Anticipating movement and actionWhen I anticipate having action or significant movement of my subject(s) in my frame, I will always shoot in AI focusing mode (or Continuous mode on Nikon cameras). I try to keep my frames in more than 2 to 4 frame bursts, unless I am trying to isolate a very inique moment in time. When browsing through my images, I will tend to locate the images where my subject(s) look natural, the overall composition is pleasing, and there is some sort of dynamic element to the frame.
Shooting ModeI tend to use aperture priority mode most of the time when I am shooting wildlife. There is usually significant movement of my subjects in relation to my light source (the sun), and I find that I can change my exposure compensation much faster. You can read
my article on depth of field from an earlier post on this site.

MeteringThis is where I use many different approaches, depending on the situation. In fast changing light, I tend to use evaluative metering with some sort of exposure compensation. If the light is not changing quickly, I will tend to use evaluative or spot metering in manual shooting mode. My lazy shooting almost always happens in aperture priority mode with evaluative metering. Most subjects that are out on the Serengeti plains will be around a +1/3 exposure compensation, and those subjects that are darker than middle tones (elephants, wildebeest and rhinos) will have around -2/3 of compensation. All of the big cats (lions, cheetah and leopards) are close to middle tone, but I almost always add in an extra +1/3 of compensation to 'expose to the right'.
Camera and Lens stabilizationAlmost all of my wildlife photography in Africa is taken from a bean bag. There are so few opportunities to get out and use a tripod, and any other means of supporting your cameras and lenses just aren't as effective. However, east African safaris typically have enclosed Land Rover/Land Cruiser vehicles with pop-tops. These are very different from southern African vehicles with open sides. I will be in Botswana in a few months, and will figure out what works best during the safari. I will be prepared to use a variety of solutions, and will settle on one approach within the first few days.

Image StabilizationIn a few words, life would be much more difficult without image stabilization. I use it as often as I can.
Shutter SpeedI rarely let shutter speed be my first consideration in my photos. Well, unless I am deliberately shooting slow speed panning shots. I am usually more concerned with depth of field, and will use my ISO setting on my camera help me achieve my minimum shutter speeds. For some this may sound crazy, but I would rather have a sharp photograph with noise (think ISO 800 and 1/500 sec) than a photograph with no noise and a blurry subject (ISO 100 and 1/6o sec). I am not afraid to push my ISO to higher numbers on my Canon equipment, but with my recent use of the Nikon D2x I would hesitate in pushing past ISO 400.
