Harmut Kolb reported seeing two Yellow-billed Oxpeckers on a donkey in the vicinity of Purros in the Kunene Region on 17/09/2011. These birds were about 200 km south of their recorded SABAP1 range. Peter Morgan and some of his Kunene River Lodge guests saw a Slaty Egret on the Kunene River about 1 200 m upstream from the lodge on 21/09/2011. None of the distribution maps in Roberts VII, SABAP1 or any of the field guides show this species occurring anywhere near where this bird was sighted. Mark Boorman, however, referred me to a paper published in the Bulletin of the African Bird Club (Vol 17 No 1 March 2010) wherein mention is made of four Slaty Egret specimens in the museum at Lubango in Angola.
