This Rashi seems difficult to understand. The chirping of the birds doesn’t seem to fit into the equation. If you listen to the sounds of birds chirping on a spring day, you’ll hear an unending stream of sound, much like turning on the faucet in your kitchen sink. The flow begins, short chirps and long chirps forming some type of pattern, but it’s without thought; the birds just jabber away.
What connection does that have with intelligent speech? Speech isn’t merely the formation of sounds; speech is the highest form of communication, a power given to man alone to share his inner thoughts and understandings. Each word or phrase can represent entire concepts and ideas. Man alone can relay a world of understanding in but a few expressions. In what way can that be compared to the chattering of birds, a mindless, thoughtless, automatic reflex?
