Meet Some of the Volunteers Behind the Zoo
Behind each animal encounter, educational moment, and unforgettable event at the Smithsonian’s National Zoo and Conservation Biology Institute, there’s a dedicated team of volunteers making it all happen.
Wild Stats: Volunteering by the Numbers
In 2024, an impressive 354 volunteers dedicated a total of 31,574 hours to the volunteer program, with many supporting multiple areas. Here’s where their impact landed:
- 200 assisted staff in the Zoo Aide program
- 120 enhanced the visitor experience as interpreters and event supporters
- 115 assisted with community science and animal monitoring efforts
- 270 short-term volunteers provided invaluable support to special events like Boo at the Zoo and Night of the Living Zoo.
For National Volunteer Month, we’re shining a spotlight on the people who put their time, heart, and energy towards helping the Zoo thrive. We asked several members of the volunteer community to share some of their favorite stories and most meaningful experiences:
John and Jann Hypes
Jann and John, a married couple, are interpreters at the Zoo and ecology aides at the Smithsonian’s Conservation Biology Institute in Front Royal, Virginia. John also serves as a field work volunteer for the Zoo’s camera trap program in Shenandoah National Park.

A Spark of Purpose
As retired science teachers—John from middle school, and I from high school—we sought to continue our passion for education and conservation in our retirement.
We embraced our roles as volunteers, shedding our "teacher hats" and adapting to the ever-changing landscape of the zoo. Our initial days were filled with both excitement and a touch of nervousness. We quickly learned that it's okay not to know every answer, and that the most valuable interactions often come from genuine curiosity.

Cherished Moments
For me, Jann, among my most treasured memories is the Bird House opening, where I was unexpectedly reunited with a former student. Her tearful embrace and heartfelt recollection of our class's Zoo field trip reminded me of the profound impact we can have. John, meanwhile, found a unique connection to history, learning about the Front Royal campus’s role during World War I.
Shared Motivation
What continues to drive us is the opportunity to give back to institutions that empower future generations with knowledge. And, most importantly, it gives us the chance to share the vital message of conservation with people of all ages. We believe that every interaction, every shared fact, contributes to a more informed and compassionate world.

Decades of Experience
When I moved to the D.C. area in 1989, I met a woman at my place of employment who was a volunteer panda watcher at the Zoo. I was immediately interested, and soon was accepted into the volunteer program. I began my first assignment as a panda watcher with the Zoo's very first pandas, Hsing-Hsing and Ling-Ling.
After the panda watch ended several years later, I was curious and open to trying something new. I moved on to other assignments, including the Zoo Lab (the interactive areas used to be called "Labs"), Bird Lab, Golden Lion Tamarin Watch, Cheetah Watch, Reptile Lab, Commissary Aid, Special Events, and eventually, more current Panda Watches.
Zoos as Community Treasures
It gives me great pleasure to be around animals, and when possible, to contribute to their welfare. I view volunteering not only as a way of satisfying my personal needs, but also as a form of community service.
To me, a good zoo is one of the greatest assets a community can have. It never ceases to amaze me how much zoos offer to their communities, how they evolve with the times to stay relevant, how they support the conservation of species, and how they meet the public’s need to stay in touch with the natural world. I strive to be a part of that system, even if it's only in a small way.

An evolving journey
My story began years ago, when I was taking a course in Physical Anthropology at the community college for fun. The class went on a field trip to the Zoo to study the gibbons brachiating. I liked the idea of being at a fun place where I could actively learn. I was taking my son to visit the Zoo when he was little, and then found myself going on my own. Finally, one day I noticed a sign about volunteering at the Zoo, so I decided to apply. I started in 2003 and have been volunteering ever since.
I’ve gained a wealth of information about the various animal species I’ve worked with. I’m surprised how I’ve become so knowledgeable about the animals that I can now relay that information to other people—you kind of absorb it.
Monkey mischief
I have a lot of fun memories, especially from working at the Small Mammal House. I was working in an exhibit with Geoffroy’s marmosets one day, and one of the keepers was getting ready to come in the exhibit. I had my hair pulled back with combs to keep it from falling in my face. Then, I noticed one of the combs being gently pulled out of my hair. I assumed it was the keeper trying to catch the comb from falling out. I turned and saw one of the marmosets with the comb in her hand! She examined it, licked it, looked up at me, and then threw it on the ground!
Ever-changing days
[I’m motivated by] being around the animals—it’s fun and rewarding. You never have the same experience twice. Also, the staff is always appreciative of our help, and they treat us as part of the team. Plus, I always have fun stories to share with family and friends—it’s been better than any paid job I’ve had!

Connecting With Visitors
When talking to visitors, you have to be prepared to discuss anything, including potentially controversial topics. I've learned to be flexible in my approach to visitors and try to use everything that happens as a learning or teaching moment.
The Joy of Mentoring
I have two kinds of "favorite" zoo memories. First, I love when I'm talking to visitors and they become engaged in conversation with each other, usually on a topic related to conservation or nature. It makes me feel like I'm helping other people make connections. Plus, I learn so much from visitors!
Second, I love supporting first-time volunteers during special events. I'm always happy when they finish a shift and tell me they can't wait to volunteer again, or better yet, ask how they can become a "regular" volunteer. Everyone at the zoo has always gone out of their way to make me feel valued, and I want to pass that feeling along to other volunteers.
The ‘Go-To Person’ for All Things Zoo
I've remained a volunteer at the zoo for a few reasons — it's a great chance to talk to people about nature and conservation, even when there's disagreement. I have always loved the informal educational opportunities offered, and it's fun to be the go-to person among friends, family and co-workers for all things Zoo. I also take advantage of the perks of a Zoo badge when visiting other zoos, aquariums and museums.
