BirdLife International

Butchart, S. & Symes, A.


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). The population trend appears to be increasing, and hence the species does not 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.

Australian ringneck

For the tropical parakeet species, see Ringnecked parakeet.

The Australian ringneck (Barnardius zonarius) is a parrot native to Australia. Except for extreme tropical and highland areas, the species has adapted to all conditions. Traditionally, two species were recognised in the genus Barnardius, the Port Lincoln parrot (Barnardius zonarius) and the mallee ringneck (Barnardius barnardi),[2] but the two species readily interbred at the contact zone and are now considered one species.[3][4] Currently, four subspecies are recognised, each with a distinct range.

In Western Australia, the ringneck competes for nesting space with the rainbow lorikeet, an introduced species. To protect the ringneck, culls of the lorikeet are sanctioned by authorities in this region. Overall, though, the ringneck is not a threatened species.


The subspecies of the Australian ringneck differ considerably in colouration.[2] It is a medium size species around 33 cm (11 in) long. The basic colour is green, and all four subspecies have the characteristic yellow ring around the hindneck; wings and tail are a mixture of green and blue.

B. z. semitorquatus, Perth, Western Australia

The B. z. zonarius and B. z. semitorquatus subspecies have a dull black head; back, rump and wings are brilliant green; throat and breast bluish-green. The difference between these two subspecies is that B. z. zonarius has a yellow abdomen while B. z. semitorquatus has a green abdomen; the latter has also a prominent crimson frontal band that the former lacks (the intermediate shown in the box has characteristics of both subspecies).[5] The two other subspecies differ from these subspecies by the bright green crown and nape and blush cheek-patches. The underparts of B. z. barnardi are turquoise-green with an irregular orange-yellow band across the abdomen; the back and mantle are deep blackish-blue and this subspecies has a prominent red frontal band. The B. z. macgillivrayi is generally pale green, with no red frontal band, and a wide uniform pale yellow band across the abdomen.[5]

The calls of the mallee ringneck and Cloncurry parrot have been described as "ringing",[5] and the calls of the Port Lincoln ringneck and Twenty-eight have been described as "strident".[5] The name of the twenty-eight parrot is an onomatopoeic derived from its distinctive 'twentee-eight' call (or 'vingt-huit', from an early French description).[6]

Call of the Australian ringneck

Taxonomy and naming[edit]

The Australian ringneck was first described by the English naturalist George Shaw in 1805. It is a Broad-tailed parrot and related to the rosellas of the genus Platycercus; it has been placed in that genus by some authorities, including Ferdinand Bauer.[7]

Currently, four subspecies of ringneck are recognised, all of which have been described as distinct species in the past:[4][8] (As of 1993, the Twenty-eight and Conclurry parrot were treated as subspecies of the Port Lincoln parrot and the mallee ringneck, respectively).[5]

The classification of this species is still debated, and recent molecular research has found that all subspecies are very closely related.[4] Several other subspecies have been described, but are considered synonyms with one of the above subspecies. B. z. occidentalis has been synomised with B. z. zonarius.[9] Intermediates exist between all subspecies except for between B. z. zonarius and B. z. macgillivrayi.[4][10] Intermediates have been associated with land clearing for agriculture in southern Western Australia.[10]

B. z. barnardi
(Vigors & Horsfield, 1827)


The Australian ringneck is active during the day and can be found in eucalypt woodlands and eucalypt-lined watercourses. The species is gregarious and depending on the conditions can be resident or nomadic. In trials of growing hybrid eucalypt trees in dry environments parrots, especially the Port Lincoln parrot, caused severe damage to the crowns of the younger trees during the research period between 2000–3.[15]


This species eats a wide range of foods that include nectar, insects, seeds, fruit, and native and introduced bulbs. It will eat orchard-grown fruit and is sometimes seen as a pest by farmers.[2][16]


Breeding season for the Northern populations starts in June or July, while the central and southern populations breed from August to February, but this can be delayed when climatic conditions are unfavourable. The nesting site is a hollow in a tree trunk.[17] Generally four or five white oval eggs are laid measuring 29 mm x 23 mm, although a clutch may be as few as three and as many as six.[18] Fledgling survival rates have been measured at 75%.[19]


Although the species is endemic,[20] the species is considered not threatened,[1] but in Western Australia, the Twenty-eight subspecies (B. z. semitorquatus) gets locally displaced by the introduced rainbow lorikeets that aggressively compete for nesting places.[21] The rainbow lorikeet is considered a pest species in Western Australia and is subject to eradication in the wild.[22]

In Western Australia, a license is required to keep or dispose of more than four Port Lincoln ringnecks.[23] All four subspecies are sold in the Canary Islands and in Australia,[23] and they are traded via the CITES convention.[24] The sale of the Cloncurry parrot is restricted in Queensland.[25] The Australian ringneck can suffer from psittacine beak and feather disease, which causes a high nestling mortality rate in captivity.[26]
