Many species of hummingbird produce distinctive sounds with their tail-feathers, which flutter in airflow. Here, I show some of their displays along with the sounds they make. I tested hummingbird tail-feathers in a wind tunnel to determine how the sounds are made. This video shows the results of the study, and includes animations and high-speed videos of feathers in a wind tunnel. Photos courtesy Anand Varma, www.varmaphoto.com

  • Wait a second where did he get all these feathers from?

  • @azNephi over the past several years I have personally worked with all of these species in the field. So, the feathers are from my field work. Hummingbirds are protected by law; in order to do my research, I apply for research permits from government agencies, such as the US Fish & Wildlife Service (for species in the US)

  • amazing!

  • I really like this video. Few very good information on Hummingbirds.

  • did you hurt those birds??? Also: I hear hummers vocalizing while sitting on branches; that must be voice

  • Thank you very much for this presentation! I've been observing hummers for years and years, and always recognized the sounds that were coming from feather vibration during the mating displays- and thanks to you, all my questions are answered! Really- brilliant research, and presentation... Thanks again!!

  • thank you chris for the unnecessary but yet very interesting information

  • amazing

  • That is really cool. I don't recall ever seeing an explanation HOW the tail feathers make the sounds. Sort of chops the air like an old mechanical siren.

  • wow, that is beautiful ~ very interesting sonic study ~ intriguing
