Austral Thrush (Turdus falcklandii)

The Austral Thrushes (Turdus falcklandii) – also known as Falkland Thrushes or Magellan Thrushes (subspecies) – are medium sized thrushes that occur naturally in South America.

They are the most southerly-ranging thrush species.

Distribution / Habitat

The Austral Thrushes occur naturally in southern South America, in central and southern Chile, southern Argentina, and on the Falkland Islands.

One single vagrant has been reported from the South Sandwich Islands in the southern Atlantic Ocean.

They occur in various habitats that include Nothofagus forests, open woodland, forest edges, areas with tussac grasses near beaches, agricultural lands and urban backyards and parks.

They are common across most of their natural range.

Diet / Feeding

These thrushes feed on earthworms, snails and insect larvae and other invertebrate. These ground feeders are commonly seen foraging on open lawns and pastures. They will also find their prey among seaweed cast up on the shore. They also eat various fruits, berries and seeds.

Breeding / Nesting

The breeding seasons vary by location:

  • Chile: September to February
  • Argentina: October to November
  • Falkland Islands: August to December

Their large, deep cup nests are constructed out of grasses and roots. On the outside these birds use mud or dung for camouflage and potentially to strengthen the structure. The inside is lined with soft grasses, down or hair.

These nests are typically placed in a concealed location; in dense foliage or in rock crevices.

A clutch consists of two or three eggs, which are incubated for about 14 to 16 days. The young fledge (leave the nest) when they are about 16 to 18 days old,.

Breeding pairs may raise up to three or even four broods in a season, if the conditions for raising chicks are optimal.

Calls / Vocalizations / Sounds

Their songs are described as a “rich series of ‘carolling’ phrases” or “plaintive, slow series of whistles and harsh chuckles.” Their calls include a low ‘huit’ and a harsh ‘wreet
