Scientists have been continuously documenting their findings when it comes to a crescent pigeon giving off what they feel is an alarm. They found that even when the wings are altered, the specific sound that the bird gives off during these times gives the other pigeons warning. No matter where they are, once the flock of pigeons hears this sound, they all flee away as if it were a warning of apparent danger up ahead.
Key Takeaways:
- For a long time, scientists did not know whether the sounds produced by bird feathers were a form of communicating or not
- After conducting some experimentation, scientists have now concluded that there is intentional communication going on associated with the sounds
- Scientists discovered that the birds produce a noise with higher pitch than normal to alert one another to the presence of danger
“When the crested pigeon of Australia flees potential foes, it can raise an alarm — not by calling out vocally, but with whistling feathers in its wings.”
