🐟 🐧🐧🐧

Weighing the penguins can be a challenge for keepers at the Milwaukee County Zoo.

This video from November released by the zoo on January 5 shows a keeper using a tiny fish called a capelin as a treat for positive reinforcement.

The16 Gentoo and Rockhopper penguins are weighed once a month and keepers keep track of all the penguins by the band on their flippers.
