An adult Brown-chested Jungle Fflycatcher, spotted in  a tree near Wat Phra Sri Sanphet in Ayutthaya. It is 16 centimeters tall, has olive-brown upperparts, and greyish-white underparts with faint throat mottling and pale buffish-brown colouring on the breast and flanks.

It has a black beak, with a pale yellowish, lower mandible, though in its first winter, the lower mandible becomes also dark, as visible in this photo taken in the cold season.
