Grey shrikethrush

The grey shrikethrush or grey shrike-thrush (Colluricincla harmonica), formerly commonly known as grey thrush, is a songbird of Australasia. It is moderately common to common in most parts of Australia, but absent from the driest of the inland deserts. It is also found in New Guinea.

Taxonomy and systematics

The grey shrikethrush was originally described in the genus Turdus. Alternate names include the brown shrike-thrush, buff-bellied shrike-thrush, grey shrike-flycatcher, northern shrike-thrush and south-western shrike-thrush.

Subspecies

Five subspecies are recognized:[2]

  • C. h. brunnea - Gould, 1841: Originally described as a separate species. Found in northern Australia and Melville Island
  • C. h. superciliosa - Masters, 1876: Originally described as a separate species. Found in eastern New Guinea, islands in the Torres Strait and north-eastern Australia
  • C. h. harmonica - (Latham, 1801): Found in eastern Australia
  • C. h. strigata - Swainson, 1838: Originally described as a separate species. Found in Tasmania and the islands in the Bass Strait (Australia)
  • Western shrikethrush (C. h. rufiventris) - Gould, 1841: Originally described as a separate species. Found in western, southern and central Australia

Description

Of medium size (about 24 cm or 9.4 in long) and lacking bright colours, the grey shrikethrush—usually just thrush in casual conversation—has an extraordinary gift for ringing melody, unmatched by any other Australasian species save perhaps the two lyrebirds and its northern relative, the sandstone shrikethrush.

Status

The grey shrikethrush is evaluated as least concern on the IUCN Red List of Threatened Species.

  • In Victoria
  • In Tasmania
  • Juvenile
  • Dorrigo, NSW, Australia
gollark: And brains are annoying to do things with since they're not understood very well and can't be copied/run in simulation very easily.
gollark: Running neural nets in analog hardware would also be kind of disadvantageous, since you couldn't then copy them very easily or run them on new stuff.
gollark: I'm sure there are lots of widely used ones which are.
gollark: What do you mean you're looking for a white color?
gollark: Maybe you should find a better geological engineering course somehow.
