The great tinamou is a smallish turkey-like bird known for its colourful, smooth, glossy eggs. In short, the eggs are wicked cool. But exactly how great tinamous produce their positively alien-looking eggs has largely been a mystery, until now.
Researchers at the University of Akron in Ohio got their hands on a clutch of great tinamou eggs from the University of Michigan Museum of Zoology and subjected them to a litany of tests, including chemical analysis and electron microscopy, to find out how they get their glossy coating and vivid colour. The results were published today in Interface[1], a journal of the Royal Society B.
The first thing the team discovered was that the tinamou eggs were iridescent; they change colour slightly, depending on what angle youre looking at them from.
