Falcon wearing an actioncam takes down a crow after an aerial persuit
Here's an incredible POV of falcons hunting crows. This footage was used to study how predators track and capture their prey. By tracking a combination of things including sensory perception, neural computation and locomotion, the researchers now have a better understanding of what is involved in pursuit of preys. Here's the abstract:
This study reports on experiments on falcons wearing miniature videocameras mounted on their backs or heads while pursuing flying prey. Videos of hunts by a gyrfalcon (Falco rusticolus), gyrfalcon (F. rusticolus)/Saker falcon (F. cherrug) hybrids and peregrine falcons (F. peregrinus) were analyzed to determine apparent prey positions on their visual fields during pursuits. These video data were then interpreted using computer simulations of pursuit steering laws observed in insects and mammals. A comparison of the empirical and modeling data indicates that falcons use cues due to the apparent motion of prey on the falcon's visual field to track and capture flying prey via a form of motion camouflage. The falcons also were found to maintain their prey's image at visual angles consistent with using their shallow fovea. These results should prove relevant for understanding the co-evolution of pursuit and evasion, as well as the development of computer models of predation and the integration of sensory and locomotion systems in biomimetic robots.

In fact, the number of biologists who have expressed some degree of disillusionment is practically endless."

Zzzz
DeleteEvolution pwns the sh*t out of you.
2:46, congratulations, your comment is proof of devolution. But cheer up, that's a good job writing, for a lower-order ape. Now you can get back to grunting and snorting and farting all over your front lawn.
DeleteHooray!
DeleteYes...science bad...stay away from the hospital
DeleteHellz yea.I get sick I just drink rum.And lots of it.
DeleteGod's good gift..plus I have excellent health coverage
DeleteModeration...always
Delete3:07 the resident butthurt footer and poster boy for stupidity that was identified on the previous thread is now denying evolution.
DeleteWhat a deluded moron he is.
I'm thinking that's Leon
DeleteNa its the packham obsessive from the previous thread. Can spot him a mile off. Always butthurt to f*ck.
Deleteso u wanna butthurt to f* ck?wow u crazy
Delete3:52 wow you really are stupid in the extreme..there are so many scientists (those fella`s you revere so much) that have turned AWAY from the unfounded belief of "evolution"..it really is astonishing just how Darwin himself stated the his theory would ONLY be proven by future evidence..this has not been forthcoming in more that 100 years of research..in fact the opposite is true..the more geneticists research,the more it is shown that the theory of evolution is just a spent idea..the people involved in this research actually KNOW what they are speaking of..you do NOT..and if you bothered to investigate you would find that these scientists are at the very top of their professions..and guess what ? ...NOT ONE PIECE of corroborating evidence to support the theory of evolution has come to light..even the much quoted Darwin`s Finches has been shown to be a false interpretation..but here IS a truth..YOU are a FOOL.

Deletego on..watch it...you mind-blinded fool
That Captain America is a star spangled fool...cosmic cube evolved man into bigfoot
DeleteLong Live the Falcon Project! Long Live the Skookum Cast!
ReplyDeleteLONG LIVE MUCKLEGRUNT!!!
DeleteLONG LIVE POOP IN A JAR GUY!!!
LONG LIVE ANONY!!!
LONG LIVE BIGFOOT EVIDENCE!!!
LONG LIVE ROCK ANDROID ROLL...LONG LIVE RUSH...LONG LIVE NOLAN
DeleteOh for God's sake
Deletefricken autocorrect
DeleteLONG LIVE THE QUEEN! ELTON JOHN FOREVER!
Deletethats pushing it bub^^....maybe triumph and the stooges
DeleteWonder what got this guy so butthurt lately? ^
ReplyDeleteWas bigfoot on Noah's ark?
ReplyDeleteAnd did he wear a furry diaper?
Stowaway.
DeleteIf you would remove the soiled diaper from your head, you would be surprised at the improvement in your vision and motor skills. Try it, then write another comment.
DeleteNoah was Bigfoot.
DeleteThinks out of the box.I like it!
DeleteBlow me zit
DeleteSeven of each kind of that is clean to eat. Two of the unclean.
DeleteGenus is 7:2
My old minister preached this and it makes sense for genetic diversity
MMC
3:04 ..the "animals" that went into the ark two by two were dna samples contained in phials..bigfoot was in genetic code inside a test-toob.
DeleteGideon ' s Bible?
ReplyDeleteHahahahaha!
ReplyDeleteo gosh. what has bigfoot become now. that falcon vid is a fake. its not burry enough either.
ReplyDeleteo the humanity...
And I thought that I had a tough commute.
ReplyDeleteThe resident butthurt footer and poster boy for footer stupidity has woken up in a cold sweat after having another nightmare about packham phoning up gimlin.
ReplyDeletePackham: successful naturalist and TV presenter. Currently presents a BBC prime time nature show that pull in millions of viewers.
ReplyDeleteThe resident butthurt footer and poster boy for footer stupidity: a deluded nobody who's proudest achievement is his post count on the bff.
Packham doesn't talk about bigfoot. Ask mmg.
DeleteGo team fruity
ReplyDeleteBBC doesn't have millions of viewers...Mr. Bean maybe
ReplyDeletePooperfriends!
ReplyDelete^ so that's what it's called now
Deletenah,ya jackass
DeleteSome of the most compelling video I have ever seen as a scientist. Yet 38 comments none on subject. What a stupid group of people
ReplyDeleteu so smart wanna b my friend?
Delete^^ instead of negative commenting why not attempt to begin the dialogue yourself...it really is beholden upon YOU to instigate something you wish to partake of/in ..it is that simple,Mr Scientist..or did you need evidence on a lab slide to fathom that essential truth ?
DeleteIt's just a hawk video
Deletehow'd I get here ?
