(Most) Humboldt penguins are masters of weigh-in daypublished at 11:31 British Summer Time 19 August

The scale is no stranger to the Zoo’s Humboldt penguins, who have been practising weigh-ins all year round.
Their zookeeper, Jess Ray, tells us that the penguins have been getting accustomed to the scales since they were chicks.
That by no means makes it an easy job for Jess and her fellow zookeepers. They’ll be weighing all 79 of the Zoo’s penguins across a few days. The toughest of whom, is called Petal.
“She’s quite a shy penguin. She’s gotten more and more comfortable over time but she’s usually the tricky one,” says Jess.
Humboldt penguins are typically found on the islands and rocky coasts of Peru and Chile.
Contrary to popular belief, only four of 18 penguin species live in cold climates full-time.
