Distribution and habitat

Commonly found between 1,900 and 2,300 metres (6,200–7,500 ft), but can be found in the range of 1,700 to 3,100 metres (5,600–10,200 ft). They are considered uncommon to fairly common in these ranges. They like to stay in brushy hillsides in the forests of Colombia, Ecuador, Peru, and Venezuela. Though they are common, they are rarely seen because they hide in the dense mountain understory.
Behavior
Foraging
The yellow-bellied chat-tyrant is a quiet, retiring bird that tries to stay hidden at all times. They tend to perch alone, fairly erect, 0.5–5 metres (1.6–16.4 ft) above the ground in mossy understory. They tend to flick their tails up and sally short distances in the understory while hunting insects in the foliage making audible snaps. They also will hop from twigs to the ground. They are sometimes considered fearless but typically inconspicuous, hiding in thick undergrowth. They can occasionally be found in mixed flocks, but do not follow them.
Vocalizations
In the morning (at dawn) this bird sings with a fast, thin, and delicate trill that ascends slightly like fingers running up a comb. During the day the song is a long, buzzy trill that sags in the middle then ascends at the end. There is also a longer version during the day that slowly rises then drops slightly at the end. It also has a "conflict" call that slowly rises then immediately followed is a slow descending trill over and over with other sharp bickering notes. The bird also will sing for a short time at dusk.
Breeding
They tend to breed from January–October in Colombia and March–December in Ecuador. They do not migrate, making them a resident bird. They tend to make mossy ball nests on banks containing 4 creamy white eggs.
