The small lake forms a suitable habitat for diverse waterfowl. Top among these are the Pink-backed Pelican, both Grey and Black-headed Herons, Western Cattle Egret, Sacred and Hadada Ibis, African Spoonbill, Spur-winged and Egyptian Geese, Common Moorhen, and a host of less common species. Between the months of December and April a large breeding colony of Pink-backed Pelicans forms on the two small islands in the lake, here at the southern breeding limit for this widespread species. Lesser Swamp Warbler, Thick-billed Weaver and Southern Red Bishop breed in the extensive reedbeds surrounding the lake while Black Crake, Red-chested Flufftail and African Swamphen are occasionally heard from the dense marshes.

The gardens themselves support an interesting assemblage of forest and woodland species, though several obvious species are missing. Key species include the Red-capped Robin-chat, Southern Black and African Paradise Flycatchers, Kurrichane Thrush, White-eared Barbet, Bar-throated Apalis, Dark-backed Weaver, Southern Boubou, Purple-crested Turaco, Yellow-rumped Tinkerbird, Grey Sunbird, Olive Woodpecker, and Terrestrial Brownbul. Seeding grasses may yield the Bronze and Red-backed Mannikin, and occasionally the shy and sought-after Green Twinspot. Black Sparrowhawk regularly hunt through the gardens and at least two pairs are known to nest nearby. Southern Tchagra occurs nearby and is possible within the gardens, while Spotted Ground Thrush may wander through the area in the winter months.

Other fauna include a resident troop of Vervet Monkeys, which rain the gardens with the Ficus trichopoda trees come to fruit, and Water Mongoose in the vicinity of the small lake.
