Brown Hornbill

Observing the Brown Hornbill (Anorrhinus tickelli) in Arunachal Pradesh

The forests of Arunachal Pradesh are home to a remarkable array of avian life, among them the Brown Hornbill (Anorrhinus tickelli). This medium-sized hornbill is a resident breeder within the Indo-Malayan region, predominantly found in evergreen broadleaf forests. Its presence is often indicated by its distinctive calls and the visual spectacle of its flight as it moves between tall trees, typically in small foraging groups. Unlike some of its more vibrantly coloured hornbill relatives, the Brown Hornbill possesses a more subdued, yet equally impressive, plumage that allows it to blend effectively into its dense forest environment.

History & Context

Hornbills hold a significant ecological role as 'farmers of the forest' due to their crucial part in seed dispersal. Their diets, rich in fruits, enable them to distribute seeds over wide areas, aiding in forest regeneration. The Brown Hornbill, in particular, contributes to the health and biodiversity of the sub-Himalayan and Southeast Asian ecosystems where it resides. Ornithological records indicate its historic presence across parts of Northeast India, particularly in Arunachal Pradesh, and eastward into Myanmar and neighbouring regions. The species was first described by Colonel Samuel Tickell, an Irish ornithologist and artist, in the mid-19th century, contributing to its nomenclature Anorrhinus tickelli. Its restricted range and specific habitat requirements underscore the importance of forest conservation efforts in Arunachal Pradesh to protect this species and its ecological services.

What Makes It Distinctive

Distinguishing features of the Brown Hornbill include its uniform dark brown plumage, often with a paler, sometimes rufous, belly in males. Females tend to be darker overall. Both sexes possess a prominent, elongated, dull yellowish or pale horn-coloured bill, lacking a large casque, which sets it apart from other hornbill species like the Rufous-necked or Great Hornbills also found in the region. Their facial skin around the eyes is typically bare and blue-greyish in males, while females exhibit a more reddish or purplish bare skin, which can be a key identification mark. They are also known for their social behaviour, often observed in groups of up to 15-20 individuals, moving through the canopy together, a behaviour less common in some of the larger, more solitary hornbill species. Their flight is characterised by heavy wingbeats followed by glides, a typical hornbill locomotion, but performed with a notable agility within the dense canopy.

Best Time to Visit

Birdwatching for the Brown Hornbill is generally productive from October to April. During these months, the weather in Arunachal Pradesh is typically drier and cooler, making forest exploration more comfortable. This period also coincides with the nesting season for some hornbill species, though Brown Hornbills generally breed between March and May. The fruiting season for many forest trees, which is when hornbills are most active in foraging, also peaks in late winter to early spring. The monsoon months (May to September) bring heavy rainfall, which can make forest trails inaccessible and reduce visibility for birdwatching.

How to Reach

Access to potential Brown Hornbill habitats in Arunachal Pradesh involves reaching one of the main entry points into the state.

Nearest Airport: Lilabari Airport (IXI) in North Lakhimpur, Assam, is often the closest commercial airport, approximately 50-60 km from Itanagar. Another option is Dibrugarh Airport (DIB) in Assam, roughly 150 km from Pasighat. From either airport, taxis or shared vehicles are available to various towns within Arunachal Pradesh.
Nearest Railhead: Harmuti railway station in Assam is the nearest broad-gauge railhead for Itanagar, about 35 km away. Naharlagun railway station, 15 km from Itanagar, provides direct rail connectivity. From these stations, taxis can be hired.
Road Route: From Guwahati, Assam, a major hub, the journey to Itanagar covers approximately 350-400 km and can take 8-10 hours by road, depending on traffic and road conditions. Services like buses (government and private) and shared taxis operate regularly to Itanagar and other towns. For deep forest areas, local transport or hiring a dedicated 4x4 vehicle is often necessary.

Permits & Entry

For Indian citizens who are not residents of Arunachal Pradesh, an Inner Line Permit (ILP) is mandatory to enter the state. This can be obtained online through the Arunachal Pradesh government portal or on arrival at designated entry points. Foreign nationals require a Protected Area Permit (PAP). This permit can be obtained through tour operators registered with the Arunachal Pradesh government. It's advisable to apply for permits well in advance of travel. Confirm current fees and application procedures with official sources before planning your trip as regulations can change.

Traveller Tips

Connectivity: Mobile network coverage can be patchy outside major towns; BSNL typically has wider reach in remote areas. Consider carrying a local SIM card.
ATMs: ATMs are available in larger towns like Itanagar and Seppa, but scarce in smaller, remote areas. Carry sufficient cash for expenses.
Dress Code: Lightweight, neutral-coloured clothing is best for jungle treks. Carry waterproof gear and warm layers for evenings and higher altitudes, even outside of winter.
Footwear: Sturdy, waterproof trekking shoes with good grip are essential for navigating forest trails.
Accommodation: Options range from basic guesthouses to homestays in villages near forest areas. Book in advance, especially during peak season.
Ethical Photography: Always maintain a respectful distance from wildlife. Avoid using flash photography, which can disturb birds.
Guides: Hiring local birdwatching guides is highly recommended for locating specific species like the Brown Hornbill and understanding local ecology. They also contribute to the local economy.
Health: Carry basic first-aid supplies, insect repellent, and any personal medications. Consult a doctor about necessary vaccinations before travel.

Living Roots Expert Notes

Our expeditions to Arunachal often focus on the incredible biodiversity, and the various hornbill species are always a highlight. While the Great Hornbill often steals the show with its majestic size, the Brown Hornbill offers a different, more elusive thrill. They are typically seen in smaller groups, moving with remarkable stealth through the high canopy, often requiring patience and keen eyesight. We time our visits to areas like Pakke in winter, not just for the clearer weather, but because the fruiting cycles often bring these amazing birds lower in the canopy as they forage, making for better viewing opportunities.

Guests are always surprised by the sheer number of hornbill calls that punctuate the forest air, and distinguishing between them becomes a fun challenge. It's crucial for visitors to understand that these birds are sensitive to disturbance. We emphasize silent observation and avoiding any behaviour that might alter their natural activities. A good pair of binoculars and a camera with a decent zoom are indispensable, but more importantly, a respect for their often-fragile habitat.

For foreign nationals, the PAP process requires early planning, as it can sometimes take a few weeks to secure. Having a reliable local operator like Living Roots Expeditions significantly streamlines this, ensuring all permit requirements are met well in advance. We also work closely with local communities and guides, providing opportunities for ethical encounters that benefit the region while safeguarding its natural heritage.
