Taxonomy and systematics

Description
The black-billed treehunter is 20 to 20.5 cm (7.9 to 8.1 in) long and weighs 39 to 46 g (1.4 to 1.6 oz). It is a bulky, dark
Distribution and habitat
The nominate subspecies of the black-billed treehunter has the larger range. It is found on the east slope of the Andes from Sucumbíos Province in northern Ecuador south all the way through Peru to the Department of Puno. Subspecies T. m. striaticeps is found on the eastern slope of Colombia's Eastern Andes south from Boyacá and Casanare departments to near or into northern Ecuador. The species primarily inhabits montane evergreen forest and also occurs in secondary forest and in stunted forest along ridgetops. In elevation it ranges between 1,000 and 1,800 m (3,300 and 5,900 ft) in Colombia and 1,000 and 1,700 m (3,300 and 5,600 ft) in Ecuador and Peru.[5][6][7]

Breeding
The black-billed treehunter's breeding season has not been defined but spans at least from October to April. It is thought to be monogamous. It excavates a tunnel up to 1 m (3.5 ft) long in an earthen bank with a chamber at the end that it floors with leaf stems and sometimes thin sticks. The one known clutch was of three eggs. The incubation period and time to fledging are not known. Both parents provision nestlings.[5]
Vocalization
The black-billed treehunter's song is "an accelerating, then decelerating, slightly descending series of c. 10–13 sharp 'kyip' notes with [a] 'laughing' quality".[5] The notes are sometimes paired.[6]
