Interesting Fact: The male Eastern Bluebird displays at his nest cavity to attract a female. He brings nest material to the hole, goes in and out, and waves his wings while perched above it. That is pretty much his contribution to nest building; only the female Eastern Bluebird builds the nest and incubates the eggs. ( https://www.allaboutbirds.org/guide/Eastern_Bluebird/lifehistory )
