was separated from his two females, because he never learned
how to breed. Therefore, a breeding male, Yamamoto, was
brought in and introduced to the females. Although the three
of them got along well, the females were very much missing
Dongdong. They were constantly trying to see what he was
doing through the shifting tunnel window bars. Dongdong was
also extremely stressed out, constantly trying to establish
visual contact with everybody, displaying a lot and had
frequent redirected aggression towards furniture items

was there for a five year loan program. To best remedy the
situation, it was suggested that each male should have a
female at all times and the
females would be altered weekly between the males. No. 1 was
reintroduced to Dongdong immediately. This change not only
resolved Dongdong’s situation, but also provides a better
chance for the females to be able to socialize with both
males, as well as improves the chance for them to learn how

soil and some climbing structures. I was very pleased to see
that the night houses were extremely large with suitable
climbing structures. Resting places had no soft materials

is preferable to add more windows and/or skylights to
increase light. It would also be advantageous to build double
sliding doors (one being solid and the other one built
from bars and mesh) so that the night houses and the exhibit
could be connected with a “Round Robin” system,
allowing animals to move about in circular ways and not just
a linear fashion. This system could be used for all other
species as well and would help with introductions or with
shifting animals more easily and quickly.
can be allowed outside for limited time during the winter;
however, they need to have access to inside heat and
provided with extra blankets. Some institutions keep to a
temperature guideline and will only let their chimpanzees
out if the temperature reaches 10-13 C, while others, such
as Chimpanzee Sanctuary Northwest, USA, allow the
chimpanzees to make their own decision. It is important to
remember to provide chimpanzees the opportunity to seek
warmth if allowed outdoor access during cold weather, and
there might be a temperature so low that outdoor access is
only time they don't allow them outside is when heavy, wet
snow reduces the voltage on their electric fence.

males (6 years and older) may be housed alone, but not in
complete isolation. Opportunities for tactile, olfactory,
visual and/or auditory interaction with other elephants must
be provided (Rasmussen et al. 1982). Each institution must
be able to demonstrate and/or describe how they will
successfully isolate and socialize males. In the wild, adult
males are primarily solitary. However, they do have regular
contact with other elephants.
access and temperature: Institutions
should consider designing exhibits that allow elephants outdoor
access as much as possible – weather, health, and
safety permitting. Elephants exposed to temperatures
below 40°F (5°C) for longer than 60 minutes, must be
monitored hourly to assess the potential for hypothermia. If
needed to prevent hypothermia, supplemental heat, an area of
direct sunlight protected from wind/precipitation, access to
indoor barn stalls or other options for thermal management
must be provided for the elephants.
– Outdoor – Nighttime: Elephants
kept outdoors overnight when temperatures are under 40°F (5°C),
must be provided with supplementary heat and adequate
shelter from adverse weather.
Suggestions for Elephant Care
needs to be added both inside the night house and on the
exhibit at a depth of one meter.
Elephants cannot be kept on concrete. It is very hard on
their feet and joints and causes severe medical problems.
Besides sand covering the floor, the elephants need a larger
pile of sand (approximately 2 meters high) to lie
The animals should have continuous free access to
food by using feeder devices (food placed inside metal kegs
with holes, hay bags, etc.) and mostly from up high.
bags can be woven from ropes. The nets from International
Cordage are made
specifically for elephants. The zoo must contact the company
for details about rope, size, etc. The Phoenix Zoo
was the first zoo to incorporate the nets; however our nets
are prototypes. http://www.international-cordage.net/
Elephants need to receive large EDIBLE tree branches
every day (please see
attached browse list for elephants).
The elephants should no longer be chained and picture
taking should be discontinued or at least reduced.
Tires can be hung from chains as enrichment.
Scratching posts made from
palm trees can be chained or secured in a
safe way to the fence or the poles.
tree logs (whole trees) can
be laid all over the ground to encourage the animals to step
over and/or go
around them, allowing
for added exercise.
Clay wallow can
help with proper skin care and prevent sunburn.

Houses, Off-exhibit Areas and Correct Substrate Use
hoof stock and some cats were kept in large or even
luxurious exhibits, many animals (mostly carnivores, birds,
pigs and primates) were housed on sterile surfaces close to
freezing temperature with reduced
chance for exploratory behaviours. This practice likely
originates out of good intent to keep a clean environment
for the animals, as it appears to be a cultural inheritance
that if an exhibit is not hosed frequently, than the animals
are not being well cared for. However, this practice creates
poor conditions for the animals.
keeping animals off of unyielding surfaces (brick, concrete,
etc.). The use of appropriate substrate (inside- paper
products, hay or straw, etc.; outside- nonflammable
materials such as grass, sand, soil, mulch, fresh browse,
etc.) will make a significant difference not only in the
animals’ mental and physical health, but also in the
improvement of the exhibit aesthetics. Using substrate will
reduce cleaning time and water consumption, as well.
Soaking, scrubbing and hosing dry waste takes much longer
than spot cleaning substrate due to the substrate’s
ability to absorb urine and cover fecal matter. Reducing
hosing and partially covering surface with substrate will
overcome any of these obstacles and provide animals with a
House Conditions and Debris in Exhibits and Visitor Pathways
Chairs, dollies and cardboard boxes should not be stored in
night houses with animals. Chipping paint should be scrubbed
off and the walls should be repainted. Garbage needs to be
removed from public ways. These problems can create
safety issues as well as making the exhibits look dirty and
primate species were kept on bare concrete and also in
solitary confinement without any visual or tactile
opportunities with other primates. Social isolation and reduced space allowance have been
documented to cause increased levels of aggression and
stress levels in a range of captive wild animals from
primates to dolphins.

primates, even if it is a different species, until they are
paired up with their conspecific. Please review laws and

"The social needs of animals used in research,
teaching, or testing, should be given equal consideration
with environmental factors such as lighting, heating,
ventilations and containment (caging). Particularly in the
case of singly housed animals, daily observation provides an
alternative from of social contact for the animal and
commonly facilitates handling in that the animal becomes
accustomed to the human presence. .. Most animals should not be housed singly unless required by medical
condition, aggression, or dictates of the study. Singly
housed animals should have some degree of social contact
with others of their own kind. ... In the interest of
well-being, a social environment is desired for each animal
which will allow basic social contacts and positive social
relationships. Social behaviour assists animals to cope with
circumstances of confinement."

" A compatible conspecific probably provides more
appropriate stimulation to a captive primate than any other
potential environmental enrichment factor. ... Monkeys
should, unless there are compelling reasons for not doing
so, be housed socially. ... Young monkey should not
normally be separated from its mother at an early age (i.e.,
at 3-6 months) but should remain in contact for one year to
18 months, in most species. There is unlikely to be any
greater productivity through early weaning, in seasonally
breeding species, such as rhesus monkeys. Even in
non-seasonal breeders, any slight increase in productivity
must be offset against the resulting behavioural
abnormalities of the offspring."

"Social interactions are considered to be one of the
most important factors influencing the psychological
well-being of most nonhuman primates. ... The common
practice of housing rhesus monkeys singly calls for special
attention [p. 99] ... Every
effort should be made to house these [singly caged] animals
socially (in groups or pairs), but when this is not
possible, the need for single housing should be documented
by investigators and approved by the IACUC. ... The animal

support of primates, particularly animals that are singly
zoo has a large amount of edible vegetation available on
grounds that can provide fresh, leafy branches (browse).
Suggestions: Browse should be provided at least every 2-3 days,
but if possible, every day for animals that need it. The zoo
would benefit by planting edible trees, bushes and
even crops inside and outside of exhibits and along visitor
pathways. The bushes can provide future browsing materials
for growing collection demands. Whether cut by staff or
available by natural damage, fallen vegetation of approved
browse plants can be used rather than wasted.
Mixed species exhibits can be created in order to free up
space and create a more esthetic, complex exhibit. This will
also immediately resolve some of the solitary (otherwise
social) species problems until they are paired up with their
conspecific. Please review some photos of Phoenix Zoo
All animals need to be fed in a way that extends their
foraging time and encourages appropriate, species-specific
behaviors. If no one can be appointed for this position,
staff can be scheduled to cut browse and chop diet on a
were often observed smoking, some of them inside the night
houses right next to the animals.
Suggestions: The zoo should change its smoking policy. The
first step can be creating designated smoking areas
(tables, chairs, ashtrays, garbage cans) for visitors,
directing them to these areas to smoke. Keepers should no
longer smoke in front of the visitors at all and should
absolutely not smoke inside the animals' night houses and/or
next to the animals. Keepers also need to have
designated smoking areas behind the scenes, out of the
animals from conspecifics and hand-rearing them for
performances compromises welfare, causes a lack of social
behaviors, aggression, depression, health problems and more.
Performances cause suffering to thousands of animals and “provide a
message that it is okay to use/abuse animals for
entertainment and demonstrates that the animals can only be
“controlled” by pain and fear” (Neale 2013).
removal of teeth and physical abuse that animals are
subjected to during circus-type performances are well-known
practices around the world and result in a higher percentage of inactivity and/or increased
abnormal behaviour; i.e. self-injury and stereotypies.
lack of appropriate social interaction, reduction in time
spent foraging and the restricted freedom to perform many
highly motivated behaviours represent stressors for circus
animals. Stress can have short-term as well as chronic
long-term negative behavioural and physiological effects.
Over time this can induce poor welfare by compromising
health, altering brain function and lowering life
In October 2011, Ministry of Rural and Urban Housing Development issued a
directive banning animal performances in traditional zoos. Nanjing, Kunming, Shanghai, Chongqing, Zhengzhou, Jinan and Chengdu have
all closed down their animal performances (Neale 2013).
Suggestions: Ending the circus-style animal performances
and using current performing animals as ambassadors for
their wild counterparts to promote species conservation and
protection, as well as improving their housing
circumstances, will demonstrate a public commitment to
protecting the natural environment, protecting animals from
suffering and protecting species from extinction.

Lack of Substrate Use in Zoos addresses
the easy fix of empty cages and shows how much benefit there
is to animals’ lives when provided with substrate; i.e.,
when they do not have to sit inside of empty concrete cages.
This is probably the most important animal welfare
presentation to give out of the four.

ways as they would in the wild, instead of eating in short
periods of time from metal dishes or rubber tubs.
