To be able to see what and how much exactly a penguin eats after a single fishing dive, the quickest way to do so is to force-pump water down its throat. The penguin is then held firmly, preferably under the armpit like a bagpipe and aimed at a nearby bucket. Pressure is then applied to the bloated penguin's stomach.
An alternative method is to force pump salt water instead, leaving the penguin to vomit everything out on its own. This is however can be more stressful to the bird than the former method, so isn't too common.
