Open AccessUsing weather radar to monitor the number, timing and directions of flying-foxes emerging from their roosts
Knowledge of species’ population trends is crucial when planning for conservation and management; however, this information can be difficult to obtain for extremely mobile species such as flying-foxes (Pteropus s...

Open AccessThe movement of small insects in the convective boundary layer: linking patterns to processes
In fine warm weather, the daytime convective atmosphere over land areas is full of small migrant insects, among them serious pests (e.g. some species of aphid), but also many beneficial species (e.g. natural e...

The Pulse of the Planet: Measuring and Interpreting Phenology of Avian Migration
Changing phenology of bird migration has become a flagship example of the biological impacts of climate change. Bird migration phenology data come from a limited number of time series in idiosyncratic location...

Open AccessElectromagnetic Model Reliably Predicts Radar Scattering Characteristics of Airborne Organisms
The radar scattering characteristics of aerial animals are typically obtained from controlled laboratory measurements of a freshly harvested specimen. These measurements are tedious to perform, difficult to re...

Open AccessNocturnally migrating songbirds drift when they can and compensate when they must
The shortest possible migratory route for birds is not always the best route to travel. Substantial research effort has established that birds in captivity are capable of orienting toward the direction of an i...

Influence of atmospheric properties on detection of wood-warbler nocturnal flight calls
Avian migration monitoring can take on many forms; however, monitoring active nocturnal migration of land birds is limited to a few techniques. Avian nocturnal flight calls are currently the only method for de...
