Breeding
On the Falkland Islands the striated caracara breeds between late October and January. Its nest is built of twigs and grass on the ground, under tussoc grass clumps, or on cliff ledges. It usually nests in loose colonies with nests sometimes as little as 7 m (20 ft) apart, and there is some evidence of cooperative breeding. The clutch size is usually two eggs but can be up to four. The incubation period, time to fledging, and details of parental care are not known.[4][16]
