Bat flight generates complex aerodynamic tracks
... growing body of data about bat flight. "Bats are agile hunters, capable of plotting and executing complex maneuvers through cluttered environments," he said.

...hreat presented by the potential predator. Small, agile raptors such as the pygmy owl which can prey on small songbirds present a greater danger to the chickadees than does the great horned owl, a larger, less maneuverable raptor. Chickadees and nuthatches are similar in size, occupy many of the same hab...Novel salamander robot crawls its way up the evolutionary ladder
...n relevant for all four-legged organisms of how agile locomotion is controlled by distributed neural mechanisms located in the spinal cord.

...ut in open areas with few trees, the birds must be agile in order to "hover or hop along the ground to search for prey." Despite such advance knowledge about behavior, "the relative importance of behavior in driving or inhibiting evolutionary change remains largely unresolved," Duckworth said.

... smaller raptors represent a greater threat to the agile chickadees than the larger ones because they are more maneuverable in flight and can readily catch small birds. "That's why a pygmy-owl is more dangerous to a chickadee than a great horned owl that has a large hooked beak and big talons.
