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.

SMITHSONIAN MISCELLANEOUS COLLECTIONS VOLUME 131, NUMBER 9 BREEDING AND OTHER HABITS OF CASQUED HORNBILLS (BYCANISTES SUBCYLINDRICUS) (With 6 Plates) By LAWRENCE KILHAM Bethesda, Md. (Publication 4259) CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN INSTITUTION NOVEMBER 8, 1956 THE LORD BALTIMORE PRESS, INC. BALTIMORE, MD., U. S. A. PREFACE I went to Uganda at the invitation of the East African High Com- mission to carry on virus research as a visiting scientist at the Virus Research Institute, Entebbe, where I worked from August 1954 until mid-May 1955. My ornithological observations were made as an ama- teur in the early mornings and evenings, and on weekends. It had been my hope to study some particular field problem in addition to making a general acquaintance with African bird life. The nature of the prob- lem was determined soon after my arrival. In my bird notes, black- and-white casqued hornbills [Bycanistes suhcylindricits (Sclater)] soon took up more pages than any other species. They came to our garden frequently. In addition, a pair of them roosted and carried on courtship activities in a tree above our house. When I discovered a concentration of hornbill nests in the Mpanga Research Forest, it was apparent that I had an unusual opportunity to study the natural history of casqued hornbills. Present studies did not begin until many females were already walled in. A few pairs of late-nesting hornbills, however, enabled me to witness the beginning stages of nesting ac- tivity. Observations on 16 nesting pairs gave, in the aggregate, a rounded picture of breeding and other habits of these birds. -
PAPUA NEW GUINEA Paradise Untamed
Tropical Birding: Papua New Guinea July-August 2010 A Tropical Birding Set Departure Tour PAPUA NEW GUINEA (with the NEW BRITAIN EXTENSION): Paradise Untamed RIBBON-TAILED ASTRAPIA Kumul Lodge Voted bird of the trip 15 July – 5 August, 2010 Tour Leader: Sam Woods www.tropicalbirding.com [email protected] 1-409-515-0514 1 Tropical Birding: Papua New Guinea July-August 2010 Papua New Guinea is known as the “land of unexpected”, and their national saying is “expect the unexpected”. For good, and bad, we experienced some examples of this during this successful tour on this resource-rich island, and ammased a great trip list of 407 species . Some of what we saw was very much expected: a slew of species from arguably the most spectacular bird family on the planet, the outrageous birds-of-paradise. We picked up 24 species of birds-of-paradise on the tour, with the majority being males, some of which were seen in full, jaw-dropping display mode! The flurry of displaying male Greater Birds-of-paradise during a late afternoon show in the steamy lowland jungle near Kiunga standing out, as did the wonderful performance put on by PNG’s national bird, the Raggiana Bird-of- paradise near the nation’s capital, at Varirata NP. Getting a bunch of BOPs was expected, even in the land of the unexpected. However, on only our third day in the country watching a tree full of BOPs, of NINE different species (and 3 sicklebill species at one time in the same tree ) was very much unexpected even in New Guinea. -
Predictable Evolution Toward Flightlessness in Volant Island Birds
Predictable evolution toward flightlessness in volant island birds Natalie A. Wrighta,b,1, David W. Steadmanc, and Christopher C.

Estes, University of California, Santa Cruz, CA, and approved March 9, 2016 (received for review November 19, 2015) Birds are prolific colonists of islands, where they readily evolve distinct predators (18). Alternatively, flightlessness may represent an ex- forms. Identifying predictable, directional patterns of evolutionary treme state of a continuum of morphological variation that reflects change in island birds, however, has proved challenging. The “island locomotory requirements for survival and reproduction. Across a rule” predicts that island species evolve toward intermediate sizes, but continuum of insularity, from continents to small islands, biotic its general applicability to birds is questionable. However, convergent communities exhibit gradients of species diversity (21) and corre- evolution has clearly occurred in the island bird lineages that have sponding ecological pressures (22). If flightlessness is illustrative of undergone transitions to secondary flightlessness, a process involving island bird evolution in general, reductions in predation pressure drastic reduction of the flight muscles and enlargement of the hin- associated with increased insularity should trigger incremental shifts dlimbs. Here, we investigated whether volant island bird populations in energy allocation from the forelimbs to the hindlimbs.

2009 Trip Report KENYA
KENYA and TANZANIA TRIP REPORT Sept 25-Oct 23, 2009 PART 1 - Classic Kenya text and photos by Adrian Binns Sept 25 / Day 1: Blue Post Thika; Castle Forest We began the morning with an unexpected Little Sparrowhawk followed by a Great Sparrowhawk, both in the skies across the main road from the Blue Post Hotel in Thika. The lush grounds of the Blue Post are bordered by the twin waterfalls of the Chania and Thika, both rivers originating from the nearby Aberdare Mountain Range. It is a good place to get aquatinted with some of the more common birds, especially as most can be seen in close proximity and very well. Eastern Black-headed Oriole, Cinnamon-chested Bee- eater, Little Bee-eater, White-eyed Slaty Flycatcher, Collared Sunbird, Bronzed Mannikin, Speckled Mousebird and Yellow-rumped Tinkerbird were easily found. Looking down along the river course and around the thundering waterfall we found a pair of Giant Kingfishers as well as Great Cormorant, Grey Heron and Common Sandpiper, and two Nile Monitors slipped behind large boulders. A fruiting tree provided a feast for Yellow-rumped Seedeaters, Violet-backed Starlings, Spot-flanked Barbet (right), White-headed Barbet as a Grey-headed Kingfisher, an open woodland bird, made sorties from a nearby perch. www.wildsidenaturetours.com www.eastafricanwildlifesafaris.com © Adrian Binns Page 1 It was a gorgeous afternoon at the Castle Forest Lodge set deep in forested foothills of the southern slope of Mt. Kenya. While having lunch on the verandah, overlooking a fabulous valley below, we had circling Long-crested Eagle (above right), a distant Mountain Buzzard and African Harrier Hawk. -
Life History of the Broad-Billed Motmot, with Notes on the Rufous Motmot
LIFE HISTORY OF THE BROAD-BILLED MOTMOT, WITH NOTES ON THE RUFOUS MOTMOT ALEXAWDERF. SKUTCH N earlier papers (1945, 1947, 1964) 1 gave accounts of the habits of three I species of motmots that inhabit more or less open country, or cool woodland on high mountains. The present paper deals with two species of the wet lowland forest. The nests of these two motmots that we chiefly studied were in sight of each other on the “La Selva” nature preserve, which lies along the left bank of the Rio Puerto Viejo just above its confluence with the Rio Sarapiqui, a tributary of the Rio San Juan in the Caribbean lowlands of northern Costa Rica. They were watched during two visits to this locality, from April to June in 1967 and from March to early June in the following year. The heavy forest of this very rainy region, with its tall, epiphyte-burdened trees, its undergrowth dominated by low palms, and its exceptionally rich avifauna, has been well described by Slud (1960). BROAD-BILLEDMOTMOT (Electron platyrhynchum) One of the smaller members of its family, the Broad-billed Motmot is about 12 inches long. The foreparts of its short body, including the head, neck, and chest, are mainly cinnamon-rufous, with a large black patch on either side, covering the cheeks and auricular region, another black patch in the center of the foreneck, and greenish blue on the chin and upper throat. The posterior parts of the body, including the back and rump, breast and abdomen, are green, more olivaceous above, more bluish below. -

Tanzania 16 - 27 April 2018 Tour Leader Tertius Gous Photographs by Tertius Gous taken on this tour www.birdingafrica.com Day 0: The first day was spent birding and relaxing at our lodge near Kilimanjaro International Airport while we waited for everyone to arrive. The open Acacia savanna surrounding the lodge always provides a very productive start to the tour and notable sightings included Speckled and Blue- naped Mousebird, White-browed Coucal, Mourning Collared Dove, Little and African Palm Swift, European Roller, Grey-headed Kingfisher, African Hoopoe, Red-backed Shrike, Long-tailed Fiscal, Dark-capped Bulbul (the first of many!), Northern and Red-faced Crombec, Willow Warbler, Eastern Olivaceous Warbler, Tawny-flanked Prinia, Buff-bellied Warbler, Garden Warbler, Winding Cisticola, Spotted Flycatcher, Spotted Palm Thrush, Superb and Violet-backed Starling, Scarlet- chested and Variable Sunbird, Red-billed Firefinch, Blue-capped Cordon-bleu, Crimson-rumped Waxbill and Reichenow’s Seedeater, while Yellow-winged Bat showed well at the lodge. As a bonus, our lodge was perfectly situated for spectacular views of Mount Kilimanjaro, Africa's highest mountain and the highest free-standing mountain in the world. Days 1- 2: We spent two full days exploring the grasslands, lakes, woodlands and forests of Arusha National Park. Close to the entrance of the Park we found a breeding colony of Taveta Weavers supported by a few Golden-backed Weavers and an obliging Brown-breasted Barbet. Soon after we entered the Park an open grassy meadow produced good numbers of African Buffalo with numerous Red- billed Oxpeckers in attendance, as well as Bushbuck. Other mammals found in the grasslands and woodlands included Common Zebra, Giraffe, Warthog, Waterbuck, Kirk’s Dik-dik and numerous troops of Olive Baboons, while the forests held Harvey’s Duiker and the diminutive Suni. -

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. -
The Gambia: a Taste of Africa, November 2017
Tropical Birding - Trip Report The Gambia: A Taste of Africa, November 2017 A Tropical Birding “Chilled” SET DEPARTURE tour The Gambia A Taste of Africa Just Six Hours Away From The UK November 2017 TOUR LEADERS: Alan Davies and Iain Campbell Report by Alan Davies Photos by Iain Campbell Egyptian Plover. The main target for most people on the tour www.tropicalbirding.com +1-409-515-9110 [email protected] p.1 Tropical Birding - Trip Report The Gambia: A Taste of Africa, November 2017 Red-throated Bee-eaters We arrived in the capital of The Gambia, Banjul, early evening just as the light was fading. Our flight in from the UK was delayed so no time for any real birding on this first day of our “Chilled Birding Tour”. Our local guide Tijan and our ground crew met us at the airport. We piled into Tijan’s well used minibus as Little Swifts and Yellow-billed Kites flew above us. A short drive took us to our lovely small boutique hotel complete with pool and lovely private gardens, we were going to enjoy staying here. Having settled in we all met up for a pre-dinner drink in the warmth of an African evening. The food was delicious, and we chatted excitedly about the birds that lay ahead on this nine- day trip to The Gambia, the first time in West Africa for all our guests. At first light we were exploring the gardens of the hotel and enjoying the warmth after leaving the chilly UK behind. Both Red-eyed and Laughing Doves were easy to see and a flash of colour announced the arrival of our first Beautiful Sunbird, this tiny gem certainly lived up to its name! A bird flew in landing in a fig tree and again our jaws dropped, a Yellow-crowned Gonolek what a beauty! Shocking red below, black above with a daffodil yellow crown, we were loving Gambian birds already. -
Use of Field Recorded Sounds in the Assessment of Forest Birds in Palawan, Philippines ______Required in the Field [19]

Bernardo Jr. www.apjmr.com College of Arts and Sciences, Western Philippines University, CHED Recognized Journal Aborlan, Palawan, Philippines ASEAN Citation Index [email protected] Date Received: August 3, 2018; Date Revised: February 8, 2019 Abstract -The uses of bioacoustics in biological applications are getting popular in research communities. Among such application is the use of sound recordings in avifaunal researches. This research explored the possibility of using the sound recording in the assessment of forest birds in Palawan by comparing it in widely used Point Count Method (PCM). To compare the two methods, a simultaneous point count and sound recording surveys from February to November 2017 in the forested slopes of Victoria-Anipahan Mountain in Aborlan, Palawan were conducted. The Sound Recording Method (SRM) listed slightly lower species richness than the PCM, but the difference in the mean number of species was not significant (F1,49=1.05, p > 0.05). The SRM was found to be biased towards noisy and loud calling bird species but it failed to detect the silent and rarely calling species. SRM was also equally sensitive as compared to PCM in detecting endemic and high conservation priority species. Because of these, it was recognized that SRM could be used as one of the alternative methods in forest bird assessment particularly if the concern is avifaunal species richness.
