Juveniles and adults are almost entirely fearless of humans and treat their approach with indifference. Over time, conflict with the sheep farmers has led to a great reduction in their numbers. This is now being corrected by the Falkland Islanders.
