I also think that a Superzoom would be the way to go. If you are only going to use the automatic mode you defeat the purpose of getting a DSLR. I've got a Canon SX120IS that I carry around with me most of the time and with its 360mm equivalent lens it can take reasonable pictures of birds. Its point zoom shoot. Cost is about $150.
If she is going to really get into photography then i would suggest the T2i and the two lens kit. The 55-250mm kit lens is light can be used for birding in a pinch. To really be serious about birds you are looking for at least a 400mm lens and spending around a $1000 just for the lens, and the lens will weigh between 2and 4 lbs.
