Remarkably plain brown warbler whose most outstanding features are a finely speckled throat and a white outer tail. Found in the canopy of acacia trees at middle and high elevations. Slow-moving and inconspicuous. Usually seen singly or in pairs. Not very vocal, but does give a simple whistled song and ratcheting calls. Somewhat similar to Garden Warbler, but darker below, with white edges to the tail. Could also be mistaken for female Eurasian Blackcap, but lacks its rufous cap.
