These were seen on my recent trip to the Terrick Terrick National Park, about 10 km away as the crow flies. (30 if you go by road).
This is a prickly pear (Opuntima, I think). It a very invasive plant and illegal to cultivate. The ‘pears’ are apparently edible. There were a few plants growing wild.
My husband spotted this bird. I don’t know what it is. Any ideas?
