The chital or cheetal (Axis axis), also known as chital deer, spotted deer or axis deer is a deer which commonly inhabits wooded regions of Sri Lanka, Nepal, Bangladesh, Bhutan, India, and in small numbers in Pakistan. It is the most common deer species in Indian forests. It has been introduced to Queensland, Australia, Chile, Argentina, Uruguay, Point Reyes National Seashore near San Francisco, California, Texas and Florida as well as Hawaii in the United States and to the Veliki Brijun Island in the Brijuni Archipelago of the Istrian Peninsula in Croatia.

The chital's coat is reddish fawn, marked with white spots, and its underparts are white. Its antlers, which it sheds annually, are usually three-pronged and curve in a lyre shape and may extend to 75 cm (2.5 ft). It stands about 90 cm (3 ft) tall at the shoulder and masses about 85 kg (187 lb). Its lifespan is around 20–30 years.

The spotted deer is found in large numbers in dense deciduous or semi-evergreen jungles and open grasslands. The highest numbers of Chital are found in the jungles of India where they feed upon tall grass and shrubs. Chital has been also spotted in Phibsoo wildlife Sanctuary in Bhutan which is the only remaining natural Sal (Shorea robusta) forests in the country. They do not occur at higher elevation forests where they are usually replaced by other species such as the Sambar deer. They also prefer heavy forest cover for shade and are intolerant of direct sunlight.

Chital are primarily grazers and feed on short, sprouting grasses. However they will also browse as well as eat forbs, fruit and branches of trees, especially when they are thrown down by monkeys. Stags, more than hinds, will stand on their hind legs on feed on tree foliage. Chital also eat their shed antlers as a source of nutrients and will use mineral licks. Chital prefer to be near water and will drink mornings and evenings in hot weather. Predators of the chital include tigers, leopards, dholes and mugger crocodiles. Red foxes also sometimes prey on chital fawns. Hinds and fawns are more likely to be victims of predation than adult stags and dholes are more successful in catching stags than tigers and leopards.

An interesting relationship has been observed between herds of axis deer and troops of the Northern Plains Gray Langur (Presbytis entellus), a widespread leaf-eating monkey taxon of South Asia. Axis deer apparently benefit from the langurs' good eyesight and ability to post a lookout in a treetop, helping to raise the alarm when a predator approaches. For the langurs' part, the axis deer's superior sense of smell would seem to assist in early predator warning, and it is common to see langurs foraging on the ground in the presence of axis deer. The axis deer also benefit from fruits dropped by the langurs from trees such as Terminalia bellerica and Phyllanthus emblica. Alarm calls of either species can be indicative of the presence of a predator such as a tiger.

The Axis Deer can be found in the Asian hoofstock collection at the Montgomery Zoo.

The Banteng (Bos javanicus), also known as Tembadau, is a species of wild cattle found in Southeast Asia. Banteng have been domesticated in several places in Southeast Asia, and there are around 1.5 million domestic banteng, which are called Bali cattle. These animals are used as working animals, and for their meat. Bali cattle have also been introduced to Northern Australia, where they have established stable feral populations.

The banteng is similar in size to domestic cattle, being 1.55 to 1.65 m (61 to 65 in) tall at the shoulder, and weighing 600 to 800 kg (1,300 to 1,800 lb). It exhibits sexual dimorphism, allowing the sexes to be readily distinguished by color and size. In mature males, the short-haired coat is blue-black or dark chestnut in color, while in females and young it is chestnut, with a dark dorsal stripe. Both males and females have white stockings on their lower legs, a white rump, a white muzzle, and white spots above the eyes. The build is similar to that of domestic cattle, but with a rather slender neck and small head, and a ridge on the back above the shoulders. The horns of females are short and tightly curved, pointing inward at the tips, and those of males arc upwards, growing 60 to 75 cm (24 to 30 in) long, and being connected by a horn-like bald patch on the forehead.

Banteng live in sparse forest where they feed on grasses, bamboo, fruit, leaves and young branches. The banteng is generally active both night and day, but in places where humans are common they adopt a nocturnal schedule. Banteng tend to gather in herds of two to thirty members.

The Banteng can be found in the Asian hoofstock collection at the Montgomery Zoo. 

The Black Swan (Cygnus atratus) is a large waterbird which breeds mainly in the southeast and southwest regions of Australia.

Black Swans were first seen by Europeans in 1697, when Willem de Vlamingh's expedition explored the Swan River, Western Australia.

The Black Swan was described scientifically by English naturalist John Latham in 1790. It was formerly placed into a monotypic genus, Chenopis.

The common name 'swan' is a gender neutral term, but 'cob' for a male and 'pen' for a female are also used, as is 'cygnet' for the young. Collective nouns include a 'bank' (on the ground) and a 'wedge' (in flight). Black Swans can be found singly, or in loose companies numbering into the hundreds or even thousands.

Black Swans are primarily black-feathered birds, with white flight feathers. The bill is bright red, with a pale bar and tip; and legs and feet are greyish-black. Cobs (males) are slightly larger than pens (females), with a longer and straighter bill. Cygnets (immature birds) are a greyish-brown with pale-edged feathers.

A mature Black Swan measures between 110 and 142 cm (43-56 in) in length and weighs 3.7–9 kg (8.1-20 lbs). Its wing span is between 1.6 and 2 meters (5.3-6.5 ft). The neck is long (relatively the longest neck among the swans) and curved in an "S"-shape.

The Black Swan utters a musical and far reaching bugle-like sound, called either on the water or in flight, as well as a range of softer crooning notes. It can also whistle, especially when disturbed while breeding and nesting.

The Black Swan is unlike any other Australian bird, although in poor light and at long range it may be confused with a Magpie Goose in flight. However, the Black Swan can be distinguished by its much longer neck and slower wing beat.

The Black Swan is common in the wetlands of south western and eastern Australia and adjacent coastal islands. In the south west the range encompasses an area between North West Cape, Cape Leeuwin and Eucla; while in the east it covers are large region bounded by the Atherton Tableland, the Eyre Peninsula and Tasmania, with the Murray Darling Basin supporting very large populations of Black Swans.  It is uncommon in central and northern Australia.

The Black Swan's preferred habitat extends across fresh, brackish and salt water lakes, swamps and rivers with underwater and emergent vegetation for food and nesting materials. Permanent wetlands are preferred, including ornamental lakes, but Black Swans can also be found in flooded pastures and tidal mudflats, and occasionally on the open sea near islands or the shore.

Black Swans were once thought to be sedentary, but the species is now known to be highly nomadic. There is no set migratory pattern, but rather opportunistic responses to either rainfall or drought. In high rainfall years, emigration occurs from the south west and south east into the interior, with a reverse immigration to these heartlands in drier years. When rain does fall in the arid central regions, Black Swans will migrate to these areas to nest and raise their young. However, should dry conditions return before the young have been raised, the adult birds will abandon the nests and their eggs or cygnets and return to wetter areas.

Black Swans, like many other water fowl, lose all their flight feathers at once when they moult after breeding, and they are unable to fly for about a month. During this time they will usually settle on large, open waters for safety.

Black swans can be found in the ponds located in the Australian realm of the Montgomery Zoo. 

The Indian Rhinoceros (Rhinoceros unicornis) is also called Greater One-horned Rhinoceros and Asian One-horned Rhinoceros and belongs to the Rhinocerotidae family. Listed as a vulnerable species, the large mammal is primarily found in parts of north-eastern India and in protected areas in the Terai of Nepal, where populations are confined to the riverine grasslands in the foothills of the Himalayas. Weighing between 2260 kg and 3000 kg, it is the fourth largest land animal and has a single horn, which measures 20 cm to 57 cm in length.

These Rhinoceros once ranged throughout the entire stretch of the Indo-Gangetic Plain but excessive hunting reduced their natural habitat drastically. Today, about 3,000 Rhinos live in the wild, 2,000 of which are found in India's Assam alone.

These Rhinoceros can run at speeds of up to 55 km/h (34 mph) for short periods of time and is also an excellent swimmer. It has excellent senses of hearing and smell but relatively poor eyesight.

These rhinos live in tall grasslands and riverine forests but due to habitat loss they have been forced into more cultivated land. They are mostly solitary creatures, with the exception of mothers and calves and breeding pairs, although they sometimes congregate at bathing areas. They have home ranges, the home ranges of males being usually 2-8 square kilometers in size, and overlapping each other. Dominant males tolerate males passing through their territory except when they are in mating season, when dangerous fights break out. They are active at night and early morning. They spend the middle of the day wallowing in lakes, rivers, ponds, and puddles to cool down. They are extremely good swimmers. Over 10 distinct vocalizations have been recorded.

Nepali and Indian rhinos have few natural enemies, except for tigers. Tigers sometimes kill unguarded calves, but adult rhinos are less vulnerable due to their size. Humans are the only other animal threat, hunting the rhinoceros primarily for sport or for the use of its horn. Mynahs and egrets both eat invertebrates from the rhino's skin and around its feet. Tabanus flies, a type of horse-fly are known to bite rhinos. The rhinos are also vulnerable to diseases spread by parasites such as leeches, ticks and nematodes. Anthrax and the blood-disease septicemia are known to occur.

The Greater Indian Rhino can be seen in the Asian realm at the Montgomery Zoo.

The Reeves' Muntjac (Muntiacus reevesi) is a muntjac species found widely in southeastern China (Gansu to Yunnan) and in Taiwan. They have also been introduced in the Netherlands, south England, the Midlands, east Wales and more recently in Ireland. It feeds on herbs, blossoms, grasses and nuts, and was also reported to eat trees.  It takes its name from John Reeves, who was appointed Assistant Inspector of Tea for the British East India Company in 1812.

This muntjac grows to 0.95 m (37 inches) in length, and weighs between 10 and 18 kg (22-40 pounds) when fully grown. The male has short antlers, usually four inches or less, and uses them to push enemies off balance so he can wound them with his upper two inch canine teeth. The Taiwanse subspecies (M. r. micrurus), commonly known as the Formosan Reeves' Muntjac, is relatively dark compared to the other subspecies.

The Reeves' Muntjac is also called the barking deer, known for its distinctive bark, though this name is also used for the other species of muntjacs.

An unspecified species of muntjac was introduced to the grounds of Woburn Abbey in Bedfordshire in the nineteenth century by the then Duke of Bedford. While a small number are reported as escaping, it is extremely unlikely that they are the source of the current UK population. Larger numbers of muntjac escaped from Whipsnade Zoo, and they are the more likely ancestors, in addition to other releases.

Since the Wildlife and Countryside Act 1981, it has been illegal to release the species except where already established. Reeves' Muntjac colonies exist throughout England south of Derbyshire, and the population continues to grow. Small groupings of muntjacs have been seen in large urban parks in the Islington, Highgate, East Ham, Finchley and Greenwich areas of London, cemeteries, parks (seen in Green Park nr M4), and schools (Crosfields School) in the Reading area, the Headington Hill area outside of Oxford, Letchworth in Hertfordshire, Epping Forest in Essex, and in Warwickshire and Birmingham.

Muntjac deer can be something of a traffic hazard, as they do not readily move out of the way of cars.

The Reeve’s Muntjac can be found on display in the Asian realm at the Montgomery Zoo.

Sumatran tiger (Panthera tigris sumatrae) is a subspecies of tiger found on the Indonesian island of Sumatra. Recent genetic testing has revealed the presence of unique genetic markers, which isolate Sumatran tigers from all mainland subspecies. About 400-500 wild Sumatran tigers were believed to exist in 1998, but their numbers have continued to decline.

The Sumatran Tiger is the smallest of all surviving tiger subspecies. Male Sumatran tigers average 204 cm (6 feet, 8 inches) in length from head to tail and weigh about 136 kg (300 lb). Females average 198 cm (6 feet, 6 inches) in length and weigh about 91 kg (200 lb). Its stripes are narrower than other subspecies of tigers' stripes, and it has a more bearded and maned appearance, especially the males. Its small size makes it easier to move through dense rain forests. It has webbing between its toes that, when spread, makes Sumatran tigers very fast swimmers. It has been known to drive hoofed prey into the water, especially if the prey animal is a slow swimmer.

Sumatran Tigers commonly prey on larger ungulates, like Wild Boar, Malayan Tapir and deer, and sometimes also smaller animals, like fowl, monkeys and fish.  Orangutans could be prey, but since they spend a minimal amount of time on the ground, tigers rarely catch one. Sumatran tigers will sometimes prey upon mice and other small mammals when larger prey is scarce.

The Sumatran Tiger may be viewed in the Asian realm at the Montgomery Zoo.
