Hillyho! ... wellsir ... I bought three bluebird houses from Lowes. I put a pvc 2" connector over the hole to keep out the larger birds and I heard the bluebirds like that tunnel effect. I put them out almost 2 weeks ago.
I have them pointed east on a metal pole. The house is about 6ft on the pole. I have a baffle on the pole. In one of the houses a bird started constructing a nest, but I have seen no sign of further nest building a couple of days later.
What would cause the bird to stop building.
