Interview Process

All qualified applicants will be scheduled for an interview. Applicants will receive an email for an interview to take place on a convenient date and time. Interviews may be video-based or in-person and will last approximately 30 minutes. Selection for the program is based on the candidate’s responses in the interview.

Program Fee

There is a fee to cover the purchase of the Volunteer uniform shirt and training costs. The $50 fee for this program is due on the first day of training and is non-refundable.


In order to develop the skills required and feel confident in one’s abilities, training and practice is required. All selected candidates will participate in on-line training as well as in-person sessions. Some training will be “learn-as-you-go” such as when training with the Zookeepers for Animal Care positions. Naturalist training requires the most training and practice to be proficient in speaking with the public about the animals. The extent of training will be dependent on the position for which the volunteer is selected.

Volunteer Opportunities

Zoo Naturalist

Help educate zoo guests about conservation, animal behavior, and nature. Naturalist attend training on zoo history, interpretation skills , and receive detailed information on all animal areas of the zoo. Whether in front of an animal habitat or leading a tour, these positions are essential to connecting people to animals and nature.

Animal Care

Assist zookeepers in maintaining animal habitats, preparing animal diets, and providing behavioral enrichment. Be prepared to get dirty and work in all weather conditions. Since the well being of our animals is dependent on our animal care staff, volunteers in this area must be extremely dependable.

Animal Behavior Observer

An important function in maintaining good animal welfare is the observation of animals and their behavior to identify personality traits, evaluate animal health, see how enrichment encourages natural behavior, and to provide even better care for the animals.


Assist our conservation educators at zoo camps, classes, and field trips by helping to prepare activities and supervise children. Help set up and operate activity stations at education events as well as oversee guest participation.


One of the most important ways to stimulate natural behaviors in animals is by providing enrichment.  Help create behavioral and environmental enrichment devices at the Niabi Enrichment Supply & Task Center, a.k.a. the NEST. Duties may include painting, drawing, cutting, pasting, braiding, and assembling items to be given to our animals.


Like gardening? Get down in the dirt to help us maintain our flower beds, pollinator gardens and planting areas. Duties include routine plant care, such as watering, pruning, weeding, planting, and transplanting. Horticulture volunteers should be prepared to work in all weather conditions.
