Yes, more bluebirds

I know what you're thinking.  However, Saturday morning, the bluebirds and I had an extraordinary time.

See, I checked the bluebird box last week and they had quite a nest built up inside the box.  I figured I had just missed all the photographic opportunities of them building the nest.  I was pretty bummed about that, because I think those can be some of the best images.  I guess I was living right, or someone knew how bummed I was because Saturday morning, they added a few finishing touches to the nest that allowed me to get some great shots.

ISO 6400, 600mm, F/6.3 @ 1/1250th second

The light was not the best so I knew I was going to be shooting at higher ISOs.  This made me go with the Sony A7R II for my body choice.  I probably ended up missing a lot of shots because it is so much slower than the A77 II I normally use in terms of FPS, but I also might not have gotten these shots at all due to the A77 II not being able to do as well with higher ISOs.  

This was one of my favorite images of the morning.  Blondie is bringing in a little extra padding for the nest.  

I was able to capture this image with my Sony A7R II, LA-EA3 Adapter and Tamron 150-600mm Lens.  I had this setup mounted to my Sirui tripod and PH-20 GImbal Head.  The PH-20 ended up being a vital piece of this setup.  For these in flight shots, I just pre-focused on the area in front of the house, then locked the PH-20 down.  I knew this head wouldn't be slipping.  I knew once I locked it down , it wasn't moving.  So, after I pre-focused and locked the head down, I would just wait for her to come in and fire away.

 Some skill, some good timing and some good luck...
