==Description==

The round-tailed manakin is {{convert|10.5|to|11|cm|in|sigfig=2|abbr=on}} long and weighs about {{convert|16.5|g|oz|sigfig=2|abbr=on}}. The species is sexually dimorphic. Its tail has a rounder end than those of other ''Ceratopipra'' manakins. Adult males have an almost entirely red head and neck. Their thighs are creamy yellow. Their throat and the rest of their plumage are black. Adult females are mostly dull olive-green; their underparts are lighter than their back, especially on the belly. Both sexes have a blackish bill and smoky pinkish legs and feet. Males have a white iris and females a grayish one. Immature birds of both sexes resemble adult females but with a darker gray iris.<ref name=RTMA-BOW>Snow, D. (2020). Round-tailed Manakin (''Ceratopipra chloromeros''), version 1.0.

==Distribution and habitat==

The round-tailed manakin is found from southern Amazonas Department in eastern Peru south through extreme western Acre in Brazil and into northern Bolivia as far as western Santa Cruz Department. It inhabits humid forest, of both ''terra firme'' and seasonally flooded types, in the lowlands and Andean foothills. In elevation it reaches {{convert|1500|m|ft|abbr=on}}.<ref name=RTMA-BOW/><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 round-tailed manakin is a year-round resident.<ref name=RTMA-BOW/>

===Feeding===

The round-tailed manakin's diet and feeding behavior are not known. They are assumed to be similar to those of other ''Ceratopipra'' manakins, for one of which see here.<ref name=RTMA-BOW/>

===Breeding===

The round-tailed manakin's breeding season spans at least August to November in southeastern Peru. Males display to females in a large lek. Display elements include flights back and forth between perches, swooping flights, and, upon landing, turning around and prominently displaying their yellow thighs. Nothing else is known about the species' breeding biology.<ref name=RTMA-BOW/>

{{birdsong|url=https://xeno-canto.org/species/Ceratopipra-chloromeros |species=the round-tailed manakin}} ===Vocalization===

The round-tailed manakin sings "variable high metallic sounds, mellow whistles, squeaky chatters, and buzzes". Two vocalizations are "a buzzy ''tsuk'ZRRRT''" and a "high rising-falling laugh".<ref name=Schulenberg/>

==Status==

The IUCN has assessed the round-tailed manakin as being of Least Concern. It has a 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 "locally fairly common" in Peru and rare in Brazil.<ref name=Schulenberg/><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 =278–279 | isbn =978-0-19-530155-7 }}</ref> It occurs in at least two protected areas in Peru.<ref name=RTMA-BOW/>
