The black-throated whipbird (Psophodes nigrogularis) is a passerine bird found in several scattered populations in Southwest Australia. It is predominantly olive green in colour. It was formerly considered to be conspecific with the white-bellied whipbird (Psophodes leucogaster), so shares the common name "western whipbird".

Taxonomy

The black-throated whipbird was described by the English ornithologist John Gould in 1844 and given its current binomial name Psophodes nigrogularis.[2]

Two subspecies are recognised.[3] Both are under threat to some degree.

  • Psophodes nigrogularis nigrogularis: (Endangered) The Western heath subspecies is now restricted to a small patch east of Albany, having disappeared from large parts of its range due to land clearance.[4]
  • P. n. oberon: (Rare) The Western mallee subspecies is found in scattered populations between the Stirling Ranges and Ravensthorpe. It is apparently common in the Fitzgerald River National Park.[5]

The white-bellied whipbird (Psophodes leucogaster) was formerly treated as conspecific with the black-throated whipbird. It was promoted to species status based on an analysis of mitochondrial DNA sequences published in 2017.[6] The Clements Checklist refers to this species with the common name western whipbird (black-throated) to distinguish it from P. leucogaster (white-bellied).[7]

Description

The black-throated whipbird is slim bird some 21–25 cm (8.3–9.8 in) in length. It it is olive green with a black throat and a narrow white cheek-patch edged with black on its face. It has a small crest and a long dark olive-green tail tipped with white, its underparts are a paler olive colour. The bill is black with blackish feet. Juveniles are a duller olive-brown in colour and lack the white cheek stripes and dark throat.[8]

Breeding occurs in spring; a bowl of twigs and sticks lined with softer material such as grasses, located in shrubs or trees less than 1–2 m (3 ft 3 in–6 ft 7 in) above the ground. A clutch of two eggs, pale blue with blackish splotches and spots, measuring 26 mm × 19 mm (1.02 in × 0.75 in).[9]
