Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Crested shriketit

The crested shriketit (Falcunculus frontatus) is a bird endemic to Australia where it inhabits open eucalypt forest and woodland.

Taxonomy and distribution[edit]

Recent work with nuclear gene sequencing suggests that the crested shriketits and the wattled ploughbill may require their own family, Falcunculidae (Dickinson 2003). There are three subspecies (sometimes considered full species) with disjunct ranges:[2][3]

  • Western crested shriketit (F. f. leucogaster) - sparsely distributed in south-western Western Australia
  • Northern crested shriketit (F. f. whitei) - rare, with isolated records in the Kimberley region of north-western Australia and the Top End of the Northern Territory
  • Eastern crested shriketit (F. f. frontatus) - the stronghold of the species in south-eastern Australia from the Lower South-East of South Australia, coastally and in the Murray-Darling Basin to south-eastern Queensland, with some scattered occurrences further north and west in Queensland

Description[edit]

Males are larger than females in wing length, weight, and bill-size.[4] Males have black throats, while females have olive green.

Behaviour[edit]

Male eating a caterpillar

It feeds mainly on insects, spiders and, sometimes, particularly during the breeding season, young birds. Thistles are also taken. It has a parrot-like bill, used for distinctive bark-stripping behaviour, which gains it access to invertebrates.

Status and conservation[edit]

The eastern crested shriketit is evaluated as being of least concern on the IUCN Red List of Threatened Species, the northern crested shriketit is considered endangered, and the western crested shriketit is listed as near threatened.[1] Both the northern and western crested shriketits suffer from habitat loss and fragmentation.[5]
