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.

  1. "Throughout the past century there has always existed a significant minority of first-rate biologists who have never been able to bring themselves to accept the validity of Darwinian claims. In fact, the number of biologists who have expressed some degree of disillusionment is practically endless."

    9. 3:52 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.

    1. If 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.

    4. 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.

    2. ^^ 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 ?
