Virginia Rails (Rallus limicola) are found nearly everywhere Soras live, and Tavasci Marsh [Arizona] is no exception. These sounds are ones you don't often hear in commercial bird call CDs, but they are the Virginia's common "grunting" calls - they're kind of spooky when you hear them at night for the first time! Listen for the bullfrog during the call.
