Black-throated Blues are the quintessential Blue Ridge Parkway warbler for North Carolina. This is one of the handful of warblers that can be found summering in NC. They can be found at lower and higher elevations and their buzzing song can be heard even by half deaf birders like me. I captured the below picture on the Commissary Ridge Trail just down from the Mount Mitchell summit, the highest point east of the Mississippi River. Now I just need to get a picture of Black-throated Green eating green grapes.
