Photographing wildlife needs the photographer to approach the subject stealthily. One needs immense patience & good presence of mind to get good photographs of wildlife. Often the birds, animals don’t entertain humans & at times they may even get on defense & counter-attack. Happened to me once. I was in a balcony shooting a small bird perched on a nearby power line. To get closer, I went into the balcony, crouched & just held my hand up. As I fired a shot, another shot the bird got furious & decided to attack the camera however it missed. As I got up to go inside, it again flew furiously just across my face. A split second delay in my reaction would have got me injured near or on my eye. Thankfully I was safe. So the point of telling you this short tale is that one needs to approach the wildlife in a way that it is unaware of you. When you are successful in doing so, you will get good shots as the wildlife won’t be scared or put on a defensive mode.
