Finally, a big shout out to all the #eBirders recording birds in mountains without whom this research would not be possible!

This work provides a quantitative framework and a basis for understanding and predicting how mountain birds will cope with global change.

These results suggest that elevational gradients in avian distributions might be a condensed version of corresponding latitudinal gradients, and that altitudinal migration serves the same ecological purpose as long-distance migration.

Instead, bird movements match what would be expected if they were trying to acquire and use energy in the most efficient way based on today’s environments, with computer models simulating what birds should do to optimise energy budgets corresponding with what they do in real life.

We found that altitudinal migration is a notable phenomenon globally, and that many birds do not strictly follow the temperatures they are supposedly adapted to. Many populations even migrate upslope during winter, therefore tracking thermal conditions worse than if they actually stayed put.

To test this, we analysed vast amount of #eBird data. We looked at seasonal changes in the elevational distributions of birds - how high in the mountain birds go at different times of year - for nearly 11,000 avian populations across 34 mountain regions worldwide.

One theory is that it's mostly because of long-term evolution, and the climate niches species have adapted to over long time.

Another - the ‘energy efficiency’ hypothesis -suggests it is about how species today manage their energy budgets and compete for resources varying in space and time.

The fact that biodiversity varies along mountain gradients has long been established but it is not clearly understood why this is the case

Why is there such variation in the birds encountered as you go up or down a mountain? New paper in #ScienceAdvances examines how climate and ecological interactions drive bird distributions in mountains throughout the year:

As someone trained as both a field ecologist and quantitative scientist, this tension runs deep for me. Some of my group are entrenched in the field whereas others work with models for a living.

What if sensor equipped drones could autonomously hop around landscapes to survey biodiversity?

Would data be reliable? Could we adapt survey design in real-time?
