I had to scroll through hundreds of Botswana bird photos to identify this white-crested helmetshrike, that I took a picture of long ago. (Googling ‘White bird with orange-ringed eye’ and several other similar attempts, did not do it).
We call a shrike laksman (say ‘la- ks-mon’) in Afrikaans: literally, executioner. The crimson-breasted shrikes in our garden in South Africa would find frogs or big insects, and impale them on the thorns of a bush before devouring them!
White-crested helmetshrike (Prionops plumatus), Tuli Block, Botswana, Jul. 1988.
