Automatic detection of migrating soaring bird flocks using weather radars by deep learning
Methods in Ecology and Evolution, 2023 The use of weather radars to detect and distinguish between different biological patterns greatly improves our understanding of aeroecology and its consequences for our lives.

A framework for post‐processing bird tracks from automated tracking radar systems
Methods in Ecology and EvolutionRadar is an effective tool for continuous monitoring and quantification of aerial bird movement and used to study migration and local flight behaviour. However, systems with automated tracking algorithms do not provide the level of processing sufficient ...

Dual‐polarization radar products for biological applications
Ecosphere, 2016 The upgrade of the national network of next‐generation weather surveillance radars (NEXRAD) in the United States to dual polarizations has been completed, providing three additional routine data products: total differential phase (ψDP), differential ...

Radar aeroecology – a missing piece of the puzzle for studying the migration ecology of animals [PDF]
Ecography, 2019 In a recent Ecography article, Bauer et al. (2019) identified the most pressing questions for advancing our understanding of how anthropogenic changes in the environment affect aerial migrants at the macroscale and how these changes consequently influence humans.

Riders on the Wind: The Aeroecology of Insect Migrants
, 2017 Migratory flight close to the Earth’s surface (within the so-called flight boundary layer) occurs in some insects, but the vast majority of migrants ascend above this layer and harness the power of the wind for transport. The resulting displacements range from dispersive movements over a few tens of metres to seasonal migrations covering thousands of ...

Animal Migration Patterns Extraction Based on Atrous-Gated CNN Deep Learning Model
Remote Sensing, 2021 Weather radar data can capture large-scale bird migration information, helping solve a series of migratory ecological problems. However, extracting and identifying bird information from weather radar data remains one of the challenges of radar ...

Aeroecological Observation Methods
, 2017 Observation of animals flying in the atmosphere is the core empirical process of aeroecology. For species that are small, or that fly by night or at high altitudes, this presents a considerable challenge. Even for the more visible species and for flights near the ground, recording the animals’ movements requires specialised techniques.

Aeroecology meets aviation safety: early warning systems in Europe and the Middle East prevent collisions between birds and aircraft [PDF]
Ecography, 2019 The aerosphere is utilized by billions of birds, moving for different reasons and from short to great distances spanning tens of thousands of kilometres. The aerosphere, however, is also utilized by aviation which leads to increasing conflicts in and around airfields as well as en‐route.

Associations of Synoptic Weather Conditions With Nocturnal Bird Migration Over the North Sea [PDF]
Frontiers in Ecology and Evolution, 2020 The southern North Sea is part of an important flyway for nocturnal bird migration, but is also risky as it stretches over a large surface of water. Selecting nights with suitable weather conditions for migration can be critical for a bird’s survival ...

Remote Sensing in Ecology and ConservationThe Alps are a natural barrier for avian broad‐front migration in Central Europe. While most birds that approach the Alps are deflected and circumvent the mountains, some choose to make the crossing.
