Synonyms: Cracticus argenteus

Wikipedia Abstract

The silver-backed butcherbird (Cracticus argenteus) is a small, shrike-like bird. It is almost identical to the grey butcherbird (C. torquatus) of which it considered by some authorities to be a subspecies, C. torquatus argenteus. The species was first described by ornithologist John Gould in 1836 as Cracticus argenteus.
