firstly you get 2 types of harlequin quail, firt i see people refer the montuzuma or mearns quail as the harlequin quail which I only saw on pictures and far as I know not availeble in South Africa the seconldly you get the african harlequin quail which is native to south africa which you must have a permit to keep it here are some pic with it
and here is the montezuma quail
I will not prefer to mix two different species with each other cause it will get bloody and I m not a forrunner for cross breeding
