That's wonderful! I have put several bird houses out and never once have any birds nested in them. The jays prefer building in low tree branches with dense shrubs nearby for the babies to hide in when they leave the nest. House finches will build nests in hanging strawberry baskets on the patio, but never once have I seen any bird pay a bit of attention to my bird houses. :-(
I was told and (thats my only proof) that the little Eastern bluebirds will not build in anything but a ‘bluebird’ house! I am worried....didn’t see them yesterday! The people two houses down have a cat and my next door neighbor said the cat stays out there close to my birdhouse. I asked her to chase it off and she said she does everytime she sees it! She loves to watch the bluebirds too! Oh, well, I’ll be out working today and I will keep my eyes open!
