I acquired this kit on-line from the Purple Martin Conservation Association. It feels very solidly built and the gourds have Starling resistant entrance holes. The whole gourd rack lowers using a pulley system in order to do nest checks. I also installed optional owl guards on the top row and a predator baffle on the pole, as I have done on the bluebird houses. The concrete pier is 36" x 12" extending partly above ground. We will make a raised rock landscape feature around the base.
I don't know where to get "pine straw" around here so I filled the gourds with "normal" straw. Since taking the pictures, I have also numbered all of the gourds for record keeping.
On day two of dawn song playing, I found two Starlings sitting on the upper perch rods ... sigh, another species to control.
The story continues on another post with the arrival of my first pair.
