African Birdlife
|July/August 2023
I observed an interesting scene at KwaMaritane camp in Pilanesberg, North-West Province. A Grey-headed Bush-shrike had caught a large caterpillar and wedged it between a small branch and the trunk of a tree
-
It then proceeded to apparently degut the caterpillar, pulling out strands of intestine. It wasn’t completely clear what happened to these strands, but they did not appear to be consumed by the bird; I assume they were toxic in some way. The bush-shrike then consumed the degutted caterpillar in pieces.
I can’t find any record of this behaviour in Tony Harris’s Shrikes of Southern Africa and would be interested in comments on this observation.

ALTHOUGH I HAVE been taking photographs since 1998, it wasn't until 2019 that my hobby evolved into a serious pursuit. That's when I began to see photography not just as a means of capturing a moment, but as a form of art - something that can stir emotion, spark wonder and tell a deeper story.

PREDATORS of the pan
As regular visitors to Mabuasehube in the Botswanan sector of the Kgalagadi Transfrontier Park, we have often seen vulture feathers lying in the area of the waterhole at Mpayathutlwa Pan and have frequently observed a pair of black-backed jackals in the vicinity.

grassland GLADIATORS
The Secretarybird is a highly soughtafter species for most birders on their first visit to Africa. It looks so strange, like a cross between a stork and an eagle. Even though it is widespread, occurring in almost any suitable habitat (grassland, open savanna and Karoo shrubland), it's generally uncommon.

Autumn is generally known to be quieter in terms of rarities across southern Africa, but the review period still had a few surprises for us, including a new species for the subregion. As always, none of the records included here have been adjudicated by any of the subregion's Rarities Committees.
