Eastern Phoebe nest in the rafters of our barn. The sheet metal acts as a baffle to prevent the Red Squirrel from reaching the nest.
We just saw the first Eastern Phoebe arrive on our property. Perhaps this is the same phoebe, that has nested in the same spot, in our bard for at least the last 4 years, (it's always amazing when that happens), we hope so. The barn doors are open for it. The nesting spot is surrounded by a several pieces of sheet metal, put up several years ago, which prevents the naughty Red Squirrel from eating the eggs out of the nest, as it once did.
That's what I like about spring, the anticipation of all the new stories, about each and every species that nests on our property, that will unfold as the season progresses.
