There were several of these towhees scratching in the dirt around the headquarters of the Salton Sea National Wildlife Refuge. These unassuming ground foragers are a characteristic species of the Sonoran Desert. They remain paired for life. The song is given only by unmated males and is seldom heard. Males and females look alike.
