The Tasman Sea island thrush is an extinct forest bird in the thrush family that was formerly found on Lord Howe Island and Norfolk Island in the Pacific Ocean. It is part of the "island thrush" complex that has been split into 17 species based on a molecular phylogenetic study published in 2023. The two subspecies of the Tasman Sea island thrush became extinct in historical times.
Region
Tasman Sea
Typical Environment
Historically restricted to subtropical evergreen and palm-dominated forests on Lord Howe and Norfolk Islands. It frequented dense understorey, fern gullies, and forest edges, often along stream courses and sheltered slopes. The species foraged primarily on the forest floor but also moved through lower and mid canopy for fruiting trees. As an island endemic, its range was extremely limited and highly sensitive to habitat disturbance.

The Tasman Sea island thrush was an extinct forest-dwelling thrush once confined to Lord Howe Island and Norfolk Island. It belonged to the former island thrush complex that was split into multiple species based on molecular evidence in 2023. Both of its subspecies disappeared in historical times, largely due to introduced predators and habitat loss. Accounts describe it as notably tame, often foraging on the ground in leaf litter.
Extinct subspecies from Lord Howe Island
Temperament
tame yet shy when disturbed
Flight Pattern
short rapid wingbeats with low, direct dashes between perches
Social Behavior
Typically encountered singly, in pairs, or small family groups. Territorial during breeding, with cup nests placed in shrubs or small trees. Clutches were small, and both parents likely contributed to feeding and defense of the young.
Migratory Pattern
Resident
Song Description
A rich, melodious thrush-like song composed of fluted whistles and mellow phrases delivered from low perches. Calls included soft chucks and thin tseep notes, especially when alarmed.
