Jane, if reducing weight is really important you at least should look at MFT options. I have a Canon 80D and recently a Panny G9 (20 MP). You can save some weight with the Canon mirrorless bodies but the real weight is in the lenses. I love my Canon 100-400L but it weighs abt 47 oz versus the equivalent MFT Panny Leica 50-200 lens at half the weight (23 oz). For birding, the very sharp Panny Leica 100-400 (equivalent 200-800) is only 35 oz. Just an option to look at.
I have a G9 I’m selling because as great a camera as it is for many things the focus is just too slow for wildlife, especially BIF. I switched to an Olympus E-M1X which is huge for a MFT body, bigger than my D500. The E-M1 Mark III does almost as well with focus tracking and is considerably smaller.
