When you are sitting outside in the evening you will see many bats take to the sky at dusk, swirling around, hopefully eating mosquitos. They spend the day here, in a long row of trees, right in downtown Niamey. (See a more close up photo at my place2place blog.)
They call it the tiger bush because of the stripy way it looks from the air. There use to be lions, but people have been living in West Africa for 2000 years, so most of the lions are gone. The giraffes are doing pretty well though. A couple hundred at last count, up from a low of sixty, ten years a ago or so. On this outing we saw eight or ten individuals.
