Story
Ese Eja means the people. It comes from their own word for themselves, and like the A'i, the Boe and the Kamëntsá, it is a name that declines to be a description of anything except being human.
The names others gave them are Chama, Huarayo and Tambopata-Guarayo. Those appear in the official and older record and are noted here only so a reader meeting them elsewhere knows what they refer to.
They live across the Peru-Bolivia border in the southwestern Amazon: around 1,687 in the Bolivian departments of Pando and Beni, and roughly 400 to 500 in Peru along the Tambopata and the Heath near Puerto Maldonado. About 2,100 people in total, split by a frontier drawn through their rivers.
The Ese Eja have something almost no people in this archive has, and it belongs in the first paragraph rather than buried in the language section: their language is in active use across every age group. In a collection of ninety peoples where the usual story is a few hundred speakers and a falling line, that is the exception worth naming first.
Ese Eja country is the lowland southwest Amazon: in Peru the Madre de Dios, Tambopata and Heath basins around Puerto Maldonado; in Bolivia the foothills and rivers of Pando and Beni along the Beni and the Madre de Dios.
The Heath is the border river itself, which puts Ese Eja settlements on both banks of a line that is a frontier to two governments and a waterway to the people living on it.
On the Peruvian side the territory sits beside the Tambopata and Bahuaja-Sonene protected areas, and Ese Eja land is bound up with one of the most biodiverse and most contested corners of the Amazon.
Contested, because this is Madre de Dios. The department is Peru's illegal gold frontier, and the pressure that shapes Harakbut country to the west reaches Ese Eja rivers too. The archive records basins, departments and protected areas by name, and publishes no community locations.

Language
Ese Eja belongs to the Takanan family, the small grouping of the Bolivian and Peruvian Amazonian piedmont that also holds Tacana, Cavineña and Araona.
It is written in Latin script, it has a published dictionary, and — the fact that matters most — it is reported in active use across all age groups. Children are learning it. That single sentence separates the Ese Eja from most of the peoples in this archive, where the recurring finding is a speaker count well below the population count.
Why it has held is not something the accessible sources fully explain, and this archive will not invent a reason. What can be said is that the population is small, relatively concentrated on particular rivers, and split across two states that have each reached them thinly — and that thin state presence, whatever else it has cost, has not replaced the language.
Spanish is the second language on both sides. The border means Ese Eja children are schooled under two national systems while speaking one mother tongue, which is the same structural problem the Cofán, Siekopai and Wajãpi entries describe.
The sources describe the Ese Eja as hunter-gatherers, farmers and fishers at once, and the order is worth keeping: this is a people whose economy did not convert wholesale into agriculture but added it.
Fishing carries particular weight. The Ese Eja are river people on the Tambopata, the Heath, the Beni and the Madre de Dios, and fish is the protein a household counts on. Gardens supply manioc, plantain and the rest.
That makes gold mining an existential economic problem rather than an environmental abstraction. Mercury from illegal mining across Madre de Dios enters the rivers, accumulates in fish, and arrives in the household through the food it depends on most.
Cash comes from craft, from wage work around Puerto Maldonado, and on the Peruvian side from tourism in one of the most visited biodiversity destinations in the Amazon — an economy that pays some Ese Eja to show a forest that gold mining is emptying a few rivers away.
Ese Eja making is the making of a river household: canoes, paddles, nets, traps, bows, baskets and the carrying gear that a fishing and hunting economy runs on.
Beadwork and feather ornament belong to dress, worn at community occasions, and craft sale supplies part of the household cash — particularly on the Peruvian side, where tourism around Puerto Maldonado and the Tambopata reserves brings buyers.
That market is worth naming honestly. Craft made for visitors is real work and real income, and it is also a channel through which a small people's designs travel without attribution. Ese Eja pieces sold in Puerto Maldonado as generic Amazonian craft have makers, and the archive names them wherever the record allows.
The accessible sources describe Ese Eja material culture more thinly than they describe their language and their rivers, and this section records that rather than padding it with what neighbouring Takanan peoples make.
The Ese Eja present is defined by gold on one side and a living language on the other.
Madre de Dios is the centre of illegal gold mining in Peru, and the mercury it puts into the water reaches Ese Eja rivers and Ese Eja fish. Road access, colonisation and the pressure on the protected areas the territory borders all press from the same direction.
Against that, the Ese Eja are one of the few peoples in this collection whose language is not in retreat. It is spoken by everyone, including children, and that is the single strongest indicator of a culture that will still be here in fifty years.
The Bolivia-Peru border remains the structural complication: about four fifths of the people live on the Bolivian side, roughly a fifth on the Peruvian, and every programme — land title, schooling, health — arrives from a different state depending on which bank of the Heath a family lives on.
Ese Eja fibre work is the fibre work of a fishing people: nets, lines, carrying baskets, hammocks and cordage, made from palm and forest fibre for use rather than display.
A fishing net is a textile, and in a household where fish is the protein it is the most consequential woven object anyone makes. It does not appear in collections and it is rebuilt constantly.
Cotton cloth is largely commercial now, as across the southwestern Amazon, and beadwork rather than weaving carries the figured work in Ese Eja dress.
No named figured weaving tradition is documented for the Ese Eja in the sources this archive can reach. That is recorded as a gap in the record rather than as a statement about the people, and it is precisely the kind of thing an Ese Eja reader would be right to correct.
The accessible sources describe Ese Eja subsistence, language and territory far more fully than their crafts, and set out no distinct Ese Eja ceramic tradition. The archive marks the gap.
Ceramics are used in Ese Eja households as everywhere in the southwestern Amazon. Use is not manufacture, and only the first is supported by anything consulted here.
A mobile fishing and hunting economy on several rivers has less use for heavy fired vessels than a settled one, which is a reason the record might be thin rather than proof the craft is absent. Silence in a description can mean absence or it can mean nobody wrote it down.
The section stays open for an Ese Eja potter or a firmly attributed museum holding.
Ese Eja music belongs to community gatherings, played on flutes, drums and rattles in the manner of the southwestern Amazon.
This section carries a happier note than most in the archive. Where elsewhere song is described as one of the last settings a dying language is still used at length, here the language is used everywhere, by everyone, every day. Ese Eja song is not a preservation strategy; it is what people sing.
Song attached to healing work belongs to those who do that work, is learned through apprenticeship, and is not performance. The archive records that the category exists and reproduces nothing from it.
A detailed ethnomusicology of the Ese Eja is not present in the record this archive can reach. Saying so is more useful than borrowing a neighbouring Takanan people's repertoire and relabelling it.
The sources record that the Ese Eja hold both Christian and their own traditional religious practice, and that both are present rather than one having replaced the other.
That is a more common situation across the Amazon than either missionaries or their critics tend to describe, and it is worth stating plainly instead of resolving into a tidier story.
Traditional ceremonial practice and the specialists who hold it are named here and not described. The archive publishes no account of what is done, said or used, for the ordinary reason: it belongs to the people who hold it.
Community gatherings are where a people of two thousand, split across an international border and several rivers, actually becomes one thing, and that social function is the part of ritual life this archive can record without taking anything.
This entry publishes no medicine. No plant is named as a remedy, and no part, preparation, quantity, combination or method appears anywhere in this profile.
The health question that dominates the present is mercury. Illegal gold mining across Madre de Dios discharges mercury into the rivers; it accumulates in fish; and fish is what an Ese Eja household eats. Exposure in this department is a documented public health problem, and it reaches people through the most ordinary act there is.
Healing specialists exist within the traditional practice the sources record alongside Christianity. The archive names the role and describes nothing further.
State services arrive through two national systems. On the Peruvian side Puerto Maldonado is reachable and the health network is real if strained; in Pando and Beni the distances are longer. A people of two thousand on both banks of a border river is served, in practice, by whichever country a family can get to.
Ese Eja houses are river houses: timber frames, palm thatch, raised where flooding requires it, built where a canoe can land and a garden can be cut.
Settlement follows the water, which in this case means the Tambopata, the Heath, the Beni and the Madre de Dios. A people who fish for their protein builds where the fish are, and the map of Ese Eja settlement is the map of those four rivers.
The Heath deserves a second mention here. It is the international border, and Ese Eja houses stand on both banks — which makes the architecture of this people a physical demonstration that the border is an administrative fact rather than a lived one.
Sawn board, corrugated sheet and concrete appear near Puerto Maldonado, as they do wherever a road and a town arrive. Further up the rivers the older materials continue, for the ordinary reason that they are what is there.
