Description
The Norfolk Island 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.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.Extinction
The Triller was last recorded in 1942. The cause of its extinction was probably predation by Black RatBlack Rat
