In all honesty, I nearly got killed by an Ostrich. They indeed do have very sharp talons.
My uncle used to raise ostriches. I had seen Swiss Family Robinson one too many times I guess because on one of my visits I was intent on riding an ostrich. As soon as I jumped that fence and turned around, I had an ostrich running at me full speed. I barely jumped out of the way in time, and hopped back over the fence only to notice a clean one foot slice of my t shirt and a matching surface scratch on my belly. To this day I have a respect for those creatures. Can be very dangerous.
