We lived near an Ostrich farm while stationed in Montana, and I used to go over and photograph these strange and aggressive birds. From what I observed, they were easily irritated, and would kick viciously when bothered. They also have extremely hard beaks, and love to bite, nip, strike, and torment all who come near. I have a nice, long distance respect for this beautiful creature. I took my life in my hands to get some close up photos of their heads....after this experience, I invested in a zoom lens for my camera!
