Chestnut-rumped Heathwren (Mt Lofty Ranges)  |  

Calamanthus pyrrhopygius parkeri (Hylacola pyrrhopygia parkeri)

Status: Endangered on the EPBC Act list

The Chestnut-rumped Heathwren is a small bird about 13 to 16 cm long. It has a wingspan of about 16 to 19 cm, and a mass of about 13 to 20 g (Higgins & Peter 2002). The adults are mainly brown or brownish-grey on the upperbody, and mainly white (in males) or buff (in females) with brown streaks on the underbody. Both sexes have a chestnut patch on the rump; a grey tip to the tail; a narrow off-white (in males) or buff (in females) stripe above each eye; reddish-brown, brownish-yellow or cream irides; and pink or pinkish-brown legs and feet. Immature birds can not be distinguished from the adults, but juveniles can be separated on the basis of their unstreaked and pale buff to cream underbody, and the less prominent markings on the face (Higgins & Peter 2002). The Chestnut-rumped Heathwren (Mount Lofty Ranges) occurs singly, in pairs and in small groups (Paton & Paton 1980; Reid 1976).

    Therefore; the lack of suitable patchy fire regimes in the remaining habitat isolates may also pose a threat to the long term survival of this subspecies (N Reid; pers comm. 2004).
    The main threats to this subspecies due to its close proximity to a growing urban area are the introduction of weeds; inappropriate fire regimes; and clearing and degradation of its habitat.
