Sighting of a melanistic Gabar Goshawk nearer home

One of my most enjoyable moments  while out birding and atlasing in the last two weeks; was a sighting of a melanistic form of a Gabar Goshawk within some few metres where I had spotted the normal one.
The last time, which was my first time, was at Kgalagadi Transfrontier Park.
This time it was spotted less than 20km from my home.

Melanistic form of Gabar Goshawk - a rare occurrence (less than 20km form my home)
