Hi,
I am very new here and have been using a point and shoot for a few years, my S5 IS and have finally bought my first used DSLR, a 300d. I am very very new to photography in a sense that I am trying very hard to learn all the ins and outs of it and want to make this a serious hobby. Taking nature/wildlife photography is really my favorite and birds are pretty high up on my list. It is a part of nature that I can capture in my backyard or close by in a forest preserve without having to spend a lot of money traveling to the local zoo to get shots although the zoo is my favorite place to visit.
Since I am just getting started and still learning everything about ISO, shutter speed and aperture I have been reading stuff on this message board like crazy and I am taking a basic intro photography non-credit class at my local college. It's still kind of confusing knowing what shutter speed and aperture to use for different kind of photos and situations.
I really want to get serious with taking good photos of birds and would like some suggestions as to the type of lenses that i would really need for some great close ups like I have seen posted here.
I know my Rebel is old, from 2003 but I wanted to know is it more about the length of the zoom lens or the actual body of the camera that can get these great shots I am seeing from all of you?Or, is a big zoom lens the absolute most important thing to start with?
I bought a Canon EF-S 55-250mm IS lens from someone on this board and it's being shipped to me today.
I already know that the 250mm lens will probably not be enough for very close bird shots because my S5 IS has a longer zoom on it that can go all the way to 432mm I believe, but I know the quality of the S5 IS cannot get me the shots I am seeing from your DSLRs.
Can some of you offer your suggestions as to what kind of lenses I would need to get some halfway decent bird shots and if you think that my old 300d body is capable of producing some great shots with a decent lens.
I am almost considering buying a powershot SX 30 IS for it's super zoom function, goes out to 832mm from what I have seen but again, I don't think the image quality would be the same as a DSLR, am I correct on this? I don't think I could ever afford a DSLR lens that went all the way out to 800mm.
Any tips on lenses that are not going to cost an arm and a leg for a DSLR would be much appreciated.
Thank you so much for any help you give me.

when I have to try and figure out if I want a large or small aperture and why, and the same thing with the shutter speed decisions. So I figure a lot of it will be by trial and error.
