Eremomela scotops
This beautiful eremomela can be easily separated from s its yellow-bellied and burnt-necked cousins by its greenish crown, yellow breast and olive back. They are not the easiest birds to photograph, given that they feed in the canopy of broadleafed woodland and are constantly on the move.
I first recorded this species in August 2011 while birding Mabusa Nature Reserve in Mpumulanga with Skye Hartog. This reserve must be one of the best spots in South Africa to reliably see them.
