(Yeah, yeah, I know, I should write more often, but I getting very lazy, 
my English is getting worse and so do my writing skills…nothing last 
long in the jungle, my friend, very high turnover rates. Well, here we go…)
Darkness starts early in the jungle, way before the sunset. Around 
16h30-17h there is a sudden switch in noises; the bonobos search for a 
place to build their nests while the galagos jump out of their holes and 
begin to stretchpreparing themselves to forage under the stars. Below 
the canopy the absence of light is almost complete around 17h30, time 
when, if we are lucky and the bonobos have decided to go to sleep, we 
are heading back to camp.
Such was the situation some days ago, when my boss and I had nested a 
small party far south of the home range and 9km separated us from our 
bucket shower and our 60% manioc dinner. 2h walking, a couple icy water 
cups poured on our bodies and some beans, kwanga and mpondu later, we 
were ready to sleep 5h before coming back to the nest site. Oats, powder 
milk, bananas, instant coffee and ready to go.
The night before we managed to follow two adult females until they built 
they nests, so around 5h, we were ready below them to collect the early 
morning urine. In my case, mine made me wait for an hour, before she 
finally peed and I could try to catch a fair amount in a Haumania 
leaf…which I had to discard because she also shited on it…evil primates…
Then all the individuals started to go out of their nests, and looked 
around, apparently without much idea of what to do. While Ben, one of 
the adult males, started dragging branches all over the place, I spotted 
Zed, a subadult male whom I was gonna focal the whole morning. After 
some time resting on the ground, the party started moving towards the 
first feeding tree of the day, but Zed had other plans and went to find 
his own bopfumo (a tree of the Tiliaceae family with tasty sour red 
fruit, a member of the genus Grewia). Nina, an adult female decided to 
follow him and had a couple of copulations before started feeding. The 
rest of the party didn't take long to join them. While some females gged 
(genitor-genital rubbings, version bonoba de la tijera, vamos), Zed 
looked for a good spot in which Ben, his brother, let him alone. Uma, 
another adult female, after displace him a couple of times, decided to 
groom him briefly. So much activity! I thought. For most of the male 
bonobos, an average day is pretty solitary, often in the periphery and 
with no much social interactions, but of course, depends on the male, 
the party among other variables.
After a good breakfast, the bonobos decided to go to a nice clearance 
made by a fallen tree and groom for a couple of hours. While Zed and his 
mother gromed in the company of the other adults, I enjoyed watching at 
intervals how is younger brother and a juvenile female played up and 
down the trunk. At some point, the group vocalized and soon after, Rio, 
another female of the community joined the party as started promptly to 
be groom by Ben.
When the grooming bout was over, it was time to rest and pee, so we were 
ready and alert to collect our precious samples. The shift was almost 
over when the bonobos moved to another feeding tree and the hand over 
came while Zed played with his younger brother close to their mother. 
Time for the humans to go grooming, feeding and socialize.
