Oh dear, you had really lot of troubles with the camera.
So far I am happy with mine as I read the reviews before I decided to buy. Then I joined a group in FB -Nikon Coolpix P900 P950 P1000 P1100 Group. There I saw what photos were posted and I was sure this camera will be OK for birding. I know that there are features that are worse compared to the DSRL, but knowing that beforehand saved me any disappointment. I like the silent shutter and the superzoom. Still can't manage sharp photos of flying birds. This seems to be more difficult.
