Camera setting advice for safari

[LCPete]

Hi we are going to India soon hopefully to see Tigers and should see lots of Deer and Birds
I have photographed lots of Zoo animals but never done anything like this. Its a one in a lifetime trip so want to make sure I done mess up!
What sort of shutter speeds should I be using to shoot from the back of a jeep?
Am taking 100-400 with 550D for sitting targets and 70-200 F4 and 40D for things like running Deer.
At the zoo bracing myself I normally use the 100-400 for Big cats on F5.6 or 6.3 and shutter speed of 250 on One shot.
If the jeeps engine is running how much do I have to raise the shutter speed?
I have never managed to get shots of fast moving animals at the zoo but will try a shutter speed of 500 at 6.3 in AI servo with the 70-200 F4

Hopefully it will be nice and sunny so you probably could even get away with 1000th, especially if you up your ISO. Also if your zoomed right in it's a good idea to up your shutter speed accordingly. A good rule of thub is to always have a greater shutter speed than your focal length.This comabats the exagerated effects of camera shake.

I also recomennd switching to continous shooting, animals are unpredicatable and you might capture something you would have otherwise missed. If you're unsure you could try bracketing your shutter speeds.

Good idea about continous shooting will do that
the high ISO on the 550D is very good so that wont be a problem

shut the jeep off when you are taking pictures. the rumble of the engine will cause more camera motion than you want. If you're out at 400 you'll especially notice it.

Thanks

and take pictures in raw in case you need exposure correction
i prefer a darker pics that can be corrected than a blur one!
