Is it true that homing pigeons send messages anonymously?

It's really an anonymous message. Pigeon is a message push service, which will be sent to the other party in the form of anonymous short messages, and the other party can't reply directly. It will be communicated by SMS, and the other party will reply. The message pigeon will inform me like this, and the message I sent in a whisper is enough, so the message is really anonymous.
