We were honored to welcome a very special guest to DZCA last week: Dr. Roberto Elias, wildlife veterinarian and one of our longest-standing conservation partners in Peru! 🐸
Roberto has been working alongside Denver Zoo Conservation Alliance since 2008, when our collaborative breeding program for the Titicaca water frog first began. In the years since, that partnership has grown to include the Lake Junín frog, Andean condors, and flamingos.
Using drone technology, Roberto and his team have recently discovered a new Andean condor nest (only the fourth ever reported in Peru!) and identified a new flamingo breeding site at Lake Junín. Data that is now directly informing government conservation policy.
As Roberto puts it, conservation comes down to three things: science, community, and action.
“You cannot conserve a species if you don’t know them. If you don’t involve the community, you cannot do this sustainably. And all the information that we get, we turn into action.”
When you visit DZCA, you’re not just seeing the animals here, you’re supporting the work happening on the ground in Peru.

FLOCK YEAH! Flock Party 2026 was our biggest and best yet, all because of you! 🦩✨💖
We toasted 130 years of Denver Zoo Conservation Alliance, spent an afternoon enjoying MORE animal experiences, food, drinks and live music, and most importantly, celebrated conservation in style.
Thank you for joining us, celebrating with us and supporting world-class animal care and wildlife conservation. We truly couldn`t do this without you.
Until next year! 💕
Hesty, our Critically Endangered Sumatran orangutan mother, is the queen of posing for the camera and knowing her angles. She’ll teach baby Rambutan everything he needs to know like how to eat and serve ✨💅🦧

Araali, our six-year-old African lion, will soon embark on a new adventure! 🦁
This fall, Araali is moving to another zoo accredited by the Association of Zoos and Aquariums as part of the African Lion Species Survival Plan (SSP). Following her arrival, a male lion from another institution will also join her, and the pair will be housed together as a new social group.
Araali gave birth to four cubs in August 2025, and while her departure may feel premature for cubs who`ve just turned a year old, this change came as a result of animal-led decision-making and in response to behavioral changes between the cubs and their mother. Over the last few months, our Animal Care team noticed changes in the relationship between Araali and her cubs. While they closely monitored these changes and explored various ways to maintain this family group, it became clear through Araali’s behavior towards the cubs that she was more comfortable with separation. Through careful consideration and with support from the SSP, we were able to find a new home for Araali where she can continue to receive excellent care and have the opportunity to form a new social group.
As for our not-so-little cubs, they are fully weaned, eating independently and physically ready for more independence. They had the opportunity to learn important behaviors from their mom and will continue to learn from and observe other adult lions as they continue to grow at DZCA. While this separation happened a bit sooner than expected, it reflects our commitment to making the best animal care decisions possible based on what the animals are telling us. The cubs will remain at DZCA for now and we’re happy to provide them with a good home as they continue to grow and mature. As they get older, they may receive recommendations from the SSP for future moves.
Araali was born at DZCA in 2020 and has been a special part of a multi-generational pride ever since. It’s been our pleasure to care for her and watch her grow into the incredible lion she is today. We’ll certainly miss this feisty feline at Predator Ridge, but we’re so excited for her next adventure and the new companionship that awaits her.
