Description and taxonomy

EBird describes the bird as "A fairly small bird of lowland and foothill forest floor or dense undergrowth. Warm brown on the upperparts, crown, and sides, with fine buff streaks on the sides and blackish underparts heavily streaked white. Note the contrasting white throat, the black-and-white moustache stripes, and the white stripe from above the eye to the back of the head. Unmistakable in range. Voice includes a variety of medium-pitched whistles, including repeated piping, downslurred notes, plus complex jumbled songs and imitations of other bird species."^[3]

Subspecies

Four subspecies are recognized:

P. m mindanensis – Found on Mindanao except Zamboanga Peninsula; pale streaking
P. m. basilanica – Found on Zamboanga Peninsula and Basilan; similar to the nominate with pale streaking and back
P. m. minuta – Found on Leyte and Samar; smaller wih darker shaft streaks
P. m. fortichi – Found on Bohol; similar to minuta but crown and back is darker

Ecology and behavior

Breeds in January to August. Nest is described as a dome shaped cup made of dead leaves. roots and small twigs on the forest floor or up to 3 meters high in the leaf base of palms. Lays 1 bluish tinged white egg with brown spotting and lines. ^[4]

Habitat and conservation status

It is found in tropical moist lowland forest with dense understory up to 1,400 meters above sea level but more common below 1,000 meters. Forages in the low forest floor and turning over leaves.^[2]

IUCN has assessed this bird as least-concern species but the population is decreasing. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. The most affected part of its range is Bohol which only has 4% forest cover remaining.

Occurs in a few protected areas like Pasonanca Natural Park, Mount Apo and Mount Kitanglad on Mindanao, Rajah Sikatuna Protected Landscape in Bohol and Samar Island Natural Park but actual protection and enforcement from illegal logging and hunting are lax^[5]
