The Nukak people (also Nukak-Makú) live between the Guaviare and Inírida rivers, in the depths of the tropical humid forest, on the fringe of the Amazon basin, in Guaviare Department, Republic of Colombia. They are nomadic hunter-gatherers with seasonal nomadic patterns and practice small-scale shifting horticulture. They were classified as "uncontacted people" until 1981, and have since lost half of their population primarily to disease. Part of their territory has been used by coca growers, ranchers, and other settlers, as well as being occupied by guerrillas, army and paramilitaries. Responses to this crisis include protests, requests for assimilation, and the suicide of leader Maw-be'. An estimated 210–250 Nukak people live in provisional settlements at San José del Guaviare, while about as many live nomadically in the Nukak Reservation (Resguardo).
Hunting
Nukak are expert hunters. The men hunt with blowguns that shoot darts coated with curare "manyi", a poison made from different plants (curares). They hunt, in particular, several species of monkeys (Alouatta spp., Cebus spp., Saimiri sp., Lagothrix spp., Ateles sp., Saguinus spp., Callicebus torquatus), and birds (Muscovy duck, chachalacas, guans, curassows, grey-winged trumpeter and toucans). They also use javelins made out of Socratea exorrhiza palm wood to hunt two species of peccaries (Tayassu pecari and T. tajacu) and spectacled caimans, whose eggs they consume. Nukak neither hunt nor eat brocket deer, Odocoileus virginianus, and tapirs (Tapirus terrestris); they consider these animals to share a common ancestor with humans.
The Nukak also capture rodents (Cuniculus sp., Dasyprocta spp.), armadillos (Dasypus sp.), tortoises (Geochelone sp), frogs (in large quantities), crabs, shrimps, snails, larvae of palm weevils (mojojoy, "mun", Rhynchophorus spp.) and larvae of several species of wasps and caterpillars.
Fishing
The Nukak eat several species of fish, like Hoplias sp., Myloplus spp., Mylossoma spp., Hydrolycus sp., Cichla sp., surubí (Pseudoplatystoma fasciatum), catfishes (Brachyplatystoma spp.), piranhas (Serrasalmus spp., Pygocentrus spp.) and river rays (Potamotrygon sp.). Fishing is partly done with cord and metal fish hooks, although the Nukak still catch their fish traditionally with bow and arrow or harpoons, traps, or baskets ("mei", water cages). They also use a sophisticated technique that has been reported in several cultures: it uses nuún, the root of a Lonchocarpus sp. that contains a number of substances that when dissolved in the water streams stun the fish, making them easy to catch.
Gathering
They collect honey of twenty species of bees and many fruits: palm fruits (Jessenia bataua), Oenocarpus spp., Attalea spp., Mauritia sp., Phenakospermum guyannense, Aechmea sp., Inga sp., Couma macrocarpa, Iryanthera sp., Theobroma spp., Pourouma spp., Parinari sp., Micrandra sp., Helicostylis sp., Caryocar sp., Talisia sp., Hymenaea sp., Dacryodes spp., Abuta sp., Eugenia spp., Touraleia sp., Perebea spp., Protium sp., Cecropia sp., Batocarpus sp., Hyeronimasp., Brosimumsp., Dialiumsp., Garciniasp., Manilkarasp., Naucleopsisspp., Pradosiasp., Pouteriasp., Salasiasp., Passifloraspp., Duroia maguirei, Duroia hirsuta, Mouririsp., and Alibertia sp.Gutiérrez, Ruth 1996: "Manejo de los recursos naturales (fauna y flora) por los Nukak"; Bogotá: Universidad Nacional de Colombia, mec.
Nukak take the sweet resin from "mupabuat" (Lacunal sp.) and the rattan water (Doliocarpus sp.). They cover their encampments ("wopyi") with leaves of Phenakospermum guyannense and palms, and make their hammocks with fiber of the cumare palm Astrocaryum sp.; moorings with Heteropsis tenuispadix, Eschweilera sp., and Anthurium sp.; blowguns with Iriartella stigera, Bactris maraja; bows with Duguetia quitarensis; axe ends with Aspidosperma sp.; darts with thorns of Oneocarpus sp.; dart quivers with leaves of Calathea sp.; milkweed with Pachira nukakika, Ceiba sp., and Pseudobombax sp.; loinclothes for men with Couratari guianensis; baskets with Heteropsis spp.; disposable bags with Ischnosiphon arouma and Heliconia sp.; soap with Cedrelinga sp.; perfumes with Myroxylon sp. and Justice pectoralis; and diverse objects. Iryanthera They make blades with the teeth of piranha but have also adapted to use metals. Until 1990 they practised small-scale pottery, producing a small kind of pot to take with them on their travels and a second, bigger kind, to leave as supplies in their camping sites. Today they prefer to obtain metallic pots. When they do not have matches or lighters, they use special wood (Pausandra trianae) to produce fire. They no longer make mirrors with the resin of Trattinickia glaziovii or stone axes.
