Relative Detectability: Easy to detect by its distinctive song, but difficult to confirm nesting. This species has been the focus of nest search efforts in some parts of western Oregon, and those data have been included.

Challenge: Determine if it still nests in northern Wheeler and southwestern Grant Counties.
