Meaning
Judging the bird by its song means evaluating what a practitioner can say intelligibly about the Art, rather than trusting a displayed result alone. The image first invites readers to judge Khunrath after understanding his writings and then becomes a general instruction for assessing alleged transmuters.
Use in the book
At p. 155 the author asks to be judged philosophically from his song. He next rejects the claim that everyone who has transmuted must know the matter or be able to prepare the Stone. The intervening account distinguishes possession of tincture from the ability to reproduce it.
Page 157 returns to the bird, asking whether its song is Nature-conforming. “Speak, that I may hear who you are” makes the test explicit, followed by proving spirits against Nature's touchstone. Speech is not accepted merely because it is learned or confident; its agreement with the natural account is what matters.
Unlike the mocking birds elsewhere, this image allows a true philosopher to sing well. It names a discrimination rather than a fixed animal type assigned only to enemies.

Translation in this edition
Keep the song image rather than replacing it entirely with “explanation.” The metaphor's recurrence binds the author's own accountability to the test he demands of others.
Source note
The short Latin demand to speak is printed by Khunrath. No named classical speaker is supplied at this point, so none is invented here.
