Four Magellanic penguins officially left the nest and took their first swimming lesson before appearing in front of the audience.

The penguin chicks recently gave up fluffy feathers for juvenile waterproof feathers and had their first introduction into the water for their first bath at Shedd Aquarium in Chicago. The great footage was shared by the Aquarium Team on 5th August.

According to Shedd Aquarium in addition to their first swim, the penguin chicks have been reaching additional developmental milestones, including eating fish, socializing, and exploring new spaces around the aquarium, and more.

The chicks are also starting to build relationships with the animal care team.

Regular check-ups with the aquarium’s animal care team show that birds are hitting all their growth targets and a test of biological samples taken from the chicks’ eggshells will help determine their sexes since penguins’ reproductive organs are internal.

Once the sex of the birds is determined, the aquarium will share any potential naming plans for the birds and the expected timing for when guests can see the newest arrivals.

Although these four chicks have not yet joined the mature colony at Shedd’s Polar Play Zone, the public can plan a visit to the aquarium to see the rest of the penguin colony to come face to face with the birds.
