A perception-action strategy for hummingbirds [PDF]
, 2010 Many human and animal tasks are thought to be controlled with the tau informational variable. It is widely accepted that controlling the rate of change of tau during decelerative tasks, such as when braking or landing, is one common perceptual control ...

Adipose energy stores, physical work, and the metabolic syndrome: lessons from hummingbirds
Nutrition Journal, 2005 Hummingbirds and other nectar-feeding, migratory birds possess unusual adaptive traits that offer important lessons concerning obesity, diabetes and the metabolic syndrome. Hummingbirds consume a high sugar diet and have fasting glucose levels that would
