A Lesson In Life

Mr. Turtle was walking down the road when he spotted a crow at the tip top of a very tall tree. He shouted, “Good Morning, Mr. Crow.”Mr. Crow shouted back down, “Good Morning, Mr. Turtle.”

Mr. Turtle was walking down the road when he spotted a crow at the tip top of a very tall tree. He shouted, “Good Morning, Mr. Crow.”

Mr. Crow shouted back down, “Good Morning, Mr. Turtle.”

Mr. Turtle shouted up, “Whatcha doin’ today?” and the answer shouted back down was,

“Absolutely nothin’ Mr. Turtle – Absolutely nothin’ and loving it.”

Well, that sounded pretty good to Mr. Turtle, so he shouted back up, “Do you think I could do that too?”

Mr. Crow shouted back down, “I don’t see why not!”

So, Mr. Turtle lay down on the side of the road and began Doing Absolutely Nothing.

In 30 minutes a fox came along and ate him.

The moral of the story is: You can get away with Doing Absolutely Nothing, but only if you are really high up.

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.
