... ubiquitous in natural habitats. Hummingbirds are ideal organisms for studying the influence of freestream turbulence on flight, as they forage in a variety of aerial conditions and are powerful flyers. We filmed ruby-throated hummingbirds ( Archilochus colubris ) maintaining position at a feeder in laminar...

...Peng Chai; Johnny S. C. Chen; Robert Dudley ABSTRACT Maximal load-lifting capacities of six ruby-throated hummingbirds ( Archilochus colubris ) were determined under conditions of burst performance. Mechanical power output under maximal loading was then compared with maximal hovering performance...

... hummingbirds ( Archilochus colubris ) was manipulated non-invasively using hyperoxic but hypodense gas mixtures of sea-level air combined with heliox containing 35 % O 2 . This manipulation sheds light on the interplay among metabolic power input, mechanical power output and aerodynamic force production...
