The Norfolk triller (Lalage leucopyga leucopyga) was a small passerine bird in the cuckooshrike family, Campephagidae. It is the extinct nominate subspecies of the long-tailed triller which was endemic to Norfolk Island, an Australian territory in the Tasman Sea between Australia and New Zealand. Little is known of its biology.
Description
[edit]
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
[edit]Breeding
[edit]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
[edit]Despite being recorded as 'abundant' in 1941,[2] 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][3]
