I have been monitoring the bird since then and I am happy to report that it is still in the same spot.
Although, there is another pair in the area; its call is still prevalent, displaying in fluttering flight low over grass, clapping wings and taking refuge at the top of the bushes. In Setswana (Chuana the local people and language) the bird is called Mantsiditsidi.
Lets take cognisant of the fact that the bird is near threatened.
