Animal enclosures need to be hygienically cleaned every day; this is the major part of a keeper’s daily workload and can be very physically demanding depending on which species is involved. Sweeping, hosing, scrubbing, shovelling and window cleaning are repetitive but essential daily tasks. Captive animals confined to enclosures cannot escape their own detritus; the build up of which encourages parasites and pathogens which can then lead to ill health. A keeper must be prepared to work outside in all weather conditions or indoors sometimes in tropically heated environments.
Other duties include the maintenance of animal enclosures, food preparation, providing enrichment and training. Keepers may help design, build and repair animal enclosures; a basic grasp of DIY and gardening skills is required for the upkeep of an exhibit. Being part of a team of like-minded colleagues on an animal section can be very rewarding as well as networking with keepers from other collections. Keepers must also liaise with other professionals within the zoo such as vets, managers and educators.
An understanding of nutrition is essential for good diet management, although in some collections diets are analysed and controlled by an employed nutritionist or manager. Keepers need to keep and prepare feeds, e.g. pellets, fresh produce, meat or hay, in a pest free, clean environment. They will likely determine when the feed is given and how. Often food can be used for enrichment purposes; that is hiding or distributing the feed that will encourage the animal to feed in a way, or at a time, that is more natural for that species. Other enrichment methods are also used to keep animals active and help their psychological wellbeing. It is up to the keepers to use their initiative to make and provide suitable enrichment.
These days, in most institutions, exotic animal care is largely hands off. Even though these are not wild animals they prefer to be with their own kind and over petting or humanising can lead to abnormal behaviours and decrease reproductive success. Instead target training and positive reinforcement is used to condition animal behaviour to make husbandry or veterinary tasks, easier to perform.
Occasionally, keepers must accept that animals in their care are moved to other collections or are euthanized if their quality of life deteriorates, this can be quite an emotional time if a strong bond exists between an animal and a keeper.
Keepers must also be excellent observers, learning habits and behaviours of both individual animals and groups. The keeper knows the animals in their care better than anyone else and must be able to spot subtle signs of injuries or illness and then react accordingly. These responsibilities should not be underestimated since they are essential in maintaining a healthy and reproductively successful animal collection. It is important to maintain accurate and detailed records in a daily diary or computerised system about the events in the animal’s life, identification, births, deaths, sickness, mating behaviour etc. What may seem like minor details at the time may be valuable points of reference at a later date.
Keepers have an important role in education of visitors and of public relations for their institutions. This may involve giving prepared talks to school groups, one to one tour experiences, such as Keeper for a Day, or just chatting to the public as you meet them on your daily rounds. Surveys of visitor experience reveal that interactions with keepers are highly valued by customers and help to increase the public's awareness of the importance of wildlife conservation and global environmental issues that affect the habitat of many threatened species. It is a keeper’s responsibility to educate visitors and they should be knowledgeable about the animals in their zoo, their natural habitat and relevant conservation initiatives. They must be open to interacting with the public at all times, present a smart appearance and be friendly and professional when answering questions.
