Habitat and Distribution of the Nilgiri Wood Pigeon: Exploring Its Range in the Western Ghats
The Nilgiri Wood Pigeon (Columba elphinstonii) is primarily found in the moist deciduous forests and sholas of the Western Ghats in southwestern India.
Here’s a detailed overview of its habitat and distribution:
Geographic Range
The Nilgiri Wood Pigeon’s territory spans from Maharashtra to Kerala in Southwestern India. It is extensively distributed across various regions, including the Nilgiris, Anamalai Hills, Palni Hills, Mahabaleshwar, and Agasthyamalai.
Their range extends from as far north as Mahabaleshwar to as far south as Agasthyamalai.
Altitude Preference
Nilgiri Wood Pigeons favor locations with higher altitudes, typically ranging from 600 to 2000 meters above sea level. They are commonly found in mountainous terrain within the Western Ghats.
Habitats
Nilgiri Wood Pigeons inhabit dense, moist deciduous forests and shola forests. These habitats provide ideal nesting sites and abundant food resources for the pigeons.
They prefer areas with dense undergrowth, which offers protection and suitable conditions for nesting.
Dietary Preferences
Their diet primarily consists of fruits and seeds found within their natural habitat. They have a special affinity for fruit trees such as Ficus drupacea and wild nutmeg tree (Myristica dactyloides), which form essential parts of their diet.
Avoidance of Disturbed Habitats
Nilgiri Wood Pigeons tend to avoid heavily disturbed habitats or areas with high levels of human intervention. They prefer undisturbed forested areas where they can find suitable nesting sites and ample food resources.
Physical Characteristics of the Nilgiri Wood Pigeon: A Fascinating Dive Into Nature’s Artistry
The Nilgiri Wood Pigeon (Columba elphinstonii) has several distinctive physical characteristics that distinguish it from other pigeon species.
Here’s a detailed overview of its physical attributes:
Size
Nilgiri Wood Pigeons are relatively large birds compared to typical city pigeons. They measure around 40-43 centimeters (16-17 inches) in length, with a wingspan of approximately 22 centimeters (8.7 inches). On average, they weigh around 260 grams.
Plumage
The plumage of Nilgiri Wood Pigeons is predominantly grey, with a maroon patch on the chest area. Their upperparts exhibit an iridescent sheen that ranges from green to purple depending on lighting conditions. This iridescent quality adds to their visual appeal.
Head and Neck
The head of the Nilgiri Wood Pigeon is slate-grey in coloration, with a distinctive white patch around the eyes resembling spectacles. This feature gives them a unique and charming appearance. They have a relatively short neck compared to other pigeon species.
Wings and Tail
Nilgiri Wood Pigeons have broad wings adapted for maneuvering through dense forest habitats. The tail feathers are long and feature an intricate pattern of black-and-white spots, adding to their aesthetic appeal.
Sexual Dimorphism
There is slight sexual dimorphism in Nilgiri Wood Pigeons. Males typically have a more prominent maroon patch on their chest compared to females. However, males and females share similar physical characteristics overall.
Vocalizations
Nilgiri Wood Pigeons have a distinctive cooing call that is soft and melodic. Their vocalizations are often heard during dawn and dusk, serving various purposes such as communication between individuals and attracting mates during the breeding season.
Behavior of the Nilgiri Wood Pigeon: Feeding and Breeding Habits Unveiled
The behavior of the Nilgiri Wood Pigeon (Columba elphinstonii) reflects its adaptation to the forested habitats of the Western Ghats.
Here are some key aspects of its behavior:
Feeding Behavior
Nilgiri Wood Pigeons primarily feed on fruits and seeds found in their natural habitat. Their varied diet includes figs, berries, and occasionally insects for protein.
These pigeons are crepuscular feeders most active during twilight, particularly at dawn and dusk.
Breeding Behavior
Nilgiri Wood Pigeons are monogamous birds, forming long-term pair bonds. Breeding season typically occurs from March to June. During this time, nesting activities commence, with females laying one egg per clutch in nests constructed from twigs and leaves high up in trees.
Both parents are responsible for incubating the eggs, which lasts approximately 14 days.
Parental Care
After hatching, the chicks are altricial, meaning they are born without feathers and depend on parental care for survival.
Both male and female pigeons care for the young, providing them food and protection in the nest. The chicks remain in the nest for about three weeks before fledging and becoming independent.
Vocalizations
Nilgiri Wood Pigeons have distinctive vocalizations, consisting of soft, deep cooing calls often repeated in sequences. These calls, characterized by a low “hoo” followed by quick “coos,” are primarily heard during dawn and dusk.
Vocalizations serve various purposes, including communication between individuals and attracting mates during breeding.
Territorial Behavior
Like many bird species, Nilgiri Wood Pigeons exhibit territorial behavior, particularly during the breeding season. They may defend their nesting sites and foraging areas from intruders, using vocalizations and physical displays to establish dominance and deter rivals.
Habitat Preference
These pigeons prefer dense, moist deciduous forests and sholas in Western Ghats. They tend to avoid heavily disturbed habitats or areas with high levels of human activity.
Conservation Status of the Nilgiri Wood Pigeon
The Nilgiri Wood Pigeon (Columba elphinstonii) is classified as “Vulnerable” by the International Union for Conservation of Nature (IUCN).
Here’s an overview of its conservation status and the threats it faces:
Threats
The primary threat to the Nilgiri Wood Pigeon is habitat loss and fragmentation due to deforestation. The conversion of forests for agricultural purposes, timber extraction, and human settlement destroys their natural habitat.
This habitat loss reduces the availability of suitable nesting sites and food resources for the pigeons.
Hunting and Poaching
Despite legal protections against hunting in many areas, Nilgiri Wood Pigeons are still at risk from illegal poaching. Hunting for food and sport poses a significant threat to their population, particularly in regions where enforcement of conservation laws is inadequate.
Population Decline
The combination of habitat loss and hunting has led to a decline in the population of Nilgiri Wood Pigeons. The species is experiencing a rapid decrease in numbers, raising concerns among conservationists about its long-term survival.
Conservation Efforts
Several conservation efforts are underway to protect the Nilgiri Wood Pigeon and its habitat. These efforts include establishing protected areas within its range, where the pigeons are shielded from threats such as hunting and habitat destruction.
Legal protections against hunting have been implemented in India and Sri Lanka to safeguard the species.
Reforestation Projects
Some organizations are actively involved in reforestation projects to restore the habitats of Nilgiri Wood Pigeons. These initiatives aim to recreate suitable nesting sites and increase the availability of food resources within their range.
Research and Monitoring
Further research into the ecology and behavior of Nilgiri Wood Pigeons is essential for developing effective conservation strategies.
Monitoring population trends and habitat conditions is crucial for assessing conservation efforts’ effectiveness and identifying areas for improvement.
Conclusion
The Nilgiri Wood Pigeon, endemic to the high-altitude forests of Southern India, faces endangerment primarily due to habitat loss from deforestation.
Conservation efforts are imperative as these birds play a vital role in seed dispersal, which is crucial for maintaining biodiversity. Their decline underscores the urgent need for collective action in wildlife conservation.
Protecting the Nilgiri Wood Pigeon isn’t just about preserving a single species; it’s about safeguarding an entire ecosystem that relies on them for balance and harmony.
Understanding their significance highlights the interconnectedness of species and ecosystems, emphasizing our responsibility to preserve our planet’s rich diversity.
It calls for environmental stewardship, uniting ecological organizations and individuals to ensure a sustainable future.
