I for the life of me have trouble identifying the tuning used in this song. I tried open D, open D modal, open G, open G modal with no luck. If someone can at least identify the tuning used in this video that'd be great. And even better if someone could identify the chords used in this song. It's a very chirpy tune and I'd love to be able to play it at my own leisure.

Thanks!!!
