Trying to find a camera to meet these needs...

[scukr]

I am planning a special trip late summer. Can't take a lot of stuff, so I am leaving my big camera home. Need a zoom as big as I can get for wildlife. Which camera will give me good quality, big zoom, good battery life, big enough cards that I can use to hold photos until I can download them to my portable hard drive, and be small enough that I could carry it in my purse without feeling weighed down. My favorite camera right now is my Olympus Stylus Verve, but zoom is not good enough. Please advise.
