Thanks for the pointers Jeff.

I did get some shots that (I think) are good. It was the consistency that was unsettling me. The light was changing due to fast moving clouds. The birds were obviously all over the place in the breeze! So I made the decision to bracket exposure. 

The problem was that in addition to the birds attitude changing between frames ( why does the best body shape happen on the underexposed frame? 😡) the camera wasn't keeping up with the undulating circulatory flight of the bird. It was this problem that most spooked me. 

The focus locked on for the first shot but despite keeping the 9spot focus frame on the bird, the focus didnt follow the bird. It could have been the lack of contrast on the bird itself ( brown on brown) exacerbated by the shadow effect from backlighting ( when inadequate ex comp applied). Or it could have been the communication failure of the teleconverter?? It wasn't the camera persay, as I tried 2 bodies and got the same lethargic AFC with each. The focus responded normally when focusing on subjects beyond 30m but at 20m the focus just seemed to 'stick'.

I ran out of time and weather to do more meaningful tests but I think I will take your advice and ditch the Teleconverter as a first action for bif exercises for the time being. 

One of my better ones....
