Watching a youtube video of an Indian rhino swimming in its pool at San Fransisco zoo, got me to thinking....... We all know that Indian rhino are more aquatic than its 2 African cousinfs, but are there any zoos that keep their African rhino in an enclosure, with a pool, pond, whatever you want to call it but an open stretch of water, not a wallow, but a deep pool? The only example that springs to mind is the white rhino enclosure at bioparc Valencia. http://www.zoochat.com/180/white-rhinos-taking-bath-66175/
The Cleveland Metroparks Zoo has a pool for their herd of Black Rhinoceroses. http://www.zoochat.com/557/cleveland-metroparks-zoo-black-rhinos-45635/ http://www.zoochat.com/557/cleveland-metroparks-zoo-45659/ The Cincinnati Zoo also has a pool for their Black Rhinoceros, but it's much smaller and I've never seen him use it.
The North Carolina Zoo has a giant watering hole in it's 37 acre mixed species exhibit featuring 7 species of antelope (Gemsbok, blesbok, sitatunga, defassa waterbuck, nile lechwe, greater kudu, thomson's gazelle) along with 9 white rhinos. In my first and only visit a few weeks ago, about half the Rhinos took a nice dip in the watering hole around 4:30 pm. Needless to say they scared the bejesus out of every waterbird in site when they came galloping into the water.
