Stuff To Blow Your Mind The Extreme Maneuverability of Hummingbirds, with Roslyn Dakin
Jun 26, 2025
Roslyn Dakin, an Associate Professor at Carleton University and principal investigator at the Dynamic Behavior Lab, shares her insights on the incredible flight dynamics of hummingbirds. She discusses their impressive maneuverability and the remarkable adaptations that allow them to compete fiercely for territory and food. Dakin reveals how their aerial displays play a crucial role in courtship, and explains the relationship between a hummingbird's power reserves and their flight capabilities. The conversation brings to light their cognitive abilities and the impact of human interactions on their evolution.

Episode notes
Evolutionary Roots of Hummingbirds
- Hummingbirds evolved from acrobatic insectivorous ancestors similar to swifts about 30 million years ago.
- Their extreme maneuverability and flight power stem from this evolutionary background and adaptation for nectar feeding.
Power Limits Maneuverability
- Hummingbird maximum turning performance in free flight matches the load lifting maximum power output measured in controlled assays.
- This shows their acrobatic maneuvers depend on muscular power reserve capabilities.
Hummingbird Jousting Battles
- Hummingbirds use their sharp bills as weapons during fights over territories, often orienting bills toward each other like jousts.
- These confrontations rarely lead to contact in lab settings due to the danger posed by their size and agility.
