There's been a baby boom at Chicago zoos this summer. The city's newest residents are also some of its cutest, from rare newborn rhinos to friendly sea otter pups. Check out some adorable photos of the baby animals, then go see them for yourself at Chicago's zoos and aquariums.

Lincoln Park Zoo

Chicago's oldest zoo is now home to a new crop of baby animals. Their family of western lowland gorillas, a critically endangered species, welcomed two new babies this summer. Bana, a 24-year-old gorilla, gave birth to healthy infant Djeke on June 12. That happens to be exactly one month after the arrival of another male infant, Mondika, born to Rollie on Mother's Day. Exhibit hours may vary with the new arrivals, call ahead or check their website for viewing hours of new baby animals.

Located just outside Chicago, Brookfield Zoo is a great spot to see baby animals this summer. The zoo welcomed a male sea lion pup, three bat-eared fox kits, five mongoose pups, and seven common peafowl chicks this summer. Exhibit hours may vary with the new arrivals, call ahead or check their website for viewing hours of new baby animals.

Shedd Aquarium

A leader in animal care, the Shedd has a few surprise additions this season. In expected arrivals, their beluga whale gave birth to a healthy male calf and two new Magellanic penguin chicks hatched earlier this summer. When two sea otter pups were orphaned in California, the Shedd quickly stepped up to care for the baby critters. Exhibit hours may vary with the new arrivals, call ahead or check their website for viewing hours of new baby animals.
