While birding at Harris Lake Park in New Hill North Carolina, I encountered a familiar song echoing in the woods. It took a bit of walking to reach the source of the noise, but eventually I found this Carolina Wren perched on a brush pile. He paid little attention to my presence as he called out to his unseen mate in the grassy clearing.
Boasting one of the loudest songs per volume among all birds, the male cycles among several dozen song variations. According to the Cornell Lab of Ornithology, one Carolina wren sang nearly 3,000 times in a single day.

But how can a bird like a Carolina Wren, measuring just 5½ inches long and weighing only as much as a few coins , produce so much sound? 
I found the answer via BirdNote.com… “Apparently their unique ability to belt out the loud notes lies in the songbird’s vocal anatomy. Unlike the human voice, which comes from the larynx way up at the top of the windpipe, a bird’s song comes from deep within its body.
Birds produce song in a structure called the syrinx, located at the bottom of the windpipe where the bronchial tubes diverge to the lungs. The syrinx is surrounded by an air sac, and the combination works like a resonating chamber to maintain or amplify sound. 
Evolution has given birds a far more elaborate sound mechanism than it’s given humans. Where we wound up with a flute, songbirds got bagpipes.”

This noisy little one is still a joy to see up close, just remember to bring your earplugs lol!
