Hornbills of Borneo
The following two species can be easily confused. They can be recognized If you want to support Hornbill Conservation in Sabah, please contact from other hornbill species by the yellow coloration around the head and neck in Marc Ancrenaz at Hutan Kinabatangan Orangutan Conservation Project: the males. The females have black heads and faces and blue throat pouches. [email protected] HORNBILLS OF BORNEO Wrinkled hornbill (Aceros corrugatus): A large, mainly black hornbill whose tail is mostly white with some black at the base. Males have a yellow bill and more prominent reddish casque while females have an all yellow bill and casque. SABAH MALAYSIA The presence of hornbills in the Kinabatangan area is an indication that the surrounding habitat is healthy. Hornbills need forests for nesting and food. Forests need hornbills for dispersal of seeds. And the local people need the forests for wood Wreathed hornbill (Rhyticeros undulatus): A large, primarily black hornbill products, clean water and clean air. They are all connected: whose tail is all white with no black at the base. Both sexes have a pale bill with a small casque and a dark streak/mark on the throat pouch. people, hornbills and forests! Eight different hornbill species occur in Borneo and all are found in Kinabatangan. All are protected from hunting and/or disturbance. By fostering an awareness and concern of their presence in this region, hornbill conservation will be ensured for future generations.

Taxonomy of the Mirafra Assamica Complex
FORKTAIL 13 (1998): 97-107 Taxonomy of the Mirafra assamica complex PER ALSTROM Four taxa are recognised in the Mirafra assamicacomplex: assamica Horsfield, affinis Blyth, microptera Hume, and marionae Baker; subsessorDeignan is considered to be a junior synonym of marionae. These four taxa differ in morphology and especially in vocalizations. Both assamicaand microptera have diagnostic song-flights, while affinis and marionae have similar song-flights. There are also differences in other behavioural aspects and habitat between assamicaand the others. On account of this, it is suggested that Mirafra assamicasensu lato be split into four species:M assamica,M affinis,M micropteraand M marionae.English names proposed are: Bengal Bushlark, ] erdon' s Bushlark, Burmese Bushlark and Indochinese Bushlark, respectively. The Rufous-winged Bushlark Mirafra assamica Horsfield (including the holotype) on my behalf in the Smithsonian is usually divided into five subspecies: assamica Horsfield Institution, Washington, D.C., USA. I have examined c. (1840), affinis Blyth (1845), microptera Hume (1873), 20 specimens of ceylonensis, though I have not compared it subsessor Deignan (1941), and marionae Baker (1915) in detail with affinis, and I have only measured four (Peters 1960, Howard and Moore 1991). One further specimens (of which two were unsexed). For all taxa, taxon, ceylonensis Whistler (1936), is sometimes recognized, measurements of wing length (with the wing flattened and but following Ripley (1946) and Vaurie (1951) most recent stretched; method 3, Svensson 1992), tail length, bill length authors treat it as a junior synonym of affinis. The name (to skull), bill depth (at distal end of nostrils), tarsus length marionae is actually predated by erythrocephala Salvadori and hind-claw length were taken of specimens whose labels and Giglioli (1885), but this does not appear to have been indicated their sex. -
Observations on Rufous-Necked Aceros Nipalensis and Austen's
Observations on Rufous-necked Aceros nipalensis and Austen’s Brown Anorrhinus austeni Hornbills in Arunachal Pradesh: natural history, conservation status, and threats Aparajita Datta Datta, A. 2009. Observations on Rufous-necked Aceros nipalensis and Austen’s Brown Anorrhinus austeni Hornbills in Arunachal Pradesh: natural history, conservation status, and threats. Indian Birds 5 (4): 108–117. Aparajita Datta, Nature Conservation Foundation, 3076/5, 4th Cross, Gokulam Park, Mysore 570002, Karnataka, India. Email: [email protected]. In 1997–1998, Ravi Sankaran had spent three months studying the most interesting, and intriguing, hornbill species found in India, with the smallest global range—the Narcondam Hornbill Aceros narcondami—restricted to a 6 km2 island of the Andaman Islands archipelago. While others before him had spent time on the island and made observations, his were the first systematic and meticulously collected data of a study carried out throughout the breeding season, on a large number of nests. Unfortunately, he never wrote up the work as a publication, but he put his research to good use for conservation action and managed to get the goats that were affecting the regeneration of many hornbill food plants, removed from the island. My paper, in this memorial issue, is about my limited observations on two of the lesser-known, and threatened hornbills of north-eastern India. Abstract Among the five species of hornbills that occur in north-eastern India, the least studied are the endangered Rufous-necked Hornbill Aceros nipalensis, and the Brown Hornbill Anorrhinus austeni1, which has a restricted distribution in India. Based on field surveys conducted in Namdapha National Park, and several forest divisions in eastern Arunachal Pradesh, during 1996–1999 and 2002–2004, I present information on their distribution and relative abundance. -
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). -
Project Update: July 2010 Sixty Percent of Asia's Forests Are Under High Or Moderate Threat
Project Update: July 2010 Sixty percent of Asia’s forests are under high or moderate threat (Bryant et al., 1997). The main threats for forest loss and degradation are logging, habitat conversion, wildfires, fuel wood collection, overgrazing and plantations. The fundamental triggers behind these activities are probably, increasing human populations, roads penetrating deeper and deeper into the forests and weak economies of respective countries. However, the relative impacts of these factors are still unclear and less apparent. Amongst the causes listed above, logging alone affects a large area of forested tracts in Asia. Logging directly results in change in the structure and composition of forests, in modification of microhabitats and it affects wildlife populations differentially. Responses of different taxa and species within taxa vary to differential pressures of logging. Another serious threat to wildlife populations is hunting. Hunting is widespread across various areas of South and South-east Asia (Bennett et al., 1997; Kinnaird and O'Brien, 2007; Milner-Gulland et al., 2003; Robinson and Bennett, 2000). Rural tribal communities hunt for various reasons from meeting dietary needs and protein requirements, to hunting specific species for valuable, culturally significant, or medicinally important body parts. Asian hornbills are a group of large birds, which are restricted to the tropical forests of South and South-east Asia. There are 31 species of hornbills. Hornbills face severe threats from both logging and hunting. Unlike many other hole-nesting birds, hornbills are secondary cavity-nesters, which mean they cannot make their own cavity. They require large cavities on tall emergent large trees especially because the female incarcerates herself in the nest during the breeding season. -
Western India Tour Report 2019
We had great views of the critically endangered Great Indian Bustard in Desert National Park (Frédéric Pelsy). WESTERN INDIA 23 JANUARY – 8 FEBRUARY 2019 LEADER: HANNU JÄNNES Another very successful Birdquest tour to western of India traced an epic route through the states of Punjab, Rajasthan and Gujarat, with a short visit to the state of Maharasthra to conclude. We recorded no fewer than 326 bird species and 20 mammals, and, more importantly, we found almost every bird specialty of the dry western and central regions of the subcontinent including a number of increasingly scarce species with highly restricted ranges. Foremost of these were the impressive Great Indian Bustard (with a world population of less than 100 individuals), the stunningly patterned White-naped Tit, White-browed (or Stoliczka’s) Bush Chat and the Critically Endangered Indian Vulture. Many Indian subcontinent endemics were seen with Rock Bush Quail, Red Spurfowl, Red-naped (or Black) Ibis, Indian Courser, Painted Sandgrouse, the very localized Forest Owlet, Mottled Wood Owl and Indian Eagle-Owl, White-naped Woodpecker, Plum-headed and Malabar Parakeets, Bengal Bush, Rufous-tailed and Sykes’s Larks, Ashy- crowned Sparrow-Lark, the lovely White-bellied Minivet, Marshall’s Iora, Indian Black-lored Tit, Brahminy 1 BirdQuest Tour Report: Western India www.birdquest-tours.com Starling, Rufous-fronted Prinia, Rufous-vented Grass-Babbler, Green Avadavat, Indian Scimitar Babbler, Indian Spotted Creeper, Vigors’s Sunbird, Sind Sparrow and the range restricted western form -

Pied Falconet 4. Ibisbill 2. Greater Adjutant 5. Wedge-tailed Green Pigeon 3. White-winged Duck Honourable mentions: Slender-billed Vulture, Swamp Francolin & Slender-billed Babbler Tour Summary: Our adventure through the north-east Indian subcontinent began in the bustling city of Guwahati, the capital of Assam province in north-east India. We kicked off our birding with a short but extremely productive visit to the sprawling dump at the edge of town. Along the way we stopped for eye-catching, introductory species such as Coppersmith Barbet, Purple Sunbird and Striated Grassbird that showed well in the scopes, before arriving at the dump where large frolicking flocks of the endangered and range-restricted Greater Adjutant greeted us, along with hordes of Black Kites and Eastern Cattle Egrets. Eastern Jungle Crows were also in attendance as were White Indian One-horned Rhinoceros and Citrine Wagtails, Pied and Jungle Mynas and Brown Shrike. A Yellow Bittern that eventually showed very well in a small pond adjacent to the dump was a delightful bonus, while a short stroll deeper into the refuse yielded the last remaining target species in the form of good numbers of Lesser Adjutant. After our intimate experience with the sought- after adjutant storks it was time to continue our journey to the grassy plains, wetlands, forests and woodlands of the fabulous Kaziranga National Park, our destination for the next two nights. -
Bird Observations from Valmiki Tiger Reserve, Bihar Anwaruddin Choudhury
CHOUDHURY: Valmiki Tiger Reserve 57 Bird observations from Valmiki Tiger Reserve, Bihar Anwaruddin Choudhury Choudhury, A. U., 2016. Bird observations from Valmiki Tiger Reserve, Bihar. Indian BIRDS 11 (3): 57–63. Anwaruddin Choudhury, Secretary to the Government of Assam, House No. 7, Islampur Road, Near Gate No. 1 of Nehru Stadium, Guwahati 781007, Assam, India. E-mail: [email protected] Manuscript received on 23 November 2015. Abstract Valmiki Tiger Reserve, in Bihar, is a relatively poorly known bird area. Observations from a recent visit (16 October to 06 November 2015) are documented here. Noteworthy records include some globally threatened, and near-threatened species such as Lesser Adjutant Leptoptilos javanica, Swamp Francolin Francolinus gularis, Oriental Darter Anhinga melanogaster, and River Lapwing Vanellus duvauceli. There were records of White-backed Gyps bengalensis and Slender-billed Vultures G. tenuirostris, and Sarus Crane Grus antigone. Historical records of the Bengal Florican Houbaropsis bengalensis, from the general area, also exist. A large roost of migratory Amur Falcons Falco amurensis was also discovered just outside the reserve. Several species could have been reported as new for Valmiki Tiger Reserve, but lack of published materials has made it difficult to identify these. Altogether 246 species of birds were listed in this work although there could be more than 300 species. Most of the summer visitors, such as cuckoos, and winter visitors, such as ducks, and waders, could not be observed owing to the time of visit. Details of some important observations are presented. Conservation issues are discussed briefly, and recommendations are made for the protection of habitats, and birds.
