Cliff swallows (Petrochelidon pyrrhonota) are highly maneuverable social birds that often forage and fly in large open spaces. Here we used multi-camera videography to measure the three-dimensional kinematics of their natural flight maneuvers in the field. Specifically, we collected data on tandem flights, defined as two birds maneuvering together. These data permit us to evaluate several hypotheses on the high-speed maneuvering flight performance of birds. We found that high-speed turns are…

Gliding for a free lunch: biomechanics of foraging flight in common swifts (Apus apus)
Foraging common swifts spend the majority of their time gliding while making use of environmental energy such as thermals and gusts which, on average, completely cover the cost of flight.
Field Flight Dynamics of Hummingbirds during Territory Encroachment and Defense
Although birds departing from the feeder while chased did so faster than freely-departing birds, these speed gains were accomplished by modulating kinetic and potential energy gains rather than increasing overall power output, essentially trading altitude for speed during their evasive maneuver.
Hummingbird maneuvering performance : aerodynamic mechanisms and physiological constraints
The results indicate that hummingbirds have wings that operate with a high degree of independence and that this feature influences their precision and control.
Foraging at the edge of the world: low-altitude, high-speed manoeuvering in barn swallows
While prior studies of swallow manoeuvering have focused on slow-speed flight and obstacle avoidance in still air, swallows survive by foraging at high speeds in windy environments. Recent advances
Field swimming behavior in largemouth bass deviates from predictions based on economy and propulsive efficiency
Video analysis of largemouth bass swimming behavior in the field suggests that they do not use swimming speeds or propulsive movements that maximize economy and efficiency.
Collective turns in jackdaw flocks: kinematics and information transfer
The kinematics of flocks of wild jackdaws executing collective turns in two contexts: during transit to roosts and anti-predator mobbing are measured and it is found that as the group size increased the information transfer speed initially increased, but rapidly saturated to a constant value.
Burst muscle performance predicts the speed, acceleration, and turning performance of Anna’s hummingbirds
An automated tracking system used to record flight sequences from 20 Anna's hummingbirds flying solo and in competition in a large chamber to indicate that burst muscle capacity is a key predictor of maneuverability.
Covering Ground: Movement Patterns and Random Walk Behavior in Aquilonastra anomala Sea Stars
Time-lapse photography is used to track movements of a small, hardy, and easy-to-obtain organism, Aquilonastra anomala sea stars, to suggest that comparing the effectiveness of an organism’s paths to those from theory can give insight into the organism's actual movement strategy.
High speed visual insect swarm tracker (Hi-VISTA) used to identify the effects of confinement on individual insect flight
Individual insects flying in crowded assemblies perform complex aerial maneuvers by sensing and feeding back neighbor measurements to small changes in their wing motions. To understand the individual


Kinematics of slow turn maneuvering in the fruit bat Cynopterus brachyotis
The kinematics of slow-speed turning flight in the lesser short-nosed fruit bat, Cynopterus brachyotis, are examined to understand the basic mechanics employed to perform maneuvers and to compare them with previous findings in bats and other flying organisms.

An 'adverse-scaling' hypothesis is proposed in which it is proposed that the ability to reduce metabolic and mechanical power output using flap-bounding flight at fast flight speeds is scaled negatively with body mass.
Low speed maneuvering flight of the rose-breasted cockatoo (Eolophus roseicapillus). I. Kinematic and neuromuscular control of turning
Examination of the kinematics and neuromuscular control of turning flight in the rose-breasted cockatoo Eolophus roseicapillus finds changes in roll angle were found to include both within-wingbeat and among-Wingbeat components that bear no direct relationship to one another.
Asymmetrical Force Production in the Maneuvering Flight of Pigeons
Downstroke force produced by Rock Doves (Columba livia) as they negotiated an obstacle course was measured using in vivo recordings of delto-pectoral crest strain, suggesting that the birds maneuvered in a saltatory manner during slow flight.
Flight kinematics of the barn swallow (Hirundo rustica) over a wide range of speeds in a wind tunnel.
Results from this study indicate the high plasticity in the wingbeat kinematics and use of the tail that birds have available to them in order to adjust the lift and power output required for flight.

It is concluded that Poedlobothrus pursuit is basically continuous in nature, but it is argued that the two types of mechanism are hard to distinguish in natural behaviour.
Pigeons steer like helicopters and generate down- and upstroke lift during low speed turns
This work examined net aerodynamic forces and body orientations in slowly flying pigeons (Columba livia) executing level 90° turns and found that pigeons achieve low speed turns much like helicopters, by using whole-body rotations to alter the direction of aerodynamic force production to change their flight trajectory.
Courtship dives of Anna's hummingbird offer insights into flight performance limits
Diving male Anna's hummingbirds were filmed with a combination of high-speed and conventional video cameras and experienced centripetal accelerations nearly nine times greater than gravitational acceleration, the highest reported for any vertebrate undergoing a voluntary aerial manoeuvre, except jet fighter pilots.

It is vital to test the metabolic costs of intermittent flight to understand why some birds use intermittent bounds during slow flight, and experimental designs of maneuvering and stability should measure inertial and aerodynamic forces.
Wind tunnel studies of turns by flying dragonflies.
High-speed movies of dragonflies turning in flight on flexible tethers show that there are two distinct modes of turning, including the 'yaw turn', which may be hampered by drag on the abdomen during fast forward flight and would be most useful at low speeds or during hovering.
