Overview
The tiger (Panthera tigris) is one of the largest and most iconic of the world’s big cats. Known for their power and grace, these predominantly solitary animals are renowned for their striking coat pattern, featuring a base orange coloration with bold black stripes that varies among individuals and subspecies. Tigers are apex predators, playing a crucial role in the ecosystems they inhabit by controlling populations of herbivores and thereby maintaining the balance between prey herbivores and the vegetation upon which they feed.
Tigers are native to various parts of Asia and once ranged widely across the continent. However, over the last century, their habitat has been dramatically reduced due to human activities. Tigers now inhabit a fraction of their former range, with many populations isolated within small pockets of suitable habitat within predominantly human-dominated landscapes. Despite their reduced range, tigers exhibit significant adaptability and can thrive in various environments, including grasslands, mixed grassland forests, deciduous forests, and mangrove swamps.
Across their range, tigers face numerous threats, including habitat loss, reduction in prey availability, and direct killing due to conflict with humans or illegal poaching for their body parts, which are used in traditional medicines. The tiger is now listed as endangered by the International Union for Conservation of Nature (IUCN), and global conservation efforts are focused on preventing further population declines and habitat loss and reducing human-tiger conflict.

Physical Description:
Tigers are known for their striking coat pattern, each boasting a unique pattern of bold black stripes against an orange coat. The underside of the belly and the interior limbs are white. Tigers have a muscular body with a notably strong and heavy build. They possess a round head, large forelimbs, and long, retractable claws that aid hunting and climbing.
Tigers vary in size depending on their subspecies, with the largest tigers found in Siberia and the smallest in the islands of Sumatra. Males are generally larger and heavier than females, with a more pronounced ruff or mane around the neck. Their eyes are yellow to amber in color, and they have a white spot on the back of each ear, speculated to function as a visual cue in communication.

Native Habitat:
Tigers are remarkably adaptable, capable of living in diverse environments, from the icy cold of the Russian Far East to the humid mangrove swamps of the Sundarbans. They can also thrive in grasslands and both deciduous and evergreen forests. Their adaptability is a testament to their versatility, with Amur tigers developing a layer of fat and a longer coat for cold climates. In contrast, tigers in the hot Sundarbans have become adept swimmers to hunt and cool off.
Regardless of the environment, tigers have certain requirements that must be met. A reliable water source is critical for hydration because tigers enjoy bathing, particularly in hotter climates. The environment must also provide ample cover for hunting, as tigers are ambush predators and rely heavily on stealth to catch their prey.
The most crucial requirement, however, is a large prey base, with a preference for large ungulates. This need often dictates the environments tigers inhabit, as they require environments that support healthy populations of these prey animals. Despite their ecological flexibility, habitat destruction, and fragmentation threaten their survival, emphasizing the need for conservation efforts focused on preserving their diverse habitats.

Diet & Feeding Habits:
Tigers are obligate carnivores, primarily feeding on a variety of mammalian prey. They prefer large ungulates such as sambar deer, wild boar, water buffalo, and gaur but will also eat smaller prey like hares, peafowl, or monkeys when larger prey is scarce. Tigers are opportunistic predators known to consume carrion in times of scarcity.
Tigers typically hunt alone, using their distinctive striped coat as camouflage to stalk and ambush their prey. They rely on a blend of stealth and powerful physical attributes, including strong jaws and retractable claws, to bring down their prey. A successful hunt can provide enough food for several days, during which the tiger will remain with its kill and feed intermittently.
Mating Behavior:
Mating Description:
The mating system of tigers is polygynous, with males often mating with several females. Courtship involves a series of vocalizations, scent marking, and a peculiar behavior known as the “Flehmen response,” where the male assesses the female’s reproductive status by smelling her urine or genital area.
The mating process is usually initiated by the female, who makes loud vocalizations to signal her availability to males. Once a male has been attracted, the pair engages in copulation several times over a few days. Aggressive behavior can be observed during copulation, with the male often biting the back of the female’s neck.

Social Structure Description:
Tigers are predominantly solitary animals, with individuals maintaining exclusive territories or home ranges. They are highly territorial and use a complex system of vocal, chemical, and visual signals to communicate with each other and establish territories. Male territories often overlap with those of several females, but males actively avoid each other.
While solitary, tigers are not entirely antisocial. They have been observed to share kills, and females with cubs often form small groups. During the mating season, males and females temporarily pair up.

Population Trend:
Wild tiger populations have undergone a drastic decline over the past century. Once numbering in the hundreds of thousands, today’s wild tiger population is estimated to be around 3,900. This steep drop is largely due to habitat loss from deforestation and urban expansion. As human populations grow and spread, natural habitats are transformed for agriculture, infrastructure, and housing, fragmenting the once vast territories of the tigers. The fragmentation decreases the available space for tigers and disrupts their access to prey, often forcing them to venture into human-dominated landscapes.
In addition to habitat loss, poaching is a significant threat to wild tiger populations. Tiger parts, from their bones to their skin, are highly valued in illegal wildlife markets for use in traditional medicine and as status symbols. Even though international trade in tiger parts is prohibited under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), enforcement of these regulations can be challenging in many parts of the tiger’s range. Human-tiger conflict also poses a threat, as encroaching human activities can lead to deadly encounters, often resulting in the killing of tigers in retaliation or to prevent future conflicts.
In contrast to the precarious situation in the wild, tigers are popular in zoos worldwide. Zoos play a vital role in raising awareness about tigers’ plight and funding conservation initiatives. Additionally, many zoos participate in captive breeding programs, which aim to maintain the genetic diversity of the tiger population. These programs can be a potential source for reintroduction efforts to bolster wild populations. However, reintroduction is complex and requires the presence of suitable habitats and adequate prey and measures to minimize human-tiger conflicts. Therefore, while captive populations are crucial, they cannot replace the need for conserving tigers in their natural habitats.
Population Threats:
Tigers face numerous threats that have led to their endangered status. Habitat loss due to deforestation and human development has led to a drastic reduction in their range. Poaching for their fur and body parts, highly valued in traditional medicine and decoration, poses a significant threat.
Human-wildlife conflict is another major issue. As human populations expand and encroach into tiger habitats, encounters, and conflicts are more frequent, often resulting in the killing of the tigers.
Conservation Efforts:
Multiple conservation organizations, such as the World Wildlife Fund (WWF) and Panthera, along with governments of countries where tigers are native, are engaged in conservation efforts. These include anti-poaching initiatives, habitat preservation and restoration, and community education and outreach programs.
International and national laws also aim to protect tigers from hunting and trade. The Global Tiger Initiative, launched in 2010, aims to double the number of wild tigers through a combination of efforts from 13 tiger range countries.
