==Distribution and habitat==

The dwarf tyrant-manakin is a bird of the western and central Amazon Basin. It is found from the southeastern third of Colombia south through eastern Ecuador and eastern Peru into northern Bolivia and east from there across southern Venezuela and Brazil.<ref name=DWTM-BOW/> In Brazil its range's edge in the north roughly follows from Roraima west of the Branco and Negro rivers to the Amazon River and south of it to the Atlantic in northeastern Pará and northern Maranhão. In the south its range roughly follows from Rondônia southeast to southern Mato Grosso and from there northeast to the Atlantic in Maranhão.<ref name=vanPerlo>{{cite book | last =van Perlo | first = Ber| title =A Field Guide to the Birds of Brazil | publisher =Oxford University Press | date =2009 | location =New York | pages =282–283 | isbn =978-0-19-530155-7 }}</ref>

The dwarf tyrant-manakin primarily inhabits the interior of humid ''terra firme'' forest and to a lesser extent ''várzea'' forest. It seldom is found at the forest edge or in clearings.<ref name=DWTM-BOW/> It is primarily a bird of the lowlands, reaching only {{convert|400|m|ft|abbr=on}} in Colombia, {{convert|400|m|ft|abbr=on}} in Ecuador, {{convert|800|m|ft|abbr=on}} in Peru, and {{convert|300|m|ft|-2|abbr=on}} in Venezuela.<ref name=McMullan>{{cite book | last1 =McMullan | first1 =Miles | last2 =Donegan | first2 =Thomas M. | last3 =Quevedo | first3 =Alonso | title = Field Guide to the Birds of Colombia | publisher = Fundación ProAves| date =2010 | location =Bogotá | pages =173 |isbn =978-0-9827615-0-2 }}</ref><ref name=Ridgely2>{{cite book | last =Ridgely | first =Robert S. | last2 =Greenfield | first2 =Paul J. | title =The Birds of Ecuador: Field Guide | publisher =Cornell University Press | volume = II| date =2001 | location =Ithaca | pages =562 | isbn =978-0-8014-8721-7 }}</ref><ref name=Schulenberg>{{cite book | last =Schulenberg | first =T.S. | last2 =Stotz | first2 =D.F. | last3 =Lane | first3 =D.F. | last4 =O'Neill | first4 =J.P. | last5 =Parker | first5 =T.A.

==Behavior== ===Movement===

The dwarf tyrant-manakin is a year-round resident.<ref name=DWTM-BOW/>

===Feeding===

The dwarf tyrant-manakin feeds mostly on small fruits and also includes some small invertebrates in its diet. It usually forages up to the forest's mid-story but will do so in the canopy.<ref name=DWTM-BOW/>

===Breeding===

The dwarf tyrant-manakin's only breeding record came from April in Ecuador. The nest was a very small cup made from rootlets placed about {{convert|1.5|m|ft|0|abbr=on}} above the ground in a sapling. Males have been seen displaying to females by flying straight up with quick wingbeats from a high perch and plunging back down to the same perch.<ref name=DWTM-BOW/>

{{birdsong|url=https://xeno-canto.org/species/Tyranneutes-stolzmanni |species=the dwarf tyrant-manakin}} ===Vocalization===

The dwarf tyrant-manakin is very difficult to see and is almost always only heard.<ref name=DWTM-BOW/> Its song is a "curt ''zweeh-wit'' (''wit'' much higher) or ''zweeh-dewít''". Its call is a "very high, hurried ''prutrut---''" with three to six ''rut'' notes.<ref name=vanPerlo/>

==Status==

The IUCN has assessed the dwarf tyrant-manakin as being of Least Concern. It has an extremely large range; its population size is not known and is believed to be decreasing. No immediate threats have been identified.<ref name=IUCN/> It is considered common in Colombia, Ecuador, and Brazil and fairly common in Peru and Venezuela.<ref name=McMullan/><ref name=Ridgely2/><ref name=vanPerlo/><ref name=Schulenberg/><ref name=Hilty/>{{overcite|date=October 2025}}
