To fly or not to fly: high flight costs in a large sea duck do not imply an expensive lifestyle
A perennial question in ornithology is whether flight has evolved mostly to facilitate access to food or as an anti-predator strategy. However, flight is an expensive mode of locomotion and species using flight regularly are associated with an expensive lifestyle. Using heart rate (HR) data loggers...

A perennial question in ornithology is whether flight has evolved mostly to facilitate access to food or as an anti-predator strategy. However, flight is an expensive mode of locomotion and species using flight regularly are associated with an expensive lifestyle.

We used the long-term recording (seven months) of HR as an index of energy expenditure and the HR flight signature to compile all flight events.
