One couple arrived at the residence. They hoped to find a perfect place to raise a family. It wasn't to be. Another couple had been quicker. They were there earlier and, so, they got first pick on available housing.
The lucky couple's kind was abundant in this country. They'd been brought here for a purpose. They'd fulfilled their purpose. They just wanted to live happily. As did the couple watching them consider this new home. It was freshly cleaned. It fit their needs. The house sparrows moved in, of course.
The eastern bluebird couple flew away, still birdhouse hunting.
