Great Hornbill Buceros Bicornis, Wreathed Hornbill Aceros Undulatus and Oriental Pied Hornbill Anthracoceros Albirostris
Bird Conservation International (2004) 14:S39–S52. BirdLife International 2004 doi:10.1017/S0959270905000213 Printed in the United Kingdom Nest-site selection and nesting success of three hornbill species in Arunachal Pradesh, north-east India: Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthracoceros albirostris APARAJITA DATTA and G. S. RAWAT Summary Nest-site selection by the sympatric Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthracoceros albirostris was investigated in a lowland tropical forest in Arunachal Pradesh, north-east India during 1997–2000. Infor- mation on two nests of Rufous-necked Hornbill Aceros nipalensis in higher-elevation forests is also presented. All species nested in live trees of three tree genera, 83% (n = 36) in Tetrameles nudiflora, an emergent deciduous softwood, relatively common in lowland foothill forests. No difference was recorded in nest-tree species or nesting habitats of sympatric hornbills, but there were a few differences in structural characteristics of nest- trees. Cavity size was the main variable separating the three species. Great Hornbills used larger cavities while Oriental Pied Hornbills used smaller cavities closer to riverine areas. Nesting was attempted at 64% of known sites and successful fledging of chicks was 80% overall (n = 72 nests, pooled over 4 years). Nest-trees in disturbed habitats near human habitation were used but were often abandoned or unsuccessful and 50% of all nest-trees were inactive by the end of the study. Potential large nest-trees had a density of 5.9/ha, that of the two most used species was 1.3/ha, and minimum nest densities of all three species was about 1 pair/km2. -
Correlates of Hornbill Distribution and Abundance in Rainforest Fragments in the Southern Western Ghats, India
Bird Conservation International (2003) 13:199–212. BirdLife International 2003 DOI: 10.1017/S0959270903003162 Printed in the United Kingdom Correlates of hornbill distribution and abundance in rainforest fragments in the southern Western Ghats, India T. R. SHANKAR RAMAN and DIVYA MUDAPPA Summary The distribution and abundance patterns of Malabar Grey Hornbill Ocyceros griseus and Great Hornbill Buceros bicornis were studied in one undisturbed and one heavily altered rainforest landscape in the southern Western Ghats, India. The Agasthyamalai hills (Kalakad-Mundanthurai Tiger Reserve, KMTR) contained over 400 km2 of continuous rainforest, whereas the Anamalai hills (now Indira Gandhi Wildlife Sanctuary, IGWS) contained fragments of rainforest in a matrix of tea and coffee plantations. A comparison of point-count and line transect census techniques for Malabar Grey Hornbill at one site indicated much higher density estimates in point-counts (118.4/km2) than in line transects (51.5/km2), probably due to cumulative count over time in the former technique. Although line transects appeared more suitable for long-term monitoring of hornbill populations, point-counts may be useful for large-scale surveys, especially where forests are fragmented and terrain is unsuitable for line transects. A standard fixed radius point-count method was used to sample different altitude zones (600–1,500 m) in the undisturbed site (342 point-counts) and fragments ranging in size from 0.5 to 2,500 ha in the Anamalais (389 point-counts). In the fragmented landscape, Malabar Grey Hornbill was found in higher altitudes than in KMTR, extending to nearly all the disturbed fragments at mid-elevations (1,000–1,200 m). -
India: Kaziranga National Park Extension
INDIA: KAZIRANGA NATIONAL PARK EXTENSION FEBRUARY 22–27, 2019 The true star of this extension was the Indian One-horned Rhinoceros (Photo M. Valkenburg) LEADER: MACHIEL VALKENBURG LIST COMPILED BY: MACHIEL VALKENBURG VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM INDIA: KAZIRANGA NATIONAL PARK EXTENSION February 22–27, 2019 By Machiel Valkenburg This wonderful Kaziranga extension was part of our amazing Maharajas’ Express train trip, starting in Mumbai and finishing in Delhi. We flew from Delhi to Guwahati, located in the far northeast of India. A long drive later through the hectic traffic of this enjoyable country, we arrived at our lodge in the evening. (Photo by tour participant Robert Warren) We enjoyed three full days of the wildlife and avifauna spectacles of the famous Kaziranga National Park. This park is one of the last easily accessible places to find the endangered Indian One-horned Rhinoceros together with a healthy population of Asian Elephant and Asiatic Wild Buffalo. We saw plenty individuals of all species; the rhino especially made an impression on all of us. It is such an impressive piece of evolution, a serious armored “tank”! On two mornings we loved the elephant rides provided by the park; on the back of these attractive animals we came very close to the rhinos. The fertile flood plains of the park consist of alluvial silts, exposed sandbars, and riverine flood-formed lakes called Beels. This open habitat is not only good for mammals but definitely a true gem for some great birds. Interesting but common birds included Bar-headed Goose, Red Junglefowl, Woolly-necked Stork, and Lesser Adjutant, while the endangered Greater Adjutant and Black-necked Stork were good hits in the stork section. -

Consequences of Female Nest Confinement in Yellow Billed Hornbills
Conflict & Communication: Consequences Of Female Nest Confinement In Yellow Billed Hornbills Michael Joseph Finnie This dissertation is submitted for the degree of Doctor of Philosophy Clare College September 2012 Michael Joseph Finnie i Preface This dissertation is my own work and contains nothing which is the outcome of work done in collaboration with others, except as specified in the text and acknowledgements. The total length of the text does not exceed 60,000 words, including the bibliography and appendices. No part of this dissertation has been submitted to any other university in application for a higher degree. ii Conflict & Communication: Consequences Of Female Nest Confinement In Yellow-Billed Hornbills Summary The most striking feature of hornbills (Bucerotiformes) is their unusual nesting behaviour. Before laying, a female hornbill enters the nest in a tree cavity. Uniquely among birds, she then seals the nest entrance using her faeces and locally available materials, leaving a narrow gap only 1 cm wide. Through this tiny slit, the female is totally dependent on her mate for between 40 days in the smallest hornbills and up to 130 days in the largest. Once walled in the nest, the female will lay her eggs and shed all of her wing and tail feathers. The male then becomes completely responsible for provisioning his mate and a few weeks later, the chicks. When her feathers have regrown, the female breaks out of the nest, often before the chicks are fully grown. The chicks then reseal the entrance until they too are ready to fledge. This thesis describes attempts to better understand the nesting behaviour of hornbills. -

NORTHERN INDIA: TIGERS, BIRDS AND THE HIMALAYAS TRIP REPORT OCTOBER 2017 By Andy Walker A gorgeous Indian endemic, the Painted Spurfowl, was seen well during the tour. www.birdingecotours.com [email protected] 2 | T R I P R E P O R T India: Tigers, Birds and the Himalayas 2017 This was a customized version of our usual northern India tour, scheduled for January. This tour for Charley and Paul commenced on the 16th of October 2017 at Ranthambhore and concluded in New Delhi on the 30th October 2017. Prior to the tour Charley and Paul took a pre-tour exploring New Delhi and Jaipur and had a one-day extension in New Delhi for some birding there. The tour visited the world-famous Ranthambhore, Keoladeo Ghana (formerly known as Bharatpur Bird Sanctuary), Corbett, and Sultanpur National Parks and spent time in the breathtaking scenery of the Himalayan foothills at Pangot and Sattal. A visit to this part of India would not be complete without taking in the majestic UNESCO World Heritage Sites of Fatehpur Sikri and the Taj Mahal, and so we visited these also. India is well known for its amazing food, and we sampled a great deal of interesting and tasty local dishes throughout the tour. The above combined makes for a perfect Indian birding tour. The tour connected with many exciting birds, such as Indian Skimmer, Indian Courser, Kalij, Koklass, and Cheer Pheasants, Painted Spurfowl, Indian Spotted Eagle, Bearded (Lammergeier), Red-headed, Indian, and Himalayan Vultures, Collared Falconet, Sarus Crane, Black-necked Stork, Small Pratincole, Painted Sandgrouse, Brown Fish Owl, Oriental Scops Owl, Black-bellied and River Terns, Blue-bearded Bee-eater, Great Hornbill, Spotted Forktail, Grey-winged Blackbird, Long-billed and Scaly Thrushes, Himalayan and Siberian Rubythroats, Ultramarine Flycatcher, Striated and Rufous- chinned Laughingthrushes, Grey-crowned Prinia, White-browed Bush Chat, and over 1,600 Red-headed Buntings. -

The Status and Conservation of Hornbills in Cambodia
Bird Conservation International (2004) 14:S5–S11. BirdLife International 2004 doi:10.1017/S0959270905000183 Printed in the United Kingdom The status and conservation of hornbills in Cambodia TAN SETHA Summary Internal security problems from the 1960s up until 1998 prevented any fieldwork in Cambodia. Since then, the situation has improved greatly and the Royal Government of Cambodia, in collaboration with international conservation NGOs, has been conducting general biological surveys across the country. Survey reports were used to investigate current occurrence of hornbills. Historically, three hornbill species — Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthraco- ceros albirostris — were known from Cambodia. Recent surveys show that populations of Great and Wreathed Hornbills have declined significantly since the 1960s, while Oriental Pied is still common. A fourth hornbill species, Brown Hornbill Anorrhinus tickelli, was reported in 1998 in Kirirom National Park spanning the border of Koh Kong and Kompong Speu provinces in south-west Cambodia. Conservation priorities and priorities for future surveys are being developed. Introduction Until recently, only three hornbill species were known to occur in Cambodia: Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus, and Oriental Pied Hornbill Anthracoceros albirostris (Thomas 1964). Two recent records have added Brown Hornbill Anorrhinus tickelli (ssp. austeni). Chak (1998) erroneously stated that eight species had been recorded. It is very unlikely that more than four hornbill species occur in the country. Internal security problems from the 1960s up until 1998 prevented any fieldwork in the country. However, since then the situation has improved greatly and the Royal Government of Cambodia, in collaboration with international conservation NGOs, has been conducting biological surveys across the country. -
