Batumi Raptor Count@batumiraptorcount.org · 9mo ago

A typical Batumi migration scene, illustrating the idea of an ‘aerial niche’. For Steppe Buzzards in our bottleneck, that niche is often somewhere between the clouds: great to watch, tricky to count. Fascinating paper by @cnilsson.science et al: doi.org/10.1016/j.tr... 📸 @barthoekstra.bsky.social

Online now: Animal niches in the airspace

Animal niches in the airspace

For flying animals, including many birds, bats, and insects, the air is a crucial arena for a range of behaviors. Technological advances, such as year-round tracking of flight altitudes and expanded use of radar, increasingly show how flying animals use the aerial habitat. This enables us to answer questions about the environmental patterns and ecological processes that shape aerial niches, including energetics, biotic interactions, and risk due to growing anthropogenic conflicts. In this review, we identify environmental conditions and biological interactions influencing where animals occur in the airspace throughout their life cycles. We outline an ecological framework to advance understanding of how different properties of the airspace shape fundamental aerial habitat niches and how biotic interactions influence the realized niches.

Are animals randomly distributed in the air, or is there a structure to where and when we find them? In our new paper we outline factors that shape habitat use in the air, from abiotic structure to biotic interactions. A lot of fun discussions behind this one! 🦅🦋🦇🌬 www.cell.com/trends/ecolo...

After a lot of time spent in the darkness of the wind tunnel, the results finally see the light. I'm very excited to share what will become the first chapter of my thesis. Energy conversion efficiency peaks at intermediate flight speed in a migratory songbird www.cell.com/current-biol...

Energy conversion efficiency peaks at intermediate flight speed in a migratory songbird

Using in vivo measurements of thrush nightingales flying in a wind tunnel, Macias-Torres et al. show that energy conversion efficiency varies with airspeed following a concave function, with a maximum...

Weather radars continuously register the movements of billions of animals in the air! We have now published datasets covering large parts of Europe, providing an overview of the aerial habitat in a way no other method can. Data is available on Alofdata.eu , see our blogpost: go.nature.com/3F0wQ0L

Weather radars detect more than weather, they also continuously register the movements of billions of animals (birds, bats, insects) in the air. Those data are now publicly available for large parts o...
