Purple Sunbird
Cinnyris asiaticus
Common sights across the plains, gardens, and scrub forests of the peninsula
Early mornings over the scrub forests of the Amrabad Tiger Reserve provide a fantastic opportunity to study a tiny bird with iridescent feathers.
High on the skeletal branch of a teak tree, a tiny silhouette shakes off the dawn chill. As the first ray of the Telangana sun cuts through the canopy, the drab, dark bird suddenly transforms. It erupts into an electric shimmer of metallic blues, deep purples, and glossy blacks. This is the male Purple Sunbird (Cinnyris asiaticus), a living gemstone of the Indian subcontinent.
From the wild, deciduous expanses of Amrabad to the bustling, urban wetlands of Hyderabad—like Ameenpur Lake and the suburban oasis of Kudikunta Lake—this resilient avian wanderer navigates a changing world. This is the story of its life, its identity, and its struggle against a vanishing landscape.
Located in the central stretch of the Deccan Plateau, Telangana has sub-tropical climate and the terrain consists mostly of hills, mountain ranges, and thick dense forests covering an area of 27,292 km². The annual rainfall ranges between 1,100 mm to 1,200 mm and the annual temperature varies from 15°C to 45°C. The State is drained by a number of rivers which include Godavari and Krishna.
Telangana is endowed with rich diversity of flora and fauna. It has dense teak forests on the northern part along the banks of river Godavari. As per the Champion & Seth Classification of Forest Types (1968), the forests in Telangana belong to three Forest Type groups, which are further divided into 12 Forest Types. The Telangana Ku Harita Haram initiative aims at achieving the twin objectives of increasing the forest cover and reduce pressure on the existing forest resources, through massive community participation by Vana Samrakshna Samithis (VSS) and Eco-Development Committees (EDCs) in Protected Areas and Watershed Development Committees in the Watershed areas. Recorded Forest Area (RFA) in the State is 26,904 km² of which 20,353 km² is Reserved Forest, 5,939 km² is Protected Forest and 612 km² is Unclassed Forests. In Telangana, during the period 1st January 2015 to 5th February 2019, a total of 9,420 hectares of forest land was diverted for non-forestry purposes under the Forest Conservation Act, 1980 (MoEF & CC, 2019). As per the information received from the State during that last two years, 12,730 ha of plantations including avenue plantations in the State.
Three National Parks and nine Wildlife Sanctuaries constitute the Protected Area network of the State covering 5.08% of its geographical area and it is part of the Eastern Ghats. The Nagarjunsagar-Srisailam Tiger Reserve, the largest tiger reserve in India spread over the five districts of Kurnool, Prakasam, Guntur, Nalgonda and Mahabub Nagar falls in its precincts.
Lakes and water bodies in Telangana are locally known as cheruvu, kunta & tanks. Quite a few of these lakes, like Tigal Kunta, Somajiguda Tank, Mir Jumla tank, Pahar Tigal Kunta, Kunta Bhawani Das, Nawab Saheb Kunta, Afzalsagar, Nallakunta, Masab Tank etc, have completely disappeared and the surface area of most of the surviving lakes have shrunk and turned into tiny ponds and cesspools. Lakes like the Hussain Sagar Lake, Kunta Mallaiyapalli have shrunk drastically. Of the thousands of water bodies existing in 1970s in various sizes in and around Hyderabad, today only about 70 to 500 of them have survived. Most of them have disappeared due to encroachment or have been illegally drained for real estate projects by private or government agencies. The existing lakes have been used to dump garbage and sewage water. The Kudikunta Lake a recently restored lake which will, hopefully, in the next few years recover and regain its lost avian population.
Most of these lakes and tanks around Hyderabad were built during the regime of the Qutb Shahis in 16th and 17th century and later by the Nizams as sources of drinking water for the residents of Hyderabad. The area of Hussain Sagar, which is the largest lake in Hyderabad shrunk by more than 40% i.e. from 550 ha to 349 ha in just 30 years. This lake was built in 1575 AD and since 1930 is not being used as a source for drinking water. Another such lake is the Ameenpur Lake on the western fringe of Hyderabad, surrounded by fantastic primordial rock formations, modern apartments, factories and a village. Ameenpur Lake is an ancient sprawling man-made lake dating back to the time of Ibrahim Qutb Shah, who ruled the kingdom of Golconda between 1550 and 1580. According to one account, the tank was excavated to irrigate a large public garden. The lake is now divided into two parts called Pedda Ameenpur and Chinna Cheruvu.
The birds you see here are from a number of varied locations and habitats like the Kudikunta Lake, Himayat Sagar Lake, Ammavaripeta Cheruvu, Bhigwan Bird Sanctuary and a few from lesser known locations like the Mallucheruvu deep within the Amrabad Tiger Reserve, Kantegaon Lake in Boath Buzurg and the city hotspots like the Ameenpur Lake, Kudikunta Lake and the Kistareddypet Lake.
Achampet Forest Range, Amrabad Tiger Reserve
The Amrabad Tiger Reserve (ATR), sprawling across the rugged Nallamala Hills of the Eastern Ghats in Telangana, stands as one of India’s largest and most ecologically significant wildernesses. Central to the administration, protection, and ecological preservation of this pristine landscape is the Achampet Forest Range. Operating under the Nagarkurnool forest division, the Achampet range serves as a vital sanctuary for the region’s apex predators, a crucial watershed, and a vibrant cultural landscape where nature and ancient indigenous traditions intertwine.
Geographically, the Achampet Forest Range is defined by its highly dramatic and punishing terrain. The landscape features elevated plateaus—most notably the Farahabad plateau—broken up by sheer cliffs, deep gorges, and steep, winding valleys. This fractured topography acts as a natural fortress, isolating the deep interior areas from intensive human disturbance. The range experiences a warm tropical climate, receiving the majority of its life-giving rainfall during the Southwest monsoon. Crucially, the complex network of seasonal and perennial streams weaving through Achampet’s valleys empties directly into the Krishna River basin, forming a critical catchment zone that feeds the massive Srisailam and Nagarjuna Sagar dams.
The vegetation of the Achampet range is dominated by tropical dry deciduous forests mixed with dense undergrowths of bamboo and tall native grasses. The canopy includes valuable and sturdy tree species like teak, sal, and acacia, alongside a vast repository of rare, endemic medicinal herbs traditionally preserved by the local Chenchu communities.
This dense floral mosaic supports a thriving wildlife population. The Achampet division, particularly around the high Farahabad plateau, holds a major portion of the Royal Bengal Tiger population within Telangana. Alongside the tiger, the range protects co-predators such as Indian Leopards, Sloth Bears, and packs of endangered Wild Dogs (Dholes). These carnivores track a robust prey base of herbivores, including Sambhar, Chital (spotted deer), Nilgai, and the elusive and shy Four-horned antelope (Chousingha).
Furthermore, the skies and canopies of Achampet host over 300 avian species, making it a vital regional stronghold for bird conservation.
The Achampet Forest Range is unique for its deep anthropological roots. It is the ancestral home of the Chenchu tribe, an indigenous group that has lived symbiotically within the Nallamala forests for centuries. The Chenchus possess deep traditional knowledge of the forest's ecology and work closely with forest authorities in conservation and anti-poaching operations. Mechanically tied to the landscape are also deep historical and spiritual landmarks. The range houses the ancient Uma Maheshwaram Temple, a historic stone shrine built on a cliffside that is traditionally revered as the northern gateway to the sacred pilgrimage site of Srisailam.
Preserving the wilderness of Achampet requires a delicate balancing act by the Telangana Forest Department. The range faces continuous anthropogenic pressures, including forest fires, the spread of invasive weeds like Lantana camara, and habitat fragmentation caused by state highways slicing through the reserve. To mitigate these pressures and provide a legal economy for the Chenchu people, authorities have promoted regulated eco-tourism. Controlled jungle safaris, community-run stays, and environmental education camps around Farahabad allow visitors to witness the raw beauty of Telangana's wild heart without disrupting its ecological balance. Through strict management and local partnership, the Achampet Forest Range remains a defensive shield for India's natural heritage.

Purple Sunbird
India is home to a stunningly diverse array of sunbird species, each adapted to the country's varied ecological zones. While the adaptable Purple Sunbird (Cinnyris asiaticus) and the vibrant Purple-rumped Sunbird (Leptocoma zeylonica) are common sights across the plains, gardens, and scrub forests of the peninsula, more specialized species thrive in unique geographical pockets. In the high-altitude forests and foothills of the Himalayas and Northeast India, one can spot the brilliant Crimson Sunbird (Aethopyga siparaja)—declared the national bird of Singapore but widely distributed in India—alongside the Green-tailed Sunbird (Aethopyga nipalensis) and the Fire-tailed Sunbird (Aethopyga ignicauda), which boast elongated, elegant tails and dazzling palettes of scarlet, yellow, and green. Down in the dense, humid rainforests of the Western Ghats, the endemic Vigors's Sunbird (Western Crimson Sunbird, Aethopyga vigorsii) and the Crimson-backed Sunbird (Small Sunbird, Leptocoma minima) dominate the canopy, the latter being one of the smallest birds in India. Additionally, the Loten's Sunbird (Cinnyris lotenius), with its exceptionally long, scythe-like bill, shares the southern peninsula's woodlands, completing a rich avian tapestry that makes India a true haven for these nectar-feeding jewels.
The name "Sunbird" is a direct nod to the bird's reliance on sunlight to reveal its true form. Without the sun, the bird looks dull and dark; under the sun, it radiates color. Its scientific name tells an explicit geographical story. The genus name Cinnyris originates from a Greek term used by ancient writers to describe a small, legendary bird. The specific epithet asiaticus means "of Asia," explicitly marking its vast distribution across the Asian continent. Locally in Telugu, it is often referred to generally as టేనెపిట్ట (Nectar Bird), a simple, accurate title for this tiny consumer of sweetness.
The Jewel of Telangana: From Amrabad to Hyderabad
In the rugged terrains of the Amrabad Tiger Reserve, the Purple Sunbird plays a vital role in the ecosystem. Here, amidst the undisturbed dry deciduous forest, it zips between wild blooms, acting as a chief pollinator. It shares this wilderness with apex predators, yet its survival depends on the seasonal flowering of native trees like the Flame of the Forest (Butea monosperma). However, the Purple Sunbird is remarkably adaptable. As the wilderness gives way to urbanization, the bird has carved out a life within the concrete grid of Hyderabad. At Ameenpur Lake—India’s first urban Biodiversity Heritage Site—the sunbirds occupy the thorny scrub fringes, darting between invasive Prosopis juliflora bushes and native acacias.
A few kilometres away, at Kudikunta Lake in Kondapur, the species showcases its urban grit. In a landscape hemmed in by high-rises and IT parks, the Purple Sunbird utilizes suburban gardens, household balconies, and manicured parks. If there is a tubular flower blooming, the sunbird will find it, proving that nature can persist even in the cracks of human development.
To understand the Purple Sunbird, one must look closely at its physical design, which represents a masterclass in avian evolution. The Purple Sunbird is a minuscule creature measuring 10 to 11 centimetres from beak to tail and weighing a mere 8 to 11 grams. It has a long, slender, and distinctly down-curved (decurved). This structural adaptation allows it to reach deep into the corolla tubes of flowers to extract nectar with a tongue that is tubular and brush-tipped, acting like a high-speed straw.
The most striking feature of the Purple Sunbird is its seasonal transformation. During the spring breeding season, the male appears completely black from a distance. However, under direct sunlight, its feathers refract light to reveal an intense, iridescent metallic purple, dark blue, and emerald green sheen. Concealed beneath its wings are brilliant pectoral tufts of bright yellow and scarlet, flashed exclusively during courtship displays. After the breeding season, the male sheds this royal coat. It adopts an "eclipse" plumage, becoming olive-brown above and yellow below, retaining only a dark, iridescent blue-black stripe running down the centre of its throat and breast (the "throat-stripe"). The female remains cryptically coloured year-round to avoid predators while nesting. She features an olive-green or brown back, a pale yellow underside, and a faint supercilium (eyebrow stripe) above a dark eye line.
In Telangana, India, and across Asia, the Purple Sunbird shares its territory with several relatives. Distinguishing them requires a sharp eye.

Regional Comparisons
In Telangana: The main lookalike is the Purple-rumped Sunbird (Leptocoma zeylonica). While the male Purple Sunbird is entirely dark, the Purple-rumped male sports a brilliant, non-iridescent lemon-yellow belly that makes identification easy.
Across India: In the southern peninsula, it overlaps with Loten’s Sunbird (Long-billed Sunbird, Cinnyris lotenius). Loten's is larger, has a noticeably longer, more curved beak, and possesses a distinct maroon breast band absent in the Purple Sunbird.
South East Asia: In countries like Thailand or Vietnam, the Purple Sunbird's range ends, yielding to the Crimson Sunbird and the Olive-backed Sunbird (Cinnyris jugularis). The Olive-backed male features a bright yellow belly and an iridescent blue throat, easily separating it from the completely dark breeding male Purple Sunbird.
The Purple Sunbird is a highly successful geographic colonizer. Beyond the limits of Hyderabad and Amrabad, the bird is distributed evenly across Telangana. It is a common sight in the rocky scrub forests of the Kinnerasani Wildlife Sanctuary, the teak forests of Kawal Tiger Reserve, and the agricultural plains of Pakhal and Warangal.
Across India, the Purple Sunbird is nearly ubiquitous. It is found from the desert fringes of Rajasthan and the plains of Punjab to the foothills of the Himalayas (up to 2,400 metres) and all the way south to the tip of Tamil Nadu. It only avoids the dense, hyper-humid rainforest zones of the Western Ghats and the extreme northeast, where other specialized sunbird species dominate.
On a global scale, the Purple Sunbird spans vast stretches of Asia:
West Asia: Found in parts of the Arabian Peninsula, including Oman and the United Arab Emirates, extending into Iran and Pakistan.
South Asia: Found abundantly throughout India, Bangladesh, Nepal, and Sri Lanka.
Southeast Asia: Its easternmost limits push into Myanmar, where its territory begins to transition into the habitats of Southeast Asian endemic sunbirds.
The preferred habitat of the Purple Sunbird includes dry deciduous forests, open thorn scrub, agricultural countrysides, urban parks, and gardens. It has a strong preference for semi-arid environments. This creates interesting ecological overlaps. In places like Amrabad, it lives alongside the Purple-rumped Sunbird. To avoid competing for food, they partition the habitat: the Purple-rumped Sunbird tends to stay closer to riverine patches and wetter valleys, while the Purple Sunbird claims the arid, rocky hill slopes and dry scrub. In Hyderabad's urban spaces, the Purple Sunbird readily occupies drier, degraded land where exotic garden plants bloom, showing a wider tolerance for habitat degradation than its cousins.
The Purple Sunbird behaves like an Old World equivalent of the American Hummingbird. It flies with rapid, jerky wingbeats, hovering momentarily in front of a flower to feed, though it prefers to perch on a twig while probing a blossom. Its diet consists primarily of nectar, but it regularly hunts spiders, caterpillars, and midges, particularly when raising its chicks, who require a high-protein diet.
While the Purple Sunbird is adaptable, human interference is forcing unusual behavioral shifts:
Dietary Shifts to Invasive Species: Due to deforestation and the clearing of native scrub for high-rises around Ameenpur and Kudikunta, native nectar trees like Acacia and Butea have drastically declined. Sunbirds have been forced to rely heavily on invasive plants like Prosopis juliflora and introduced ornamental garden plants.
Aggressive Territorialism: Habitat loss concentrates bird populations into smaller green fragments. In Hyderabad's parks, male sunbirds have become hyper-aggressive, spending valuable energy chasing away rivals, butterflies, and even larger birds from lonely flowering bushes.
Nesting in Plastic and Concrete: Perhaps the most alarming change is their nesting behavior. Traditionally, the female constructs a hanging, pouch-like nest made of cobwebs, lichens, bark bark, and dried leaves. In urban Hyderabad, due to the lack of natural materials, sunbirds now regularly incorporate plastic wrappers, synthetic threads, and human hair into their nests. They also attach these nests to hanging electric wires, balcony rafters, and air conditioning units instead of tree branches, exposing their young to urban heat islands and electrocution risks.
The Courting Virtuoso and the Mirror Mystery
During the breeding season (typically before the monsoons), the male Purple Sunbird exhibits fascinating courtship rituals. He perches near a female, raises his head, spreads his tail, and flutters his wings while continuously flashing his bright yellow and scarlet pectoral tufts. This visual display is accompanied by a surprisingly loud, cheerful song: a rapid cheewit-cheewit-cheewit that echoes across the neighborhood. A quirky, well-documented behavior of this bird in urban areas is its obsession with glass mirrors and reflective car windows. Confusing its own reflection for a rival male intruding on its territory, a male Purple Sunbird will spend hours furiously pecking at a car mirror, fluttering up and down in a tireless, imaginary battle.
The Purple Sunbird represents nature's resilience. As the forests of Amrabad face pressures and the lakes of Hyderabad struggle against urban sprawl, this little bird continues to sing its vibrant song, a reminder of the wild beauty that lives just outside our windows.
