A new low-turbulence wind tunnel for animal and small vehicle flight experiments [PDF]
Our understanding of animal flight benefits greatly from specialized wind tunnels designed for flying animals. Existing facilities can simulate laminar flow during straight, ascending and descending flight, as well as at different altitudes. However, the

Dynamic echo information guides flight in the big brown bat
Animals rely on sensory feedback from their environment to guide locomotion. For instance, visually guided animals use patterns of optic flow to control their velocity and to estimate their distance to objects (e.g. Srinivasan et al. 1991, 1996). In this

The mouse ventromedial hypothalamus (VMH) is both necessary and sufficient for defensive responses to predator and social threats. Defensive behaviors typically involve cautious approach toward potentially threatening stimuli aimed at obtaining ...

Realistic modeling of bird flight animations [PDF]
In this paper we describe a physics-based method for synthesis of bird flight animations. Our method computes a realistic set of wingbeats that enables a bird to follow the specified trajectory. We model the bird as an articulated skeleton with elastically deformable feathers.

The Critical Role of Head Movements for Spatial Representation During Bumblebees Learning Flight
Bumblebees perform complex flight maneuvers around the barely visible entrance of their nest upon their first departures. During these flights bees learn visual information about the surroundings, possibly including its spatial layout.

Flight Zone as an Alternative Temperament Assessment to Predict Animal Efficiency
Animal temperament evaluation can be included in the cattle selection program also because of an existing correlation with performance. However, there are different assessment methods such as flight speed (time and speed that an animal takes to leave the

Wolf Responses to Experimental Human Approaches Using High-Resolution Positioning Data
Humans pose a major mortality risk to wolves. Hence, similar to how prey respond to predators, wolves can be expected to show anti-predator responses to humans. When exposed to a threat, animals may show a fight, flight, freeze or hide response. The type

Aeroecology is an emerging discipline founded by Tom Kunz and colleagues in the early 2000s to address the challenges of studying animal flight in the lower atmosphere [...]

North American Animated Flight Atlas
Abstract There are many different landscapes. The landscape mapped here forms in the sky as thousands of aircraft are carefully choreographed by ground control to ferry passengers from one place to another. It is this landscape of constantly moving air traffic that is the subject of a new atlas.

Limitations on Animal Flight Performance [PDF]
ABSTRACT Flight performance seems to change systematically with body size: small animals can hover and fly over a wide range of speeds, but large birds taxi for takeoff and then fly over a narrow speed range. The traditional explanation for this is that the mass-specific power required for flight varies with speed according to a U-shaped
