Costs of migration, in terms of time, energy, and mortality risk, have a strong theoretical and
empirical foundation in the study of birds. We expect these costs to be most severe for …

It was thought that the aerodynamics of flapping flight in birds is fully understood for quite
some time, but recent studies have shown that this is not the case. Bird flight uses …

The tailless flapping-wing micro air vehicle (FW-MAV) is one of the most challenging
problems in flapping-wing design due to its lack of tail for inherent flight stability. It must be …

This paper provided a design of bat-inspired tailless flapping wing unmanned aerial vehicle
(UAV) based on the biological data of the large flying fox. The wing span of the UAV is 1.68 …

The common swift (Apus apus) is adapted to an aerial lifestyle, where food and nest material
are captured in the air. Observations have prompted scientists to hypothesize that swifts stay …

Being airborne is considered to be energetically more costly as compared with being on the
ground or in water. Birds migrating or foraging while airborne are thought to spend some …

The performance capabilities of flying animals reflect the interplay of biomechanical and
physiological constraints and evolutionary innovation. Of the two extant groups of …

Birds and bats frequently reconfigure their wing planform through a combination of flapping
and local sweep morphing, suggesting a possible approach for improving the performance …

The diversity of flying animals suggests that countless combinations of flight morphologies
and behaviors have evolved with specific lifestyles, thereby exploiting diverse aerodynamic …

Bioinspired Flapping-Wing Micro Aerial Vehicles (FWMAVs) have emerged over the last two
decades as a promising new type of robot. Their high thrustto-weight ratio, versatility, safety …
