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.

Common Poorwill
Phalaenoptilus nuttallii
Small, compact night bird with short wings and tail. Intricately patterned with shades of gray; flight feathers are barred with rufous. Males have white corners on tail, females have browner tail corners. Named for its song: a whistled "poor-WILL," sometimes with a faint third note. Strictly nocturnal; more often heard than seen. Prefers rocky desert slopes with some dry vegetation; sometimes perches prominently when singing but also sings from the ground.

Pacific Antwren
Myrmotherula pacifica
A small, short-tailed antwren found from western Panama to Ecuador. Male is entirely streaked black and white, with two white wingbars. Female is similarly streaky, but has an orangey head. Occurs in lowlands and foothills, up to around 1,300 m. Look for pairs in the lower levels of forest edge and second growth.

Sokoke Scops-Owl
Otus ireneae
A small owl with a tiny range along the East African coast. Note the yellow eyes, the small ear tufts, and the fine spotting below. The coloration varies from gray to dark brown to bright rufous. Found very locally in coastal forest. Often found roosting in pairs or family groups in the forest's lower levels. Similar in appearance to African Scops-Owl, but found in different habitats, and separated by the spotted rather than striped underparts. The call is a series of tooting notes, reminiscent of a tinkerbird or pygmy-owl.
