II have been admiring the new PVC nest boxes at Crockett Lake, And would like to suggest an improvement. I have 30 years experience with PVC nest boxes, and have found that a coat of flat sand or light brown colored primer helps with standard PVC to preserve it from the effects of the sun.
Another benefit is that it gives the boxes a finished look. When I see the new boxes, I am concerned that someone will think they look too unfinished, and out of place, and they might be upset.
I have the correct paint of the right color, and would be glad to apply it.
With the paint, the boxes will last about 20 years longer. If they were under no stress, then they would last quite a while as is, but the effect of the wind in that location, and torsional stress will crack them off much sooner if the sun is allowed to penetrate.
