I think this little bird has a nest atop the corner bricks of our house, in a tiny space between the bricks and the eaves.
Here's what the Cornell Lab of Ornithology has to say: "One of our most familiar eastern flycatchers, the Eastern Phoebe’s raspy “phoebe” call is a frequent sound around yards and farms in spring and summer. These brown-and-white songbirds sit upright and wag their tails from prominent, low perches. They typically place their mud-and-grass nests in protected nooks on bridges, barns, and houses, which adds to the species’ familiarity to humans."
