Just to stick my oar in,200mm will be next to useless for birds after you have captured the first few easy ones,go through the birds thread on here and look at the Exif,300mm is just starting to become useful i did start with that myself,a mixture of cropping and creeping up will get you some good images.
I started with the 55-300 vr my suggestion would be wait and get that,better than buying one you will soon outgrow.
