Bluebirds are wild and somewhat uncommon thanks to invasive House Sparrows and European Starlings competing for nesting holes. I've never heard of one as a pet but I have heard of "Bluebird Trails" where competing species are manually evicted from birdhouses spaced far enough apart to avoid territorial disputes.
