Can i take good quality photographs of Flying Birds? I have Nikon L120 with 21x zoom.?

You'll try and try and try, take 100 shots, and maybe get a blurry thing in the corner of the shot 1 time.

Your camera is, quite bluntly, the exact opposite of good for taking photos of flying objects. You have no control of anything other than zoom, you have no viewfinder, and it takes a week to focus on anything. At full zoom, you'd be lucky to even find a bird in the viewfinder, let alone take a picture.

You are going to have to learn the art of panning, which is going to be difficult with the camera held out at arm's length. You also need a fast shutter speed for the best results, and unfortunately, you cannot adjust that on your camera.

But who knows?, with enough attempts, you might get a good photo.

At close distance, not with lots of zoom, at the right time and place. I say you can take stunning photographs of pigeons taking off from the plaza in front of a cathedral with your camera.

How sad, I think this happens more then we know My son when a child and his Dad, rescued a Mud Hen at a lake that was tangled in a fish line, they brought it home in a paper bag, Took a long time to untangle, I was amazed the bird offered no resistance, they released it at a private pond.
