Question for Old Kampala Primary School

I do remember that in the OKPS there were four groups , I.e when on the field, four different groups , I.e GREEN was Eagle, ORANGE was Heron, BLUE was a Flemingo, the fourth one I just can't remember it, if it was YELLOW = Crown Bird??
I had finished that school because the family had decided to move from Martini Road to Kira Road, Kololo
