A blizzard of bats!

A blizzard of bats!

Each year during November and December an incredible wildlife spectacle takes place in Kasanka national park in Zambia’s central province. Eight million (!) straw coloured fruit bats (apparently the greatest concentration of mammalian biomass ever recorded) converge on the national park.

The bats roost in an area of evergreen swamp forest only about a hectare in size. Their bodies are packed tightly together as they jostle for the limited space among branches which often break off due to the sheer weight of the bats!

As dusk descends they take off from the sagging branches and within minutes the sky is filled with millions of bats flying in all directions, fanning out into the forest to feed on the wild fruit that is so abundant at this time of year.
