Are you interested in helping with the dirty side of a keeper’s job? This is the team for you!

Keeper assistant jobs help with routine day-to-day work, such as cleaning, dish-washing and diet preparations. While keeper assistants work near our animals, these positions do not involve direct animal contact, handling or training. Keeper Assistant jobs are not the most glamourous position in the Adult Volunteer program, but your efforts free up time for keepers to provide exceptional care for our animals. While our volunteers work in many areas of the zoo, we cannot guarantee that positions will be open in every area nor will we have enough open positions for every new volunteer. These positions require a negative tuberculosis test and additional training before you are able to volunteer.

Below are the potential areas of volunteering. When the application opens, we will post only the areas that have availability. Volunteers may select a preference, but animal care staff select individuals based on need. 

Areas of Volunteering*:

  • Animal Ambassadors: Clean animal enclosures, create enrichment for animals and assist animal care staff with various tasks.
  • Birds: Clean and sanitize food bowls and other items, cut up fresh fruit and raw meat (chicks, mice and fish) for diets per keeper instructions and clean out cages. May also wipe counters, clean sinks, wash and fold laundry and help prepare diets as needed.
  • Carnivores: Wash dishes, prepare raw meat, fish and produce diets and general housekeeping duties.
  • Hoofstock: Clean yards, exhibits and stalls (which includes raking, shoveling, sweeping, hosing and hauling hay/alfalfa), assist with diet distribution (grains, vegetables, fruit, hay, alfalfa, etc.) and assist animal care staff with various tasks.
  • Pachyderms: Prepare produce diets, clean outside and inside enclosures, move hay and assist animal care staff with various tasks.
  • Predators: Prepare raw meat diets, clean outside enclosures and inside enclosures, clean windows, create enrichment for animals and assist animal care staff with various tasks.
