Rwanda's fast decreasing Twa pygmies, are living on the fringes, facing poverty and disrimination.
A small community eking out a frugal living on the flank of an impossibly steep hill in Bwiza in the centre of the country embodies the problems they face in post-genocide Rwanda.
Bwiza's residents came to look for a field, having lost the land their families owned decades back.
They are plagued by alcoholism, lose up to two children for every one born and have little or no access to health care.
"A lot of children die. I used to have nine, now I have three," said Jowas Gasinzigwa, leaning on a crude walking stick.
There are 46 families and just 50 children in the hamlet, 15 of whom attend school. All this in a country where most women produce five or six children.
"I now have three and I used to have six," said Celestin Uwimana, 38. "Many die of malaria because they don't go to hospital when they have it. Others get meningitis."
The nearest health centre is a two-hour walk away. The pygmies live in leaf huts and respiratory diseases are a major scourge due to leaky roofs and damp.
Zephirin Kalimba, the head of an organisation that helps Twa communities through development projects, says they make up between 33,000 and 35,000 of Rwanda's 10 million people.
Whereas the overall population of Rwanda is on the rise, the number of pygmies is declining, a development likely linked to their displacement from their original forest lands and the end of their traditional hunter-gatherer lifestyle.
Though Twa used to own land, more than 40 percent of Twa households in Rwanda are today landless. They were forced out of forests which were turned into natural parks. It was only after eviction from their ancestral land that they turned to farming in fits and starts.
In Bwiza, the men, in gumboots or plastic sandals, sit in the shade complaining. It is the women who hoe a nearby field belonging to a Twa widow who inherited it from her late non-Twa husband, babies strapped to their backs in the blazing sun.
Both groups occasionally burst into laughter, start dancing and make up a song as they go along: about how "the minister said the Twa need iron sheets for the roofs of their houses" and how "Rwanda has many doctors, but none near Twa villages".
Kalimba said the community should be afforded benefits given to handicapped people or women in Rwanda. Instead, the Twa are practically excluded from government poverty alleviation measures, he claimed.
The pygmies even had to change the name of their organisation, the Community of Indigenous Rwandans, as the government argued that identification along ethnic lines contributed to the 1994 genocide that killed some 800,000 people.
The first recorded reference to pygmies appears to be in a letter written in 2276 BC by the boy pharaoh Pepi II. More recently the French-American explorer Paul du Chaillu wrote at length about his encounter with pygmies in the rainforests of Gabon in 1867.
But their short stature has long set them apart, and at times seen them stigmatised. Pygmies were on occasion displayed in zoos or circuses as curiosities and are often considered in their native Africa as either sub-human or possessed with special powers.
The present day Twa try to eke out a living from casual labour and pottery.
When the Twa, who are also found in neighbouring Burundi, Democratic Republic of Congo and Uganda, can get work it is usually on their neighbours' land and the pay is a pittance.
They complain of persecution both at work and in school.
"If we go to look for labour where someone is building a house, they'll only take us if there are no non-Twa workers," Uwimana said.
"When we earn some money cultivating a communal field ... and we try to put it into the bank, we go to the bank counter and they say, 'Ha, you're a Twa' and refuse to open an account," he added.
In despair, some of them have turned to drink.
Asked if the same holds true in schools, 14-year-old Justin Nzabandora said the main Twa children so often drop out of school is because "they get tired of having other children point to them saying 'look it's a Twa'."
