Western Fieldwren

Calamanthus montanellus

Small bird of open arid shrubland and grasslands in southwestern Western Australia. Pale brown above, whitish below, with distinct pale supercilium, streaking on head chest, and long, cocked tail. Forages quietly on the ground or in thick vegetation, where difficult to see. Most easily observed in spring when males perch up in vegetation to sing. Similar to Rufous Fieldwren but no range overlap. Compare Shy Heathwren, which has an unstreaked back and head, white wing spot and darker legs.

识别特征

The western fieldwren (Calamanthus montanellus) is a species of bird in the family Acanthizidae, endemic to southwestern Australia. It is often considered a subspecies (Calamanthus campestris montanellus) of the rufous fieldwren (C. campestris), most notably by Christidis and Boles in their 2008 work, but as a separate species by many other authorities including the International Ornithological Committee. A 2020 genetic and morphological analysis of the genus suggests that C. montanellus is a synonym of C. campestris, and that rather than consisting of seven subspecies, C. campestris comprises two mainland subspecies C. c. campestris and C. c. rubiginosus east and west, respectively, of 133 degrees longitude, and only one island subspecies, C. c. hartogi.
