The use of multi-sensor drone data for the development and validation of methods to track and characterize marine animals [PDF]

open access: yesScientific Reports
Low 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 ...

Flying through gaps: how does a bird deal with the problem and what costs are there?

open access: yesRoyal 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.

Coupling Atmospheric and Biological Remote Sensing to Investigate Boundary-Layer Evolution and Animal Flight Behavior as Affected by the 2017 North American Solar Eclipse

open access: yesRemote 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

Oceanic and Atmospheric Correlations to Cetacean Mass Stranding Events in Cape Cod, Massachusetts, USA

open access: yesGeophysical 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]

open access: yesCurrent 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.

Soaring migrants flexibly respond to sea-breeze in a migratory bottleneck: using first derivatives to identify behavioural adjustments over time

open access: yesMovement Ecology, 2023
Background Millions of birds travel every year between Europe and Africa detouring ecological barriers and funnelling through migratory corridors where they face variable weather conditions.

Diurnal Flight Activity of House Flies (Musca domestica) is Influenced by Sex, Time of Day, and Environmental Conditions

open access: yesInsects, 2020
House flies (Musca domestica L.) are common synanthropic pests associated with confined animal operations, including dairy farms. House flies can cause substantial nuisance and may transmit human and animal pathogens.

Controllable factors affecting accuracy and precision of human identification of animals from drone imagery

open access: yesEcosphere, 2023
Surveying animal populations using drones (unoccupied aircraft systems [UAS]) provides numerous advantages; however, few best practices exist to survey animal communities with drones.

Wing Design in Flies: Properties and Aerodynamic Function

open access: yesInsects, 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.

A dynamics and stability framework for avian jumping take-off [PDF]

open access: yesRoyal 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.
