Unknown bird??!!

I received this image recently from my aunt who is based on a game farm near Phalaborwa. The family she is living with have rescued a number of birds, mostly chicks, that have been blown out of their nests in storms.

This little one was a recent addition to their collection, and they cannot place the species. Can anyone out there put a name to this bird? Please post a comment below the picture or email me directly at stuartgroom@xsinet.co.za . Thank you!!
