“The birds sing blissfully until the joy is so great as to be unbearable: this joy cannot be heard from afar, but if you come near it, you will succumb.” R. Nachman

“The chirping of birds is not just idle song. It is the way that birds praise G-d for providing them with their needs.”
YomTov, Vol. IV # 18. Topic: Shabbos Shira, A Shabbos For the Birds, by Rabbi Yehudah Prero
