Brian4all - from past experience, the non slr cameras I have used, it was always more difficult to get consistently sharp pictures.
With the SLR, you get full manual control, or aperture/shutter control and then you have a choice of which lens to use. My lens has very fast autofocus which is very handy with birds in flight which the non slr camera surely will lack.
I generally shoot aperture priority at about 5.6 to get the shots you see above.
I am not saying you wont get good shots shooting with your non slr, but I certainly think it will be alot harder and alot more frustrating. Just my opinion though.
