The Evolutionary Ecology of Elevational Specialization in Tropical
THE EVOLUTIONARY ECOLOGY OF ELEVATIONAL SPECIALIZATION IN TROPICAL MONTANE BIRDS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Benjamin Gardner Freeman February 2016 © 2016 Benjamin Gardner Freeman THE EVOLUTIONARY ECOLOGY OF ELEVATIONAL SPECIALIZATION IN TROPICAL MONTANE BIRDS Benjamin Gardner Freeman, Ph. D. Cornell University 2016 Tropical mountains are the most biodiverse terrestrial systems on Earth. This “megadiversity” is largely because tropical montane species inhabit narrow elevational distributions—understanding why tropical mountains are so biodiverse thus requires understanding the factors that explain elevational specialization. In my dissertation, I explored the role of two factors previously hypothesized to explain why tropical birds inhabit narrow elevational zones—temperature and interspecific competition. In Chapter 1, I describe resurveys of New Guinean montane bird communities originally surveyed by Jared Diamond in the 1960s, and demonstrate rapid warming-associated upslope shifts in these avifaunas. In Chapter 2, I test the hypothesis that these recent upslope shifts are the result of thermal specialization in New Guinean montane birds. However, I find no evidence that species’ exhibit local adaptation to ambient temperature in their thermal physiology (lower critical temperatures and thermal conductances), suggesting New Guinean montane birds’ elevational limits are minimally influenced by thermal specialization. I then use a comparative approach in Chapter 3 to test whether species exhibit local adaptation to cold high elevation environments in body size, and find little evidence that body size clines are positively linked to elevation in both intraspecific and interspecific analyses. These analyses suggest that temperature may primarily exert an indirect influence on tropical birds’ elevational distributions (e.g., by altering biotic interactions with prey, predators or competitors). -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

The Avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, Including Evidence for Long-Term Population Dynamics in Undisturbed Tropical Forest
Ben Freeman & Alexandra M. Class Freeman 30 Bull. B.O.C. 2014 134(1) The avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, including evidence for long-term population dynamics in undisturbed tropical forest Ben Freeman & Alexandra M. Class Freeman Received 27 July 2013 Summary.—We conducted ornithological feld work on Mt. Karimui and in the surrounding lowlands in 2011–12, a site frst surveyed for birds by J. Diamond in 1965. We report range extensions, elevational records and notes on poorly known species observed during our work. We also present a list with elevational distributions for the 271 species recorded in the Karimui region. Finally, we detail possible changes in species abundance and distribution that have occurred between Diamond’s feld work and our own. Most prominently, we suggest that Bicolored Mouse-warbler Crateroscelis nigrorufa might recently have colonised Mt. Karimui’s north-western ridge, a rare example of distributional change in an avian population inhabiting intact tropical forests. The island of New Guinea harbours a diverse, largely endemic avifauna (Beehler et al. 1986). However, ornithological studies are hampered by difculties of access, safety and cost. Consequently, many of its endemic birds remain poorly known, and feld workers continue to describe new taxa (Prat 2000, Beehler et al. 2007), report large range extensions (Freeman et al. 2013) and elucidate natural history (Dumbacher et al. 1992). Of necessity, avifaunal studies are usually based on short-term feld work. As a result, population dynamics are poorly known and limited to comparisons of diferent surveys or diferences noticeable over short timescales (Diamond 1971, Mack & Wright 1996). -

Upon arrival, we transferred to our comfortable hotel on the outskirts of Lae city. A walk around the expansive grounds turned up some 23 species to get our lists well underway, including Orange-bellied and Pink-spotted Fruit Dove (the latter of the distinct and range-restricted plumbeicollis race), Torresian Imperial Pigeon, Eclectus Parrot, and Yellow-faced Myna, not to mention perhaps 1,000 Spectacled Flying Foxes creating quite the sight and sound! Early the next morning we were back at Nadzab airport, where a quick scan of the airfield produced some Horsfield’s Bush Larks and also excellent looks at a male Papuan Harrier that did a close flyby being bombarded by numerous Masked Lapwings! We were soon boarding our charter flight Pink-spotted Fruit Doves by Holger Teichmann over the rugged Huon mountains, although we quickly entered dense clouds and could see nothing of these impressive mountains. After some half an hour of flying through thick cloud on the plane’s GPS track, we suddenly descended and made an uphill landing at Kabwum airstrip! Our land cruiser was there, waiting for us, and after loading bags and ourselves onboard we made the bumpy drive up many switchbacks to reach the high ridge above Kabwum. -
Nest, Egg, Incubation Behaviour and Vocalisations of the New Guinea Endemic Black Pitohui Melanorectes Nigrescens

Email: [email protected] Abstract. The Black Pitohui Melanorectes nigrescens (Pachycephalidae) is endemic to mid-mountain forests in mainland New Guinea. Spectrograms of three different songs recorded in the Yopno Urawa Som Conservation Area (YUS CA), Huon Peninsula, Papua New Guinea, are presented. We describe the elevation and nest-site, height above the ground, structure and materials of a nest with an egg, discovered in the YUS CA. The colour and dimensions of the egg are documented. We present photographs of the nest-site, nest, and egg, and compare these with previously described eggs and a nest. We observed only the female Black Pitohui incubating the single-egg clutch. We compare the meagre information on pitohui breeding biology with that of Australian whistlers and shrike-thrushes. Introduction (Bell 1983). In lowland rainforest sites, flock composition was more influenced by the presence of Papuan Babblers Garritornis isidori (Pomatostomidae) than by that of The genus Melanorectes was resurrected by Dumbacher pitohuis, indicating that pitohui toxicity does not drive flock (2014) for the Black Pitohui, previously named Pitohui organisation (Goodale et al. 2012). -

David Bishop David Bishop Bird Tours 2014 David Bishop Bird Tours Papua New Guinea and NE Queensland March 20 – April 6, 2014 Leader: David Bishop This bespoke tour was specially designed to seek out some very distinctive, elusive families and near-families in addition to as many as possible of the distinctive genera. In this and just about everything else I think it fair to say we were enormously successful. This was in no small part due to Tim’s skill in the field and general diligence plus some fine help in from the likes of Leonard, Daniel, Sam and Max. Undoubtedly this was one of the most thoroughly enjoyable and stimulating tours I have ever operated. We both learnt a great deal, for me not least that birding in PNG during late March and early April makes a very pleasant and productive change from the more traditional months. Needless to say we shared a great deal of fun in addition to enjoying some truly spectacular birds, landscape as well some fine cultural experiences. Despite PNG’s sometimes, insalubrious reputation, the people are undoubtedly among the most friendly and fascinating peoples on our planet. Just a handful of this tour’s highlights included: An enormous adult male Southern Cassowary permitted a very close encounter for 30 minutes at Cassowary House – I do believe New Guineans are correct in NOT classifying this beast as a bird! One of the very best day’s birding I can ever recall in Varirata National Park. -
Papua New Guinea Highlands Extension
PAPUA NEW GUINEA CRUISE HIGHLANDS EXTENSION OCTOBER 5–11, 2019 Ribbon-tailed Astrapia© David Wolf LEADERS: DAVID & MIMI WOLF With Local Leaders Wilson and Joseph LIST COMPILED BY: DAVID E. WOLF VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM No group of birds says “New Guinea” more than the fabulous Birds-of-Paradise, noted for their brilliant plumage and elaborate ornamentation, and they were the focus of this Extension. Very few are found in the lowlands, so to see a variety of them we headed for the Central Highlands. We couldn’t have been more successful in our quest! After a difficult check-in at the Rabaul Airport, with no electricity and everything done by hand, we finally took off for Port Moresby, only to arrive and find that our flight to Mt. Hagen had been canceled. We became “the disrupted,” but got a very good meal out of it that evening! Early the next morning we flew to Mt. Hagen in beautiful weather, coming in right over the incredibly rugged and heavily forested spine of the mountains. By lunchtime we had arrived at rustic Kumul Lodge in the upper montane forest, where an amazing sight greeted us as we stepped onto the back balcony overlooking their bird- feeding tables. There were birds simply everywhere, the gorgeous Ribbon-tailed Astrapias the standout. Never did we imagine that Crested Berrypecker © David Wolf we would see our first spectacular birds-of- paradise right in front of us at close range! Male, female, juvenile—all were there as we pulled out cameras and fired away. -
New Guinea & Australia 2019
Field Guides Tour Report New Guinea & Australia 2019 Oct 8, 2019 to Oct 26, 2019 Jay VanderGaast For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Nobody wants to miss seeing cassowary, but it was looking like we might until this one wandered onto the beach at Etty Bay and proceeded to forage unconcernedly down the whole length of the beach, accompanied by an entourage of admirers, our group included. What an amazing encounter! Photo by guide Jay VanderGaast. Australia and Papua New Guinea are a natural fit to pair up on a tour such as this. Aside from being close together, they share a similar avifauna, with a lot of families, and a fair number of species, occurring in both countries. On the other hand, they also each have their own distinct flavor, and plenty of endemics, making them both excellent destinations on their own. Quite obviously, no single tour to either country can even come close to cleaning up on the birds, and this tour certainly makes no attempt to do that. It is more a tour of highlights, and one thing is for certain, there were plenty of those everywhere we went! Things started off on a high note on our first outing in the Cairns region, where in addition to a nice list of expected species, we tallied a trio of Lovely Fairywrens at Cattana Wetlands and a gorgeous Little Kingfisher at Yorkey's Knob, and it just kept on rolling from there. A few days later, by the time we moved on to PNG, we'd enjoyed a close encounter with an imposing Southern Cassowary at Etty Bay, admired the brilliant colors of Wompoo and Rose-crowned Fruit-Doves, had an impromptu photos session with a stunning Spotted Harrier, and been introduced to an assortment of range-restricted specialties of the Atherton Tablelands, from quirky Chowchillas kicking leaves around in the understory, to the display of a shimmering male Victoria's Riflebird, to the construction prowess of a Golden Bowerbird. -

Rev. Henry Ward Beecher The news is spreading among bird-watchers that the Stitchbird or hihi (Notiomystis cincta) might mid 19th Century not be a honeyeater. It looks and behaves quite like a honeyeater (Meliphagidae), and has long been assigned to that family along with the Tui and New Zealand Bellbird. However, Stitchbirds also have some features atypical of honeyeaters, such as long bristles at the gape, erectile ear- Contents tufts and the habit of hole-nesting. In 2001, Amy Driskell, a student at the University of Chicago, completed a PhD thesis that Snares Island Snipe Transfer 3 used DNA sequences from one nuclear and three mitochondrial genes to examine phylogenetic relationships among about one third of the world’s 180 species of honeyeaters.

The White-browed Fantail Flycatcher (Rhipidura aureola) is a widely distributed species Received: 12 November 2018; in tropical regions of the Indian subcontinent and in Southeast Asia. We determined the breeding accepted 7 January 2019 biology and nest site characteristics of R. aureola in Sri Lanka during 2012 to 2017. All the nests observed were small cup-shaped and without a ‘tail’ extending below the nest base. Both male and Keywords: female R. aureola built their nests within 9–13 days with an average mean external diameter, mean White-browed Fantail internal diameter, and mean depth of, respectively, 6.4 ± 0.32, 5.6 ± 0.22, and 2.9 ± 0.21 cm. The Flycatcher; nest; ecology; R. aureola we found used various habitats such as home gardens, forest boundaries, sanctuaries, Sri Lanka man-made tanks/water bodies, stream banks, tea plantations and road edges to build their nests. We did not find any change in clutch size (2–3 eggs) with different elevation gradients. The eggs were oval-shaped with the ground colour of pale warm yellow-brown to pink and lots of spots or blotches in dark gray-brown. -
The Dark Side of Birds: Melanism—Facts and Fiction
Hein van Grouw 12 Bull. B.O.C. 2017 137(1) The dark side of birds: melanism—facts and fiction by Hein van Grouw Received 18 August 2016; revised 20 January 2017; published 13 March 2017 Summary.—Melanism is generally defined as an increase of dark pigment in the plumage, resulting in a blackish appearance. Furthermore, melanism is often associated with mutations of one gene that encodes the melanocortin 1 receptor (MC1R), a protein involved in regulating melanin pigmentation. However, there is often no increase of pigment and melanism does not necessarily involve dark pigment alone. Also, many different mutations in many different genes promote melanism, which may explain why it is the commonest colour morph in birds. In the past, melanistic birds were sometimes mistakenly named as new species. Ironically, it now appears that melanistic birds do indeed differ from their normal- coloured conspecifics in more than just colour. ‘Every morphism thus has implications in the field of genetics, ecology, selection theory, field natural history, and taxonomy.’ (J. Huxley, 1955) Melanism, from the Greek melanos (= dark- coloured), is generally defined as an increased amount of dark pigmentation (melanin). However, in this paper it will be demonstrated that an aberrant dark plumage is not necessarily the result of increased amounts of pigment, and that melanism can result in a paler plumage than normal. Colour aberrations, especially melanism, have always confused ornithologists. In the past, when nothing was known concerning plumage pigmentation and mutations, aberrant-coloured birds were often viewed as being new taxa, and were even described scientifically. Perhaps the oldest and best-known example of a melanistic aberration named as a new species is Mountain Partridge Perdix montana (Brisson 1760).
