purpose of the visit was to introduce a 6 year old orphan female
chimpanzee to her new surrogate parents; to introduce two
singly-housed male chimpanzees to one another; to introduce any
other singly-housed primates into group settings; to reorganize
basic husbandry routine and start an enrichment plan for all

desirable. If that cannot be obtained, the use of contraception is

introductions. All other cages needed doors to connect as well as
some new bars to hold animals.
due to different viewpoints and a lack of drugs and working shift
doors, the two single housed male chimpanzees could not be put
together. Mr. Lamine and I will work on this project in the near
introduction of an approximately 6 year old female chimpanzee
(Edgar) to surrogate pair was successful. Edgar was raised by
humans and had no species-typical social skills. Initially she was
apprehensive of the adult female chimpanzee but in less than two
days they bonded. Video: http://www.youtube.com/watch?v=Kty1zuudxEU

prompting her to play and they appear to be a good family.

Sydney grooms Edgar
Another interesting note: I was told that prior to the
introduction of Edgar to the adult pair, Kong and Sydney were
mostly ignoring each other, sitting far from each other all day
long, and almost never interacting. That was also my impression
during my short stay. Once they were separated (in order to do
Edgar’s introduction to Sydney), interestingly, they constantly
protested for being away each other, tried to groom, play and
comfort one another very frequently though the mesh or tried to
open the door so they could reunite. After all three of them
were put together, they were inseparable.
Suggestions: Chimpanzees need to be kept in social groups. If
obtaining additional females is not feasible, bachelor parties
need to be created.
animals from one cage to another was a difficult task due to lack
of permanent veterinary staff as well as funds to call a
veterinarian and/or immobilize so many chimpanzees at the same
veterinarian with permanent status could be secured.
for substrate, browse for foraging and nest building, logs and
larger branches and a tire for furniture was placed into the
chimpanzee cages. Suggestion: Clean
hay needs to be put into cages every week. Hay can be spot cleaned
daily and replaced at the end of the week, cages need to be hosed
and new hay needs to replace the old. Browse needs to be provided
daily for chimpanzees, especially for nest building. These animals
build a nest twice a day, one for day time and one for
night. Eventually, having them build some type of nest structure
up high in the cages would be desirable since these animals sleep 30-50
Feet high in the wild.

15.24m) up in the canopy

To further improve quality, permanent and flexible
furniture needs to be installed in each cage. Animals need both to
develop/exhibit proper motor skills.
In most of the enclosures, animals can only use floor space.
Exhibits should utilize three dimensions by adding large tree
trunks, ropes, fire hoses, hammocks, wooden shelves, etc., to
increase space and to the animals’ opportunities for exercise,
exploration and manipulation. Furniture needs to be built from
wood, ropes or any kind of natural materials as opposed to metal.
with hay or browse nest.
chimpanzees needed diet improvement. Usually they were fed every
second day, more often than not only dry bread and some half
spoiled fruit. They mostly relied on being fed by the visitors.
Diet lacked fresh greens, vegetables, seeds and animal protein
(meat, eggs, milks, and insects). The chimps at Gombe kill and eat as much as one-third of the colobus monkey
population in the park each year. In West Africa they prey on bush
babies. This alone was a major scientific find which challenged previous conceptions
of chimp diet and behavior.
Diet usually contains less carbohydrates and fiber in captivity.
oranges, melons, bananas, mangos, berries, etc.)
(cabbages, lettuces, cucumbers, carrots, yams, sweet potatoes,
willow, bamboo, tipu, sugar cane, carob, elm, pine, acacia,
mesquite, sissoo, salt cedar, palm fronds, etc.)
primate diet (monkey chow)
catmint, lavender, rosemary, etc.)
rice, popcorn, parrot mix, sunflower, nuts, etc.)
(bread, cereals, etc.)
To compensate for animal protein:
wax worms, superworms, grasshoppers, crickets, etc.) and
quail, duck, etc.)
products (milk, powdered milk, yogurt, etc.)
Suggestions: Due to lack of resources it is understandable that
not all desired food products can be obtained, but the chimpanzees
could receive rice, milk, seeds and hard boiled eggs for protein
every day, 3 times per day. These items are quite cheap and
accessible. Diet needs to be chopped into small pieces and widely
scattered so alpha males would not be able to monopolize desired
trying to interact.
Patas monkey immobilized and ready for introduction
There were many monkeys housed alone such as
Guinea baboon (Papio papio),
patas monkeys (Erythrocebus
patas) and vervet monkeys
Due to the zoo not having enough animals to fill the cages and the
Ministry not allowing empty cages, the situation presented some
real problems. However, Mr. Lamine really wanted to make some
positive changes and allowed us to put some animals together. They
are not all in correct social groups yet, however, but at least
are paired up (male-male; male-female, whatever combination we had
Suggestion: Social animals need to be kept with their conspecifics
in correct group setting. There was much debating over the
primates and carnivores current and future welfare. A general
agreement was made that in the future, when the zoo receives
additional animals, they will be paired up.
All cages were filled with substrate, browse and grass.
Since feeders, puzzle feeders or any type of feeding devices were
not available, most primates received grass on the top of their
cage and chopped diet in substrates (hay and browse) at the bottom
of the cages for foraging.

Common Warthog (Phacochoerus africanus)
was an unknown aged, suckling warthog piglet found by itself in
very bad shape. Animal was kept in a dark, empty, hot cage and was
fed dry bread and water and had some skin problems. Milk powder
was purchased and animal was fed immediately. We also found a
larger cage with plenty of shade and fixed it up. The animal now
has soil, browse, bark, logs, hay, a wallow and separate dishes
for water and milk.

Suggestions: the piglet needs to be fed 4xday with milk, seeds,
fresh fruit and vegetables. I left some Hydrocortisone cream for
his skin problem due to no veterinarian care. It needs to be
applied 2xday, please. This is only a temporary treatment and the
animal needs to be examined by a vet please.
were some animals that were so old, they could hardly walk. Their
quality of life should be evaluated by a veterinarian. Their cages
are too small, very hot and empty. Hay was placed into all cages.
Keepers were shown to feed hooves and skulls as enrichment.
Suggestions: The hyenas should get bones and hooves (besides their
meat) at least 1xweek.
the exception of one of the solitary lions, all animals were kept
in empty cages and on tile floors. In one cage there was a huge
pride kept, while in two separate cages there were two solitary
Suggestions: Lions live in prides in nature and therefore are very
social animals. Some of the females could be taken out of the
group and introduced to the single males. Cage bottoms need to be
broken off and (as Mr. Lamine suggested) planted with grass.
supply for animals
cages only had concrete containers that are not cleaned well or
often. Some animals only get a drink from water bottles maybe
twice a day in this high temperature climate, and have no access
to water at all from late afternoon till next morning. The
chimpanzees learned to ask the visitors to fill their empty
bottles but other animals cannot do the same. Lots of waterers had
no plugs and held no water at all. Animals often only could lick
the wet concrete/tile floor after rain. Please view following
video-chimpanzee drinking from water bottle.
Suggestion: All animals need to have access to drinking water 24
hours a day from automatic waterers and proper furniture. Please

partially covered to provide some choices for the animals.
problems of carnivores. Most carnivores have
only partial ears left due to flies, their ears are continuously
bleeding and infected. Immediate medical care is required please.
carnivores seem to have missing teeth or possible teeth problems.
Some lions were very skinny due to not being to able to chew well
anymore and others taking their food.
Suggestions: Animals need to be examined by a vet please.
Continuing to keep animals off of hard/ cold/ wet/ dry, unyielding
surfaces (concrete, tile, wood floor, etc.) would be desirable.
The use of appropriate substrate (inside- paper products,
hay, straw, etc.; outside- nonflammable materials such as
sand, soil, mulch, fresh browse, etc.) will make a significant
difference not only in the animals’ health but would improve the
aesthetics of the exhibits. The substrate presentation that
was given to all staff is available for the zoo’s convenience in
Baboon playing in new sand:
The zoo has large amount of edible vegetation available on grounds
that could provide fresh, leafy branches (browse) at least every
2-3 days but if possible, every day. As mentioned during our
meetings, the zoo could start planting edible trees, bushes
and even crops inside and outside of exhibits, along visitor
pathways and resting areas that will provide future browsing
materials for growing collection demands. Whether cut by staff or
available by natural damage, fallen vegetation can be used rather
than wasted. A step by step instruction (made by our
horticulturist Hassena Kassim) regarding how to trim trees
properly is attached.
Suggestions: in order to supply browse the zoo needs to have plant
cutting tools such as:
pruners: for small branches about 1cm in diameter
branches up to 5cm in diameter
Saw: branches up to 17.5cm in diameter
and Small Branches: up to 6 meters reach and 5cm or
less in diameter branches
All animals that are social by nature should be paired up with
their conspecifics. Special
attention needs to be paid to social housing of great apes and
other primates. Please see attached document regarding laws and
regulations for social housing of primates. If animals are
confiscated, they should immediately be introduced into social
groups and an effort to return animals (if from foreign
countries) to their original country should be attempted.
Position for diet preparation.
animals (especially in small, unnatural environments) need to be
fed in a way that their foraging time is extended and proper
species-specific behaviors are encouraged. Browse needs to be cut
and distributed as well as all food needs to be chopped. If no
one can be appointed for this position, staff can be scheduled on
a rotation basis.
schedule and routine
The keepers seem to be without a daily routine. They were coming in
at different times; sometimes they cleaned exhibits, but sometimes
they did not; they feed randomly; and the animals never seem to
have clean water vessels or cages. It would be desirable to lay
down a set working routine as in most zoos with set hours and a
schedule for daily routine (morning cleaning, feeding, watering,
cleaning ponds, browse and substrates; afternoon checking the
drinking water vessels again, offering toys, preparing enrichment
for next day and doing extended workload, etc.).
- Extended workload.
I have observed many keepers sitting around and talking for
long periods of time. Instead, keepers could rebuild the empty
cages, add appropriate furniture, cut browse, plant gardens
(corn, banana, sugar cane and other usable plants), provide
enrichment, train their animals for basic medical and
husbandry behaviors, plant edible trees inside/outside the
exhibits for future use and shade, plant grass, paint the
walls of exhibits and night houses, clean the zoo daily and
monitor the visitors' behaviors by telling them not to throw
away garbage, cigarette butts, etc. They should answer the
visitors' questions, talking about their animals' ages, names,
behaviors, etc. so the visitors would start learning about
(during the day time) should be incorporated into the staff's
daily routine. The zoo has practically
no garbage cans. Local companies can be contacted for donation of
plastic and/or metal kegs and they could be distributed all over
area and storage place. The zoo had no commissary
to prepare food. There was one storage room for dry bread and a
very small room for seeds; otherwise there was no food on grounds.
Many food items were purchased with the Ambassador’s money
(fresh fruit, vegetables, milk, bread, fruit juice, cat chow,
etc.), as well as measuring cups or scoops to help keepers
distributing diet. Food was cut with machetes, only one keeper had

table, some chairs and additional kitchen supplies.
