The passion for penguins of the British Professor of Marine Biology, Rory Wilson, led him to create the 'Daily Diary', a feather-light, miniaturized device designed to better explore the habitat of endangered animal species. With a single system the professor is able to study the behavior, energy expenditure and movements whether the animal is on land, in water or in the air. What's more, the results show ecologists why a particular habitat is poor, average or optimal, and how big a nature reserve needs for the population of a specific species of animal to survive. It is a way of resolving important questions, for example whether the decline of the African penguin is duet o climate change, predators or overfishing. The Daily Diary can be easily attached to an animal's body for anywhere from an hour to a year and is very easy to remove without disturbing its behavior or movements.
