==Taxonomy and systematics==

In 1760 the French zoologist [Mathurin Jacques Brisson](/source/Mathurin_Jacques_Brisson) included a description of the little chachalaca in his ''Ornithologie'' based on a specimen collected in French Guiana. He used the French name ''Le faisan de la Guiane'' and the Latin ''Phasianus guianensis''.<ref name=brisson>{{ cite book | last=Brisson | first=Mathurin Jacques | author-link=Mathurin Jacques Brisson | year=1760 | title=Ornithologie, ou, Méthode contenant la division des oiseaux en ordres, sections, genres, especes & leurs variétés | volume=1 | language=French, Latin | place=Paris | publisher=Jean-Baptiste Bauche | pages=270–271, Plate 26 fig 2 | url=https://www.biodiversitylibrary.org/page/36010766 }} The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen.</ref> Although Brisson coined Latin names, these do not conform to the [binomial system](/source/binomial_nomenclature) and are not recognised by the [International Commission on Zoological Nomenclature](/source/International_Commission_on_Zoological_Nomenclature).<ref name=allen>{{cite journal |last=Allen | first=J.A. | author-link=Joel Asaph Allen | year=1910 | title=Collation of Brisson's genera of birds with those of Linnaeus |journal=Bulletin of the American Museum of Natural History |volume=28 | pages=317–335 | hdl=2246/678 }}</ref> When in 1766 the Swedish naturalist [Carl Linnaeus](/source/Carl_Linnaeus) updated his ''[Systema Naturae](/source/Systema_Naturae)'' for the [twelfth edition](/source/12th_edition_of_Systema_Naturae), he added 240 species that had been previously described by Brisson.<ref name=allen/> One of these was the little chachalaca.

The little chachalaca was previously considered [conspecific](/source/conspecific) with the [speckled chachalaca](/source/speckled_chachalaca) (''Ortalis guttata'') and [buff-browed chachalaca](/source/buff-browed_chachalaca) (''O. superciliaris''). What is now the [chestnut-headed chachalaca](/source/chestnut-headed_chachalaca) (''O. ruficeps'') was previously a subspecies of what was then called variable chachalaca. (Confusingly, after the split the International Ornithological Committee (IOC) renamed ''O. motmot'' "little chachalaca" but the American Ornithological Society (AOS) and the Clements taxonomy retained the name "variable" for it.) As currently understood, the little chachalaca is [monotypic](/source/monotypic).<ref name=VACH-BOW>del Hoyo, J. and G. M. Kirwan (2021). Variable Chachalaca (''Ortalis motmot''), version 1.1.

==Description==

The little chachalaca is {{convert|43|to|54|cm|ft|1|abbr=on}} long and weighs {{convert|345|to|620|g|lb|sigfig=2|abbr=on}}. Its head is reddish chestnut, its upperparts reddish brown to gray-brown, and its underparts gray. Its central tail feathers are gray-brown and the outer ones rusty. Its primary flight feathers are dark brown. Its facial skin is dark slate gray.<ref name=VACH-BOW/>

==Distribution and habitat==

The little chachalaca is found from southern and eastern Venezuela east through [the Guianas](/source/the_Guianas) into northern Brazil and south to the Amazon River east of the [Rio Negro](/source/Rio_Negro_(Amazon)). The AOS considers it hypothetical in Colombia. It inhabits landscapes such as the undergrowth along rivers, in clearings, and abandoned pastures; dense [secondary forest](/source/secondary_forest); and coastal brush. It shuns the interior of dense forest. In elevation it ranges from sea level to {{convert|1700|m|ft|abbr=on}}.<ref name=VACH-BOW/><ref name=SACCcountries/>

==Behavior==
===Feeding===

The little chachalaca forages in trees or on the ground, usually in pairs or small flocks. Its primary diet is berries and fruits although it also eats flowers and leaves.<ref name=VACH-BOW/>

===Breeding===

The little chachalaca has been recorded laying eggs in May, September, and December in the Guianas; there are no data from elsewhere. It builds a small cup nest of roots, leaves, and sticks and places it fairly low in a shrub or tree. The clutch size is three eggs.<ref name=VACH-BOW/>

{{birdsong|url=https://www.xeno-canto.org/species/Ortalis-motmot |species=little chachalaca}}

===Vocalization===

The little chachalaca's song is "a loud, rollicking duet, a repeated 'WATCH-a-lak', which is mainly given at dawn and dusk".<ref name=VACH-BOW/>
