On some evenings in late October, the central Zambezi woodlands in northern Zambia start to feel a little unsettled. At first it is not visible. It’s more a change in pressure, as if the forest has taken in too much air and is holding it in. Inside Kasanka National Park, branches bend under invisible weight and before anything can move, sounds start coming from the canopy.As reported by the BBC, from the platform of Musola Hid, the perch is partially visible, although “visible” is generous. The trees are packed so tightly that the movements of bats become apparent. At rest they merge into wood and shade. Then, gradually, the first separation occurs. One or two lifts, hesitation, and went away. After that the hesitation goes away.
seasonal arrival of Africa’s largest bat colony
Its habitat is in dense swampy forest, where daylight barely reaches the ground in any consistent manner. The trees grow close to each other, the branches intertwine, and the whole space feels a little compressed even in daylight. When bats roost during the day, it is not easy to identify them as individuals. They form mass first, expand later. At some angles, the weight itself pushes them away. The branches bend in a way that doesn’t look natural, bending beneath what appears to be nothing until the eye adjusts.Then the evening changes everything. Not suddenly, but in stages that are easy to miss unless you are already looking closely. Straw-coloured fruit bats, or Eidolon helvum, arrive seasonally at Kasanka, drawn by the fruit circle in Central Africa. By the time they inhabit the park, their numbers are often estimated in the millions, although no one presents this figure with much confidence. It’s very big, very fluid.They eat a heavy meal, then move on. In a single night, large colonies can snatch, eat, and disperse large quantities of fruit from surrounding forests and spread the seeds far and wide. This process is less streamlined than it seems. It’s messy, repetitive and constant.
Discovering Kasanka’s Lesser Seen Wildlife
Away from the main habitat, the landscape changes to papyrus channels and flooded grassland. Early morning is the best time to pay attention to anything here, when the mist is less and the water feels closer than it should. This is where Sitatunga usually appear without warning. A woman first, careful and slow. Then smaller animals, and sometimes a male with spiral horns who grips the reeds as he walks. They don’t last long. Once the area is recognized, they move back into the plants which close behind them.Wetlands also hold more than antelope. The hippos move into the deeper waters nearby, mostly invisible except for sound and the occasional break at the surface. Bird life constitutes most of the visible activity, with hundreds of recorded species passing through the different layers of the park.
The return of Zambia’s hidden forests
By the late 1980s, Kasanka had changed substantially. Due to illegal hunting, the wildlife population had declined rapidly and large parts of the park had become almost empty. For a period, its status as a functioning national park was uncertain. Reconstruction took place in phases rather than as a single intervention. Under the new management, infrastructure was gradually restored, basic routes reopened and security strengthened. Wildlife began to return, albeit unevenly. Some species recovered faster than others.Today, visitors often stay at Wasa Lodge, a lakeside base where water and forest meet without any clear boundaries. Nights there are rarely quiet in the traditional sense. Hippos, insects, distant rustling in the reeds. The forest is never completely at peace.
