The use of multi-sensor drone data for the development and validation of methods to track and characterize marine animals [PDF]
Scientific ReportsLow cost, unmodified, commercially available drones can provide an effective platform for the study and characterization of marine megafauna. We present methods which utilize video and flight data to allow for both the continuous tracking of animals and ...

Non-canonical function of an Hif-1α splice variant contributes to the sustained flight of locusts
eLife, 2022 The hypoxia inducible factor (Hif) pathway is functionally conserved across metazoans in modulating cellular adaptations to hypoxia. However, the functions of this pathway under aerobic physiological conditions are rarely investigated. Here, we show that

Hovering hummingbird wing aerodynamics during the annual cycle. II. Implications of wing feather moult [PDF]
Royal Society Open Science, 2018 Birds usually moult their feathers in a particular sequence which may incur aerodynamic, physiological and behavioural implications. Among birds, hummingbirds are unique species in their sustained hovering flight.

A dynamics and stability framework for avian jumping take-off [PDF]
Royal Society Open Science, 2018 Jumping take-off in birds is an explosive behaviour with the goal of providing a rapid transition from ground to airborne locomotion. An effective jump is predicated on the need to maintain dynamic stability through the acceleration phase.

Flying through gaps: how does a bird deal with the problem and what costs are there?
Royal Society Open Science, 2021 Animals flying in the wild often show remarkable abilities to negotiate obstacles and narrow openings in complex environments. Impressive as these abilities are, this must result in costs in terms of impaired flight performance.

Hovering hummingbird wing aerodynamics during the annual cycle. I. Complete wing [PDF]
Royal Society Open Science, 2017 The diverse hummingbird family (Trochilidae) has unique adaptations for nectarivory, among which is the ability to sustain hover-feeding. As hummingbirds mainly feed while hovering, it is crucial to maintain this ability throughout the annual cycle ...

Animal Behavior: Fly Flight Moves Forward [PDF]
Current Biology, 2013 A new study has resolved the paradox of how flies maintain reflexive aversion to your approaching swatter, whilst tolerating similar visual signals during normal forward flight.

Wing Design in Flies: Properties and Aerodynamic Function
Insects, 2020 The shape and function of insect wings tremendously vary between insect species. This review is engaged in how wing design determines the aerodynamic mechanisms with which wings produce an air momentum for body weight support and flight control.

Humming hummingbirds, insect flight tones, and a model of animal flight sound [PDF]
Journal of Experimental Biology, 2020 Why do hummingbirds hum and insects whine when their wings flap in flight? Gutin proposed that a spinning propeller produces tonal sound because the location of the center of aerodynamic pressure on each blade oscillates relative to an external receiver.
