The Denver Zoo Conservation Alliance is a large 80-acre (32 ha) zoo in Denver, Colorado. It's a special place dedicated to protecting animals and their homes in the wild. The zoo first opened way back in 1896 and is located inside Denver's beautiful City Park. It's the most popular paid attraction in the whole city!

The zoo got its start with a special gift: an orphaned American black bear. From the beginning, the Denver Zoo wanted to create homes for animals that felt like their natural habitats. Instead of small cages with bars, they built large, open spaces. A great example is Bear Mountain, which was one of the first exhibits in the United States to look like a real mountain.

The zoo is a member of important groups like the Association of Zoos and Aquariums (AZA) and the World Association of Zoos and Aquariums (WAZA). This means it meets very high standards for animal care. The zoo also cares a lot about the environment and has won awards for being one of the "greenest" zoos in the country.

History of the Zoo

How It All Began

The Denver Zoo started in 1896 with an American black bear cub named Billy Bryan. The cub was given as a gift to the mayor of Denver, who then gave him to the keeper of City Park. This single bear was the first animal in what would become the Denver Zoo. Soon, other local animals joined, like ducks, prairie dogs, and pronghorn antelope.

For many years, the zoo focused on animals native to Colorado, like large herds of bison and elk. In 1905, they added red squirrels, but the squirrels had so many babies that they started causing problems for the bird population! The zoo had to carefully move the extra squirrels to the nearby mountains.

Building a Modern Zoo

In 1906, Denver's Mayor Robert W. Speer had a big idea. He wanted to get rid of the "prison bars" and create natural-looking homes for the animals. He hired designers to make this happen.

Their most famous creation was Bear Mountain, which opened in 1918. This huge structure was made to look like real mountains near Morrison, Colorado. Instead of bars, hidden moats kept the animals safely in their habitat. It was first home to polar bears and grizzly bears. The exhibit was so amazing that other zoos, like the one in St. Louis, hired its designer to build similar habitats.

One famous resident of Bear Mountain was a polar bear named Velox. She lived there for 20 years and even became the mascot for a U.S. Army group. You can still see a memorial for her at the zoo today.

After Bear Mountain, the zoo continued to grow. Monkey Island was built in 1937. In the 1950s, the zoo got its first elephant, named Cookie. Over the next few decades, many new buildings were added, including the Feline House for big cats, a Giraffe House, and Bird World.

Recent Changes and Events

Denver Zoo's Tropical Discovery

In 1993, the zoo opened Tropical Discovery, an amazing indoor rainforest. This exhibit is full of fish, reptiles, and other tropical animals. It's like taking a trip to the jungle right in the middle of Denver!

In 1994, twin polar bear cubs named Klondike and Snow were born. Their mother couldn't care for them, so the zoo staff raised them by hand. They became huge stars at the zoo, and a bronze statue was created to remember their story.

Sadly, in 2007, a zookeeper was seriously injured in an accident involving a jaguar and later passed away. The zoo's emergency team responded, but it was a very sad day. The zoo learned from this event to make its safety rules even stronger.

In 2012, the huge Toyota Elephant Passage opened. It's one of the largest habitats for male elephants in the world. In 2024, the zoo announced a major expansion. It received 570 acres of land in a nearby county. This new area, called the Lembke Family Preserve, will give the zoo more space to breed endangered animals and help return them to the wild.
