Description

Illustration by Georg Forster from the 1770s

The Norfolk triller was similar to other subspecies of the long-tailed triller, though it was slightly larger and had a richer buff wash on the underparts and rump and a broader white tip to the outer rectrices.[1]

Behaviour

Breeding

Breeding was recorded in September, with eggs in December and February. Nests were shallow and cup-shaped, made of lichen, moss and fibrous roots, and lined with finer material. The clutch was usually two eggs.[1]

Extinction

The triller was last recorded in 1942. The cause of its extinction was probably predation by black rats combined with clearance of its habitat, Norfolk Island's native subtropical rainforest.[1]

There are specimens of this bird held in the museums at Leiden, Vienna, Tring and in the H. L. White Collection at Melbourne.[1][2]
