External wetting poses problems of immediate heat loss and long-term pathogen growth for vertebrates. Beyond these risks, the locomotor ability of smaller animals, and particularly of fliers, may be impaired by water adhering to the body. Here, we report on the remarkable ability of hummingbirds to perform rapid shakes in order to expel water from their plumage even while in flight. Kinematic performance of aerial versus non-aerial shakes (i.e. those performed while perching) was compared…

Flying in the rain: hovering performance of Anna's hummingbirds under varied precipitation

Remarkably, hummingbirds hovered well even under heavy precipitation with no apparent loss of control, although mechanical power output assuming perfect and zero storage of elastic energy was estimated to be about 9 and 57 per cent higher, respectively, compared with normal hovering.

Into rude air: hummingbird flight performance in variable aerial environments

Recent studies on hummingbirds flying within challenging aerial environments are reviewed, and both the direct and indirect effects of unsteady environmental flows such as rain and von Kármán vortex streets are discussed.

Into turbulent air: size-dependent effects of von Kármán vortex streets on hummingbird flight kinematics and energetics

The findings suggest that vortical flows frequently encountered by aerial taxa in diverse environments may impose substantial energetic costs.

Wet mammals shake at tuned frequencies to dry

The power law relationship between shaking frequency f and body mass M is reported to be close to the authors' prediction of f ∼ M−0.22, which is close to the balance of centrifugal and capillary forces.

Raindrops push and splash flying insects

In their daily lives, flying insects face a gauntlet of environmental challenges, from wind gusts to raindrop impacts. In this combined experimental and theoretical study, we use high-speed

Automatic analysis and characterization of the hummingbird wings motion using dense optical flow features

A new method for automatic analysis and characterization of recorded hummingbird wing motion is proposed. The method starts by computing a multiscale dense optical flow field, which is used to

Hydrophobic Antiwetting of Aquatic UAVs: Static and Dynamic Experiment and Simulation

The adhesion of water to the surfaces of unmanned aerial vehicles (UAVs) adversely affects the function. The proposed UAVs will have underwater as well as flight capability, and these aquatic UAVs

Blinking behavior in great‐tailed grackles ( Quiscalus mexicanus ) increases during simulated rainfall

Given high metabolic costs during rainfall in some species, individuals that minimize their behavioral activity during rainy conditions may maximize their energetic tradeoffs.

Biomechanics of the Peacock’s Display: How Feather Structure and Resonance Influence Multimodal Signaling

It is shown that peacocks with longer trains use slightly higher vibration frequencies on average, even though longer train feathers are heavier and have lower resonant frequencies, and proposed hypotheses for future studies of the function and energetics of this display are proposed.

The ecological and evolutionary interface of hummingbird flight physiology.

Comparisons of hummingbird communities across elevational gradients suggest that foraging strategies and competitive interactions within and among species vary systematically across elevations as the costs of flight change with body size and wing shape.

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.

Low speed maneuvering flight of the rose-breasted cockatoo (Eolophus roseicapillus). II. Inertial and aerodynamic reorientation

Properties of both inertial reorientation and aerodynamic torque estimates correlated, significantly, with asymmetries in the activation profile of four flight muscles: the pectoralis, supracoracoideus, biceps brachii and extensor metacarpi radialis, meaning avian flight maneuvers rely on production of asymmetry throughout the flight apparatus rather than in a specific set of control or turning muscles.

WING-SPREADING BEHAVIOUR OF THE CORMORANT Phalacrocorax carbo

This paper describes an investigation into the factors influencing the occurrence and duration of the wing-spreading behaviour of the Cormorant. It was found to occur only after a period in the water

Bird Maneuvering Flight: Blurred Bodies, Clear Heads1

Experiments with pigeons suggest the ability to isolate the visual and Vestibular systems is critical to controlled flapping flight: birds wearing collars that prohibited the neck from isolating the head from the angular accelerations of induced rolls frequently exhibited a loss of vestibular and/or visual horizon and were unable to maintain controlled flight.

Righting and turning in mid-air using appendage inertia: reptile tails, analytical models and bio-inspired robots.

A new three-dimensional analytical model was developed that predicted an increase in body roll and turning as tails increase in length relative to the body and reinforced how effective attitude control can be attained with simple movements of an inertial appendage.

Alcid Feathers Wet on One Side Impede Air Outflow Without Compromising Resistance to Water Penetration

Abstract. While diving, small alcids appear wet, suggesting that their feathers repel water poorly. Nevertheless, once wet, their plumage resists water penetration effectively. This study's objective

Takeoff flight performance and plumage wettability in Cassin’s Auklet Ptychoramphus aleuticus, Xantus’s Murrelet Synthliboramphus hypoleucus and Leach’s Storm-petrel Oceanodroma leucorhoa

Examination of takeoff performance both before and after experimentally submerging the birds indicated that wingbeat frequency, speed and mass-specific power (peak and mean), and energy per wingbeat decreased in all species when plumage was experimentally wetted, whereas mean acceleration increased.
