We understand little about the energetic costs of flight in free‐ranging birds, in part because current techniques for estimating flight energetics in the wild are limited. Accelerometry is known to estimate energy expenditure through body movement in terrestrial animals, once calibrated using a treadmill with chamber respirometry. The flight equivalent, a wind tunnel with mask respirometry, is particularly difficult to instigate, and has not been applied to calibrate accelerometry. We take the…

Acceleration predicts energy expenditure in a fat, flightless, diving bird

This work combines data from miniaturised acceleration loggers on 58 free-living Adélie penguins with doubly labelled water measurements of their energy expenditure over several days, and provides calibration equations for estimating metabolic rate across several behaviours in the wild.

Overall Dynamic Body Acceleration in Straw-Colored Fruit Bats Increases in Headwinds but Not With Airspeed

Atmospheric conditions impact how animals use the aerosphere, and birds and bats should modify their flight to minimise energetic expenditure relative to changing wind conditions. To investigate how

Dynamic body acceleration increases by 20% during flight ontogeny of greylag geese Anser anser

There was a significant temporal increase of flight duration and ODBA over time, supporting the ‘physical development hypothesis’ and suggesting that early on in flight ontogeny behavioural development leading to flight efficiency plays a weaker role in shaping ODBA changes than the increased physical ability to expend energy in flight.

Coping with the commute: behavioural responses to wind conditions in a foraging seabird

The behaviour during commuting flights of black‐legged kittiwakes Rissa tridactyla breeding on Middleton Island, Alaska is examined and it is demonstrated that the cost of flying into a headwind outweighs the energy saving benefit of flying with a tailwind of equivalent speed.

Optimisation of unsteady flight in learned avian perching manoeuvres

Harris’ hawks Parabuteo unicinctus minimise neither time nor energy when swooping between perches for food, but instead minimise the gap they must close under hazardous post-stall conditions by combining high-speed motion capture with dynamical modelling and numerical optimization.

Optimization of avian perching manoeuvres

Perching at speed is among the most demanding flight behaviours that birds perform1,2 and is beyond the capability of most autonomous vehicles. Smaller birds may touch down by hovering3–8, but larger

Proxy problems: Why a calibration is essential for interpreting quantified changes in energy expenditure from biologging data

1. We do not yet have the means to directly measure the energy expenditure of wild animals, particularly at a high temporal resolution. However, we can instead measure factors that correlate with

Ecological inference using data from accelerometers needs careful protocols

A simple method to calibrate accelerometers that should be used prior to deployments and archived with resulting data is proposed, a way that researchers can assess accuracy in previously collected data is suggested, and caution that variable tag placement and attachment can increase sensor noise and even generate trends that have no biological meaning.

Simulation-based validation of activity logger data for animal behavior studies

Bio-loggers are widely used for studying the movement and behavior of animals. However, some sensors provide more data than is practical to store given experiment or bio-logger design constraints.

This work highlights the key pitfalls associated with analysing physiological data from wild monitoring studies, and investigates issues of optimal study design, statistical power, and model precision and accuracy.



Interpretation of body-mounted accelerometry in flying animals and estimation of biomechanical power

An idealized energy fluctuation model of a bird's body undergoing horizontal flapping flight is developed, focusing on the biomechanical power discernible to a body-mounted accelerometer, offering fresh insights into the processes involved in airborne locomotion.

Recording raptor behavior on the wing via accelerometry

Measuring body movements using accelerometry data loggers is a relatively new technique, the full applicability of which has yet to be tested on volant birds. Our study illustrates the potential of

Backward flight in hummingbirds employs unique kinematic adjustments and entails low metabolic cost

It is proposed that backward flight behavior in retreat from flowers, together with other anatomical, physiological, morphological and behavioral adaptations, enables hummingbirds to maintain strictly aerial nectarivory.

The hypothesis that the power curve may not in fact exist, in the sense that the cost of flight may not be perceived by a bird as a continuous smooth function of air speed, is advanced and is considered together with evidence from variation in flight behaviour, wingbeat kinematics and flight gait with speed.

Assessing the development and application of the accelerometry technique for estimating energy expenditure.

The mechanical power requirements of avian flight

It is shown that in budgerigars and zebra finches power is modulated with flight speed, resulting in U-shaped power–speed relationship, and measured muscle powers agreed well with a range of powers predicted using an aerodynamic model.

Wing inertia and whole-body acceleration: an analysis of instantaneous aerodynamic force production in cockatiels (Nymphicus hollandicus) flying across a range of speeds

Investigating the variation in instantaneous aerodynamic force production during the wingbeat cycle of birds flying across a range of steady speeds found that the inertial power requirements of downstroke were consistent with the assumption that nearly all wing kinetic energy in downstroke was applied to the production of aerodynamic forces and therefore should not be added separately to the overall power cost of flight.
