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.

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 ...

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.

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.

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.

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

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.

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.

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.
