I found a fascinating article about how more diversity of birdsongs leads to improved mood, so I wrote a post about it.
This is so interesting, and I believe it! Hearing birds is always such a comfort to me, but I had not considered the diversity aspect. Will read your post for sure! I have a few woodsy parks near me where I love to go because I hear lots of birds, and I need to make time to do this more often.

I have added you! And thanks for the community recommendation, I will check that out as well.
