Outside the small town of Nigel, is the popular Marievale Bird Sanctuary. Habitats of the sanctuary include shallow open water, reedbeds and grassland, so the variety of birds is immense. Approximately 1 000 hectares in extent, the sanctuary supports about 180 species, of which 65 are waterbirds, including large populations of Reed Cormorant, Red-knobbed Coot and Yellow-billed Duck.
Marievale has been documented as being one of the best locations in Gauteng to see Goliath, Black, Squacco and Purple Herons. Along with the five hides overlooking four pans, there is a braai and picnic spot with ablution facilities. To maximise your stay, you can overnight in the reserve in one of the two chalets which can be booked through Suikerbosrand Nature Reserve.
What a pleasant surprise Marievale turned out to be. It will be evn better in Summer.

You are right Sharifa. I have done it in my Getz and found the midddle-mannetjie wasn't too high either.
and I also found a BSK nest there. The next hide is where I found Banded Martin diving for fish..
