How should prey animals respond to uncertain threats? [PDF]
Frontiers in Computational Neuroscience, 2011 A prey animal surveying its environment must decide whether there is a dangerous predator present or not. If there is, it may flee. Flight has an associated cost, so the animal should not flee if there is no danger.

Animal-Inspired Agile Flight Using Optical Flow Sensing [PDF]
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012 There is evidence that flying animals such as pigeons, goshawks, and bats use optical flow sensing to enable high-speed flight through forest clutter.

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 ...

Wake development behind paired wings with tip and root trailing vortices: consequences for animal flight force estimates. [PDF]
PLoS ONE, 2014 Recent experiments on flapping flight in animals have shown that a variety of unrelated species shed a wake behind left and right wings consisting of both tip and root vortices.

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 ...
