Thanks all. They are highly entertaining to watch as they get ready for nesting. When the light is right, it is fun to walk across the road and watch them for a while. I will post a couple of low quality funny shots in a new thread.
Regarding speeds. These are mostly at 1/1000 or 1/1250 second at ISO 400 and 640...we had some high haze for a while that cut down the light intensity so the ISO was boosted a bit.
FYI...some may not know this....on sunny days when you really need fast speeds, boost the ISO ... in good light you will not see any noise at ISOs of 640 and 800..even to 1600 if the light is good. This is not something you want to do as a rule, but you can get away with it now and then. Micro noise can be better than blur in some instances.
Cheers!
