This video was taken by Jennie (Veery) and we are unsure of what it is. Unfortunately, Google messed up the footage a bit, but the sound is there. Let us know what you think! (Video taken in northern Illinois, April 5th)
UPDATE: The video is not the greatest quality, but the song playing at the very beginning is coming from the bird. We made a still shot from the video to show a better view. We think it is a Rusty Blackbird (based mostly on sound) but there has been some debate so we are unsure.
