Song edit

Each individual within the territorial group contributes to the boisterous and exuberant song, which combines harsh and melodic elements. Although a single person can sing the song, groups or duets are more common ways to perform it. Certain duets are antiphonal, meaning that it is difficult to tell that more than one bird is singing. The majority of songs are sung antiphonally and in multiple phases. In these songs, various group members sing various phases one after the other, though occasionally there is overlap. There are songs that can go up to fifteen minutes long. There is no vocal communication with groups from other territories during this period. [7].

Taxonomy edit

The English ornithologist John Latham originally identified the grey butcherbird in 1801 under the binomial name Lanius torquatus. [5].

The black-backed butcherbird (Cracticus mentalis) and the silver-backed butcherbird (Cracticus argenteus) are closely related species. After being first identified by John Gould in 1841, the silver-backed butcherbird (Cracticus argenteus), which ranges from Arnhem Land and northwest Australia to Port Hedland, was eventually determined to be a subspecies of the grey butcherbird. But it has recently been reclassified as a distinct species once more. The silver-backed butcherbird has two subspecies C. argenteus argenteus and C. a. colletti. There are two subspecies of the black-backed butcherbird, which can be found in Papua New Guinea and the Cape York Peninsula in Australia. [6].

Behaviour and diet edit

The primary food sources for grey butcherbirds are insects; small vertebrates, such as lizards and other small birds and their chicks; and infrequently, fruit and tiny seeds. [7][9] Uneaten food can be kept in a branch fork to be eaten at a later time. Food that is too big to eat at one sitting can also be impaled or saved for later use. [7][9].

Grey butcherbirds sit in branches and wait for prey. The grey butcherbird sally-pouncing its prey on the ground, capturing it. [7] Sally-striking can be used to catch small birds and insects in flight[9]. [7] While the foraging birds are on the ground, the grey butcherbird ambushes them; it usually approaches and attacks from behind. [7] The grey butcherbird perches in small family groups, in pairs, or by itself. [9].
