Falcons pursue prey using visual motion cues: new perspectives from animal-borne cameras

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.

The First Hundred Years Of Photography

A fascinating film from 1939 that looks back at the first hundred years of photography.

“Have we made progress? The answer’s in the negative. That’s positive!” ~ Vic_Wailuku

In 1939, British Pathé — whose fascinating photography-related old videos we’ve shared before — covered something truly amazing: 100 years of photography. It had been 100 years since the camera was invented and so, they took a look back at how those years had changed and refined the art of capturing images using a light-tight box and whatever light-sensitive material you happen to have at hand.

The video really does earn the term ‘fascinating,’ but beyond condensing some great educational tidbits into just a couple of minutes, it also makes you wonder at what 2036′s look back will show. There are already so many wonders we have to celebrate at the 175-year mark, how many more do the next 25 years hold?

Eagle Steals Camera

Mason Colby was filming eagles eating salmon with his GoPro camera when one of them swooped down, grabbed the camera and flew away it.

Set up my go pro next to some salmon heads from the days catch to film the eagles eating and next thing I know, one of them swoops down and snags the camera right off the ground. It carried it up to a mile away and I lost sight of it. For four hours we searched in the rain until I finally found it and the camera was still intact. So glad I got the footage!
