“Tree Swallows” are small songbirds with long, pointed wings and a short, squared or slightly notched tail. Their bills are very short and flat. They nest in holes of exactly the same size and have taken advantage of bluebird houses over much of North America. We’ve been inspired by these chatty birds with a blend of wild oranges, yuzu, bergamot, red cedar, fir needles, thyme, musk and sandalwood.
