Owl in flight
The silent flight of owls has long fascinated ornithologists. No other birds fly with such stealth... First, the leading edge, or primary feathers, on the owls' wings are serrated like a comb. Second, the trailing feathers on the back end of the wing are tattered like the fringe of a scarf. And third, the rest of the owls' wings and legs are covered in velvety down feathers... owls' tattered fringe feathers help to break up the sound waves that are generated as air flows over the top of their wings and forms downstream wakes...
...the silence allows owls to more efficiently use their ears, which are positioned asymmetrically in their skulls: One ear is higher and more forward than the other, and each is shaped slightly different... owls, because of their ears' asymmetry, hear sounds slightly differently through each ear. This allows the raptors to more accurately determine where a sound is coming from.

very. wicked. cool.
ReplyDeleteLooks like a near perfect teardrop shape--sleek!
ReplyDeleteNot particularly aerodynamic though
ReplyDeleteActually it is aerodynamic -

Yeah - it's perfectly aerodynamic.
ReplyDeleteThat is so gorgeous, so amazing. Besides, I love the look of owls.
faint able for a old women
ReplyDeleteit does actually look like a teardrop
ReplyDeletewish I could see it in 3d... what are the wings doing at other viewing angles?
ReplyDeleteWow. Excellent shot.
ReplyDeletetattered fringes? owls just copied that from the 787. i smell a lawsuit.

I wish he could be my friend.
ReplyDeleteAmAzing picture!
ReplyDeleteI'd love to know who took this beautiful photo. Would you post the photographer's name so that we can give proper credit? Thanks!
ReplyDelete@Bill Mowat - a TinEye reverse image search yielded only four hits, including this one -

that claimed "copyright" - but I doubt that's the original source.
my three year old thought this was a fish.
ReplyDeleteGreat pic, very cool.
ReplyDeletealso FYI this blog doesn't render properly in google chrome.
Hi, Do you know who took this shot? thanks..chris
ReplyDelete@ChrisO - I tried to find an original source, but neither the Reddit post or a TinEye reverse image search were any good in that regard.
ReplyDeleteAt this site (http://vi.sualize.us/view/6653c47aebdea9922029134e570c3ccb/) there is a copyright symbol, but it appears to be another photo aggregator, as does the site they link to as "original source."
Perhaps the photographer will find this post and link to the source so I can post the credit.
This is an amazing shot and really interesting fact! I am fascinated by owls.
ReplyDeleteThey don't look perfectly aerodynamic because they have a ring of feathers around their face that offer little air resistance while they direct sound into their ears sort of the way bat ears do. (I know: bats don't have feathers. But they do have weird ears for the same purpose) withouåçt that extending ring of feathers, air pressure there would deflect some faint sounds away sort of like sonar hitting a higher density thermal clime layer.
