The striated caracara (Phalcoboenus australis) is a bird of prey species of the Falconidae family. This bird is also called a Johnny rook on the Falklands, perhaps named after the Johnny penguin (gentoo penguin). This species is almost black with silver, orange, chestnut, gray, and brown adult plumage.

This species is Near Threatened, with only a few breeding pairs left in the world. The Phalcoboenus genus is a small group of caracaras. The four extant species of this genus are allopatric.

There is one extinct bird in this genus. They are opportunistic feeders and can often be found on the ground, feeding on carrions.

The young ones have completely brown plumage. This species is found on the Falklands, the Andes, Tierra del Fuego, and Patagonia. They occupy open and barren habitats.

In the Falconidae family, there are 60 caracara and falcon species. Willian Elford Leach, an English zoologist, introduced Falconidae in 1820 in the British Museum's guide to contents. There are three recognized subfamilies in this family, Falconinae, Polyborinae, and Herpetotherinae.

This caracara scratches for insects in tidal areas and also turns stones in search of food when seabirds are absent from breeding colonies. This caracara is not known to kill healthy young animals.

This bird has a bad relationship with sheep farmers because this raptor is attracted to dead sheep or weak or stranded animals. The striated caracara also digs up burrows using its strong legs and claws in search of small seabirds.

This bird is usually attracted to red objects and there have been records of this raptor stealing red objects around the islands. This bird also attacks intruders entering their territory even if that is a human.

The striated caracara (Phalcoboenus australis) belongs to the class of Aves of Animalia.

How many striated caracaras are there in the world?

The population number of striated caracara (Phalcoboenus australis) birds in the world is estimated to be 1,000-2,499 mature birds, which means there are 1,500-3,000 adults. A survey in 2006 showed that the breeding population distribution is stable with 500 breeding pairs.

Where does a striated caracara live?

This caracara occupies islets of extreme South America, occupying the countries of Chile and Argentina, and the islands of Cape Horn, Navarino, and Staten. These birds are also found on the Falklands.

The striated caracara (Phalcoboenus australis) or Johnny rook is found in the southeast range of coastal islands off Tierra del Fuego, extending to the outer islands of the Falklands archipelago and the Chilean fjords.

The Falklands is believed to be where the stronghold of the population of this bird is. Records from history suggest that the population might have occupied East Falkland.

What is a striated caracara's habitat?

The habitat of the striated caracara (Phalcoboenus australis) population includes coastal islands, open lowlands, and rocky coasts. The range in rocky coasts extends from tidal zones perhaps to coastal mountains at higher altitudes. This species can only be found among seabirds and seals in islands.

Who do striated caracaras live with?

Striated caracaras form flocks and wander across islands. They are quite social.

How long does a striated caracara live?

Striated caracaras live for around 10 years.

How do they reproduce?

These birds breed on islands off Tierra del Fuego, South America. The breeding season of these birds is in austral summer, from December to late February.

Striated caracaras build their nests under a tussock of grass or on rock ledges. They build their nest using dried grass and twigs and if available, they line it with wool. They build their nest in loose colonies, and the neighboring breeding pairs are invisible from each nest.

Both adults perform displays in the breeding season, particularly head throwing displays. If the nest sites are limited, they build it at less than 0.006 miles (10 m) apart.

Striated caracara female birds lay four eggs. Juveniles hatch when the seabirds start to nest and this provides a constant food source for the chicks. Both adults defend their nests by chasing away intruders. After fledging the nest, juveniles form flocks and wander across islands. They can fearlessly attack campsites.

What is their conservation status?

The conservation status of striated caracaras is evaluated as Near Threatened by BirdLife International. The distribution in the Falkland has faced heavy persecution. The population of these birds has also had conflicts with sheep farmers, which has now been corrected in the Falkland Islands to conserve this wildlife species.
