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 ...

Flocking together : collective animal minds in contemporary fiction [PDF]
, 2020 The remarkable coordination displayed by animal groups such as an ant colony or a flock of birds in flight is not just a behavioral feat; it reflects a full-fledged form of collective cognition.

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.

Remote Sensing, 2020 The daytime atmospheric boundary layer is characterized by vertical convective motions that are driven by solar radiation. Lift provided by thermal updrafts is sufficiently ubiquitous that some diurnal birds and arthropods have evolved specialized flight

Geophysical Research Letters, 2021 Groups of pelagic dolphins and whales (order Cetacea) regularly strand on beaches throughout the world. These strandings are referred to as mass stranding events (MSEs). MSEs have been observed for centuries, however the underlying causes remain unclear.
