The Black-and-white Shrike-flycatcher or Vanga Flycatcher, is a species of passerine bird found in Africa, specifically Sierra Leone, Angola, Democratic Republic of the Congo, Uganda, Tanzania, Kenya, Malawi, Zimbabwe and Mozambique. It is often placed with the wattle-eyes and batises in the Platysteiridae family but may be more closely related to the woodshrikes and helmetshrikes.
I first bumped into the female of this “special” species while birding the lowland forests of Mozambique in 2015. I still need to get a photograph of the male.
