The Austin Roberts (Memorial) Bird Sanctuary is a 11.76 ha (29.1 acres) nature reserve located in the Walkerspruit Open Space System, in the Nieuw Muckleneuk suburb of Pretoria, South Africa.

He was born in Pretoria in 1883, but grew up in Potchefstroom as a minister's son, where the local amateur ornithologist, Thomas Ayres, was his mentor.

A former clay quarry at the confluence of Walker and Argo Spruit was allowed to fill with water, and some exotic trees were planted along its verges.

In addition nine small perennial dams or wetland basins have been created, some with artificial islands, to accommodate aquatic birds and animals.

[4] Resident or visiting passerine birds include thick-billed weaver, southern red bishop, common reed warbler, little rush-warbler and lesser swamp-warbler.
