TL;DR: In this paper , the authors used body-mounted accelerometers for estimating power use in flying birds, as the signal varies with the two major kinematic determinants of aerodynamic power: wingbeat frequency and amplitude, and found that birds were more likely to modulate amplitude for more energy-demanding flight modes, including climbing and take-off.

McKee,Lorien Pichegru,Pascal Provost,Niels Christian Rattenborg,P. Ryan,Carlos David Santos,Stefan Schoombie,Vikash Tatayah,Henri Weimerskirch,Martin Wikelski,Emily L. C. Shepard +19 more
TL;DR: For example, this article analyzed > 300,000 hours of tracking data from 18 seabird species, including flapping and soaring fliers, to assess how flight morphology affects wind selectivity, both at fine scales (hourly movement steps) and across the breeding season.
Thermal soaring in tropicbirds suggests that diverse seabirds may use this strategy to reduce flight costs
Baptiste Garde,Adam J. Fell,K. S. Krishnan,CG Jones,Richard Gunner,Vikash Tatayah,Nc Cole,E. Lempidakis,Elc Shepard +8 more
TL;DR: Thermal soaring, previously thought to be limited to birds with low wing loading, is observed in red-tailed tropicbirds, suggesting diverse seabirds may use this strategy to reduce flight costs, particularly with tailwinds and during non-breeding seasons.

Ecological inference using data from accelerometers needs careful protocols
Baptiste Garde,Rory P. Wilson,Adam J. Fell,Adam J. Fell,Nik C. Cole,Vikash Tatayah,Mark D. Holton,Kayleigh A. R. Rose,Richard S. Metcalfe,Hermina Robotka,Martin Wikelski,Martin Wikelski,Fred Tremblay,Shannon Whelan,Kyle H. Elliott,Emily L. C. Shepard +15 more
TL;DR: In this article, the authors examined the absolute accuracy of tri-axial accelerometers and determine how inaccuracies impact measurements of dynamic body acceleration (DBA), as the main acceleration-based proxy for energy expenditure.

TL;DR: Simulations were performed to examine the extent of dead-reckoning error, relative to VPs, as a function of Verified Position correction (VP correction) rate and the effect of this on estimates of distance moved and it is demonstrated how sources of measurement error can arise within VP-corrected dead- Reckoning tracks.
