Victorin's warbler Cryptillas victorini

A skulky brownish warbler with a ragged tail, warm cinnamon-buff underparts, and a distinctive gray face with a pale yellow eye. It is restricted to damp fynbos, especially boggy areas with sedges and Berzelia, and fern-filled glades along forest edges, where it creeps about mouse-like and is almost always first detected by its characteristic song. This is often rendered as a loud, lilting, melodious “sip-sip-silly-slip-slip, sip-sip-silly-slip-slip” that often continues for over a minute and then often ends with a harsh dry “tsit-chirrit-chirrit” or similar calls. Victorin’s Warbler is most easily found from August to November, when it is singing most frequently.
