Canon 1DX

Hi , currently im using a 1DX + 500mm f4 is + 1.4 iii extender for my bird photography but im finding with the extender the autofocus takes a bit longer to focus on birds in flight which i knew would be the case with extenders so is there any settings on the 1DX that could be tweaked that would make it any better either turning settings on or off to get quicker focus lock . Many thanks

Purple 2 image priority.. I have this to release in dark conditions..(I don't do brids but my subjects move fast) I pretty much know I have the subject in focus and don't need to wait for the camera to confirm... Its fast in daytime hardly noticable.. but for that nano second difference between getting a shot or not?
