The evolution of avian flight remains one of biology’s major controversies, with a long history of functional interpretations of fossil forms given as evidence for either an arboreal or cursorial origin of flight. Despite repeated emphasis on the ‘wing-stroke’ as a necessary avenue of investigation for addressing the evolution of flight, no empirical data exist on wing-stroke dynamics in an experimental evolutionary context. Here we present the first comparison of wing-stroke kinematics of the… Expand

TLDR
To improve understanding of the functional significance of flap-bounding, the energetic costs and the relative use of alternative styles by a given species in nature merit study. Expand
New Perspectives on the Ontogeny and Evolution of Avian Locomotion.
TLDR
The ontogeny of avian locomotion is reviewed, highlighting how the developmental acquisition of flight in extant birds can improve the authors' understanding of form-function relationships in the avian body plan, and provide insight into the evolutionary origin of flight among extinct non-avian theropod dinosaurs. Expand
The wings before the bird: an evaluation of flapping-based locomotory hypotheses in bird antecedents
TLDR
It is found that “near flight” locomotor behaviors are most sensitive to wing area, and that non-locomotory related selection regimes likely expanded wing area well before WAIR and other such behaviors were possible in derived avians. Expand

TLDR
Calculations indicated that even moderate wing movements are enough to generate rudimentary thrust and that a propulsive flapping flight-stroke could have evolved via gradual incremental changes in wing movement and wing morphology. Expand
The broad range of contractile behaviour of the avian pectoralis: functional and evolutionary implications
TLDR
It is concluded that WAIR remains a useful extant model for the evolutionary transition from terrestrial to aerial locomotion in birds because work and power requirements from the pectoralis increase incrementally during WAIR and from WAIR to flight. Expand
Evolution of Avian Flight
TLDR
A growing number of researchers have suggested that hypotheses must be consistent not only with the fossil record, but also with experimental support for form–function relationships and behaviours inferred by origin-of-flight scenarios. Expand
Flight of Mammals: From Terrestrial Limbs to Wings
The evolutionary acquisition of flapping flight in mammals remains one of the unresolved questions of biology. Currently, no consensus as to the morphofunctional steps through which mammals passed toExpand
Multiple Functional Solutions During Flightless to Flight-Capable Transitions
The evolution of avian flight is one of the great transformations in vertebrate history, marked by striking anatomical changes that presumably help meet the demands of aerial locomotion. TheseExpand
The biophysics of bird flight: functional relationships integrate aerodynamics, morphology, kinematics, muscles and sensors
TLDR
Research at the interface of the systems used in flight control is reviewed and several common themes are discussed, including wing velocity about the shoulder, shape within the wing, and angle of attack. Expand

The origin of the avian flight stroke: a kinematic and kinetic perspective
TLDR
This work introduces six kinetic components that interact to determine a limb's trajectory and offers four specific criteria to help constrain and evaluate competing scenarios for the origin of the avian flight stroke. Expand
What Use Is Half a Wing in the Ecology and Evolution of Birds?
TLDR
It is argued that avian ancestors may have used WAIR as an evolutionary transition from bipedal locomotion to flapping flight, a recently described locomotor mode in which fully or even partially developed flapping forelimbs are recruited to increase hindlimb traction and escape performance. Expand

  • K. Dial

TLDR
WAIR provides insight from behaviors observable in living birds into the possible role of incipient wings in feathered theropod dinosaurs and offers a previously unstudied explanation for the evolution of avian flight. Expand
Aerodynamics of wing-assisted incline running in birds
TLDR
The results reveal for the first time that lift from the wings, rather than wing inertia or profile drag, is primarily responsible for accelerating the body toward the substrate during WAIR, and that partially developed wings, not yet capable of flight, can produce useful lift duringWAIR. Expand

TLDR
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. Expand
On the origins of birds: the sequence of character acquisition in the evolution of avian flight

TLDR
Viewing upstroke as more than stereotypical, symmetrical wing recovery alters the evolutionary and functional context of investigations into the musculoskeletal mechanisms and the associated neural control involved in this unique kinematic event. Expand
Some hypothetical anatomical stages in the evolution of avian flight
TLDR
I would suggest that the reason Confuciusornis is the most abundant bird in the deposit is because flocks of them were flying over the lake when disaster struck, and the presence of many individuals in a single layer over a small area of lake deposit suggests colonial behavior and a catastrophic dieoff. Expand
Mechanics of wing-assisted incline running (WAIR)
TLDR
Wing function data support the hypothesis that forelimbs are enabling hindlimb function, and argue that WAIR represents a locomotor strategy which may have been used by proto-birds during the evolution of flight. Expand
Estimates of circulation and gait change based on a three-dimensional kinematic analysis of flight in cockatiels (Nymphicus hollandicus) and ringed turtle-doves (Streptopelia risoria).
TLDR
Gait use was investigated via a combination of three-dimensional kinematics and quasi-steady aerodynamic modeling of bound circulation on the distal and proximal portions of the wing and found that the shift from a vortex-ring to a continuous-vortex gait was associated with a phase delay in the peak angle of attack of the proximal wing section from downstroke into upstroke.
