The Bundok flycatcher (Ficedula luzoniensis) or thicket flycatcher, is a species of bird in the family Muscicapidae. It is endemic to the Philippines found in tropical montane forest.

EBird describes the bird as "A small bird of montane forest undergrowth, where it perches motionless for long periods. Sooty-gray above with white under the base of the tail and on the belly blending to an orange chest and throat, slightly paler on the chin. Most races have a short, thin white eyebrow. Similar to Mugimaki Flycatcher, but has pinkish rather than black legs and lacks any white marks in the wing. Song is a simple, very high-pitched whistled melody.^[2]

Eight subspecies are recognized:

• F. l. luzoniensis — Found on Luzon and Mindoro
• F. l. calayensis — Found on Calayan Island
• F. l. rara — Found on Palawan
• F. l. nigrorum — Found on Panay and Negros
• F. l. daggayana — Found on Misamis Oriental
• F. l. montigena — Found on Mount Kitanglad and Mount Apo
• F. l. malindangensis —Found on Mount Malindang
• F. l. matutumensis —Found on Mount Matutum

Feeds on mostly on small insects but also some fruit. Found singly most of the time but seen in pairs during the breeding season. This species silently forages low in clearings and forest edges - it is often seen on the ground while also hawking for insects. Birds in breeding condition with enlarged gonads collected from January to June. Young birds have been observed in May to June. No other information regarding its breeding habits. ^[3]

Its natural habitats at tropical montane forests typically above 1,000 meters above sea level. The supposed subspecies calayensis is virtually unknown and an exception to this as Calayan Island's highest point is just less than 500 meters above sea level.

The IUCN Red List has assessed this bird as least-concern species as it is still common across its range. However, the population is believed to be declining due to the deforestation happening throughout the Philippines.^[4]
