I just got an app on my phone that will identify a bird by its sound. It's from Cornell University and it's free. It's called Merlin. It works. So far I've tried it on birds I knew around the house, Northern Cardinal, Carolina Wren, Carolina Chickadee and Coopers Hawk. This kind of stuff just leaves me shaking my head.
what are the odds that it geotags their (your) location too?
gotta be free for a reason...
