350D is basically a very good 8MP APS-C sensor that comes with a lightweight body. It is a great DSLR for birding, especially if you don't need the 5fps capability of the 20D/30D. 350D+EF400mm f/5.6L is probably the lightest super telephoto prime birding combination for SLR users. Even though 350D officially only supports AF with lenses that have max aperture of f/5.6 or wider, it does focus reasonably well with a non-reporting 1.4x TC at f/8.
There are two weaknesses for this body:
1. Ergonomics are not the best. Changing the aperture in Manual mode is somewhat painful. However, for birding, I almost always use Av mode and let the camera pick the shutter speed.
2. Servo AF is weak. Especially when the background is not clear (e.g. blue sky).
