A Virginia Rail (Rallus limicola) adult lifts an invertebrate out of the muck prior to feeding it to one of two chicks. This was taken from the auto tour route at Montezuma NWR near Seneca Falls, New York on June 22, 2007.

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.
A solo adult, recorded from 6 feet away. He did this, as I've often heard them do, for a solid 15 minutes, while staying in one spot. If you hear them doing this, they'll usually continue for some time.
This is a very sexy sound if you're a Virginia Rail in the Springtime. It means "I'm ready, and I'm lookin' for love!" It's generally called the "ti-dick" sound. The double clicks ("ti-dick") are diagnostic of the Virginia Rail. King and Clapper Rails also click, but generally not in "doublets".
