MistNet: Measuring historical bird migration in the US using archived weather radar data and convolutional neural networks

Methods in Ecology and Evolution, 2019
Large networks of weather radars are comprehensive instruments for studying bird migration. For example, the US WSR‐88D network covers the entire continental US and has archived data since the 1990s.

Bird Migration

open access: yes, 2010
The phenomenon of bird migration has fascinated people from time immemorial. The arrivals and departures of different species marked the seasons, heralding spring and autumn, and providing a reliable calendar long before anything better became available.

Automated acoustic monitoring captures timing and intensity of bird migration

Journal of Applied Ecology, 2022
1 1: Monitoring small, mobile organisms is crucial for science and conservation, but is technically challenging. 2 Migratory birds are prime examples, often undertaking nocturnal movements of thousands of kilometres 3 over inaccessible and inhospitable ...

Explaining Bird Migration

Science, 2010
Predation pressure falls with increasing latitude, helping to explain why many birds migrate as far north as the high Arctic.

Holding steady: Little change in intensity or timing of bird migration over the Gulf of Mexico

Global Change Biology, 2019
Quantifying the timing and intensity of migratory movements is imperative for understanding impacts of changing landscapes and climates on migratory bird populations.

Detours in Bird Migration

Journal of Theoretical Biology, 2001
Bird migration routes often follow detours where passages across ecological barriers are reduced in extent. This occurs in spite of the fact that long barrier crossings are within the birds' potential flight range capacity. Long-distance flights are associated with extra energy costs for transport of the heavy fuel loads required.
