Update,

Built the bases at home. I did use 4 x4's instead of 2 x 4 or 2 x 6 . All pressure treated with galvanized lag bolts and washers, 1/2" dia.

Excavated the two holes, 40" deep . I have them set in the hole, now need to set in the Quickcrete , level and backfill. If I need to counter weight the top hinged section I can deal with that after I have them installed with the nesting box/bat house.

I ended up using all-thread for the two top bolts that will allow me to pivot the 12 foot 4 x 4 down and up. Jam nuts and washers so I can adjust the tension versus carriage bolts.

I feel pretty good about the base build and the depth. The total height from ground level to top of the 4 x4 will be just shy of 14 foot. I was required to have them a minimum of 12ft.

I am under a deadline to get these things in the ground and set up with the nesting box and the bat box. After that I can deal with some details like cutting the tops of the two base 4 x4s at a slight angle to shed water. I also will install a "stop" so the top 4 x 4 and only hinge one way.

I do appreciate the suggestions and did incorporate a few into the build thus far! Thank!

Getting closer to getting this project over the finish line.

240 Lbs of Sakrete in each hole, leveled the bases and backfilled.
I should be able to get the top 12 ft pole with nesting boxes installed by this coming weekend.

I had to modify the opening of the wood duck box to work for Kestrels. The opening is oval shaped and larger than what is required for kestrels. They like a 3" round opening. The rest of the box is the same.
