Secret of the Puking Penguins is on S.T.E.M. Friday.

When does a stomach stop working like a stomach? When does it stop digesting food and start preserving it instead? What can be more important than having a daily dose of nutrition? It turns out that
the King penguin, which is the second largest penguin, has successfully adapted this strategy to increase its chick's chances of survival in a very cold place. French scientists travelled to the Crozet Archipelago, a group of islands south of Madagascar, where a large colony of King penguins lives. Like other birds, King penguin dads regurgitate on their chick's mouth to feed them. But in many occasions, dad had not eaten for the last three weeks, so their stomach should be empty. Hmm... Was it? The way to answer this question was to take a look at the penguin's stomach content, so imagine yourself surrounded by hundreds of noisy penguins with a very sharp beak and trying to take a sample of one of the big bird's stomach. Not easy, but the scientists succeeded and found out how the King penguin's stomach preserves fish and squid fresh for its baby chick. The baby gets the most needed food until mom gets back from a feeding feast at sea and trades baby care duties with dad. Amazing adaptations!
