Calamonastes fasciolatus (near-endemic)
This near endemic, prinia-like warbler is a common resident in dry acacia savanna.
I first saw it near Nxai Pan in Botswana in April 2011. The camp we were staying in had a dumping ground, which attracted many flies and insects. This little skulker was taking full advantage of the insect fest and allowed me to take some close up photographs.
