The Shedd Aquarium, which recently reopened in Chicago after months of closure due to the coronavirus pandemic, has been delighting animal lovers from home with videos of their birds waddling around the wildlife habitat.

Now, two of the adorable critters have broken out from their aquatic campus.

Penguin pair Izzy and Darwin recently spent some time cruising around Chicago’s Field Museum of Natural History, reconvening with some long lost prehistoric relatives: SUE the T. rex and Máximo the Titanosaur. The bonded birds are Magellanic penguins, a South American species, related to dinosaurs like SUE, going back 66 million years according to the bio-experts.

Previously, penguins Edward and Annie have visited tanks holding Southeast Asian species at their local Shedd Aquarium, while their pal Wellington looked at tetra fish and ones from the Amazon. Other activities the animals have indulged in while museum-goers wait out the pandemic at home: otters Kiana and Yaku cooled down on a pile of ice, and Annik, a dolphin, celebrated his first birthday.

According to Shedd, the Field Museum will be reopening in the coming weeks to accommodate human guests as well.

Izzy and Darwin, from the Shedd Aquarium, stretch their wings and visit their neighbors at the Field Museum.
