How a Hummingbird Flies in the Wind | ScienceTake | The New York Times

  • 0:07 - 0:08
    (Gentle music plays)
    Hummingbirds are great.
  • 0:08 - 0:09
    They're beautiful,
  • 0:09 - 0:11
    they're fast
    and when they hover,
  • 0:11 - 0:12
    it almost seems
    like magic.
  • 0:13 - 0:16
    But how do they do
    when the wind gets gusty?
  • 0:16 - 0:17
    That's what Australian
  • 0:17 - 0:19
    and American scientists
    wanted to find out
  • 0:19 - 0:21
    when they put the four
    Ruby-throated
  • 0:21 - 0:22
    Hummingbirds
    in a wind tunnel.
  • 0:22 - 0:23
    And the answer is,
  • 0:23 - 0:24
    they just do great.
  • 0:25 - 0:30
    The birds did just fine
    in a steady wind, no surprise there.
  • 0:30 - 0:32
    They also did great
    with the wind speed
  • 0:32 - 0:34
    varying
    by as much as 15%.
  • 0:34 - 0:35
    Just to compare,
  • 0:35 - 0:38
    small drones
    can only handle 7%.
  • 0:38 - 0:39
    One way the birds cope
  • 0:39 - 0:41
    is that they change
    the angle and action
  • 0:41 - 0:43
    of each wing
    independently,
  • 0:43 - 0:45
    in the space
    of a wing beat.
  • 0:45 - 0:48
    Those wings are beating
    40 times per second.
  • 0:49 - 0:51
    And constant
    adjustment of the tail
  • 0:51 - 0:53
    is very important,
  • 0:53 - 0:54
    both in its position
  • 0:54 - 0:56
    and in how much
    it was fanned out.
  • 0:56 - 0:59
    The next step the researchers
    have in mind,
  • 0:59 - 1:00
    is to try to help
  • 1:00 - 1:03
    the drones catch up,
    by giving them tails.
