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.

Management and Breeding of Birds of Paradise (Family Paradisaeidae) at the Al Wabra Wildlife Preservation
Management and breeding of Birds of Paradise (family Paradisaeidae) at the Al Wabra Wildlife Preservation. By Richard Switzer Bird Curator, Al Wabra Wildlife Preservation. Presentation for Aviary Congress Singapore, November 2008 Introduction to Birds of Paradise in the Wild Taxonomy The family Paradisaeidae is in the order Passeriformes. In the past decade since the publication of Frith and Beehler (1998), the taxonomy of the family Paradisaeidae has been re-evaluated considerably. Frith and Beehler (1998) listed 42 species in 17 genera. However, the monotypic genus Macgregoria (MacGregor’s Bird of Paradise) has been re-classified in the family Meliphagidae (Honeyeaters). Similarly, 3 species in 2 genera (Cnemophilus and Loboparadisea) – formerly described as the “Wide-gaped Birds of Paradise” – have been re-classified as members of the family Melanocharitidae (Berrypeckers and Longbills) (Cracraft and Feinstein 2000). Additionally the two genera of Sicklebills (Epimachus and Drepanornis) are now considered to be combined as the one genus Epimachus. These changes reduce the total number of genera in the family Paradisaeidae to 13. However, despite the elimination of the 4 species mentioned above, 3 species have been newly described – Berlepsch's Parotia (P. berlepschi), Eastern or Helen’s Parotia (P. helenae) and the Eastern or Growling Riflebird (P. intercedens). The Berlepsch’s Parotia was once considered to be a subspecies of the Carola's Parotia. It was previously known only from four female specimens, discovered in 1985. It was rediscovered during a Conservation International expedition in 2005 and was photographed for the first time. The Eastern Parotia, also known as Helena's Parotia, is sometimes considered to be a subspecies of Lawes's Parotia, but differs in the male’s frontal crest and the female's dorsal plumage colours. -
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). -
Papua New Guinea Huon Peninsula Extension I 25Th to 30Th June 2019 (6 Days) Trip Report
Papua New Guinea Huon Peninsula Extension I 25th to 30th June 2019 (6 days) Trip Report Huon Astrapia by Holger Teichmann Trip report compiled by Tour Leader: Adam Walleyn Rockjumper Birding Tours www.rockjumperbirding.com Trip Report – RBL Papua New Guinea Huon Extension I 2019 2 Tour in Detail Our group met up in Port Moresby for the late morning flight to Lae’s Nadzab airport. 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. -

Both lineages are shared by Australia and New Guinea. Patternsof latitudinal and altitudinal allopatry and sequencesof introgressiveintergradation are concordantwith these groupings,but many featuresof external morphologyare not. Apparent homologiesin face, wing and tail markings, used formerly as the principal criteria for grouping species,are particularly at variance and are interpreted either as coinherited ancestraltraits or homo- plasies.

Tropical Birding Tour Report
AUSTRALIA’S TOP END Victoria River to Kakadu 9 – 17 October 2009 Tour Leader: Iain Campbell Having run the Northern Territory trip every year since 2005, and multiple times in some years, I figured it really is about time that I wrote a trip report for this tour. The tour program changed this year as it was just so dry in central Australia, we decided to limit the tour to the Top End where the birding is always spectacular, and skip the Central Australia section where birding is beginning to feel like pulling teeth; so you end up with a shorter but jam-packed tour laden with parrots, pigeons, finches, and honeyeaters. Throw in some amazing scenery, rock art, big crocs, and thriving aboriginal culture you have a fantastic tour. As for the list, we pretty much got everything, as this is the kind of tour where by the nature of the birding, you can leave with very few gaps in the list. 9 October: Around Darwin The Top End trip started around three in the afternoon, and the very first thing we did was shoot out to Fogg Dam. This is a wetlands to behold, as you drive along a causeway with hundreds of Intermediate Egrets, Magpie-Geese, Pied Herons, Green Pygmy-geese, Royal Spoonbills, Rajah Shelducks, and Comb-crested Jacanas all close and very easy to see. While we were watching the waterbirds, we had tens of Whistling Kites and Black Kites circling overhead. When I was a child birder and thought of the Top End, Fogg Dam and it's birds was the image in my mind, so it is always great to see the reaction of others when they see it for the first time. -

Water is a precious resource in the Australian deserts, so watering holes like this one near Georgetown are incredible places for concentrating wildlife. Two of our most bird diverse excursions were on our mornings in this region. Photo by guide Doug Gochfeld. Australia. A voyage to the land of Oz is guaranteed to be filled with novelty and wonder, regardless of whether we’ve been to the country previously. This was true for our group this year, with everyone coming away awed and excited by any number of a litany of great experiences, whether they had already been in the country for three weeks or were beginning their Aussie journey in Darwin. Given the far-flung locales we visit, this itinerary often provides the full spectrum of weather, and this year that was true to the extreme. The drought which had gripped much of Australia for months on end was still in full effect upon our arrival at Darwin in the steamy Top End, and Georgetown was equally hot, though about as dry as Darwin was humid. The warmth persisted along the Queensland coast in Cairns, while weather on the Atherton Tablelands and at Lamington National Park was mild and quite pleasant, a prelude to the pendulum swinging the other way. During our final hours below O’Reilly’s, a system came through bringing with it strong winds (and a brush fire warning that unfortunately turned out all too prescient). -
Bird Abundances in Primary and Secondary Growths in Papua New Guinea: a Preliminary Assessment
Mongabay.com Open Access Journal - Tropical Conservation Science Vol.3 (4):373-388, 2010 Research Article Bird abundances in primary and secondary growths in Papua New Guinea: a preliminary assessment Kateřina Tvardíková1 1 Department of Zoology, Faculty of Biological Science, University of South Bohemia, Branišovská 31, CZ- 370 05 České Budějovice. Email: <[email protected] Abstract Papua New Guinea is the third largest remaining area of tropical forest after the Amazon and Congo basins. However, the growing intensity of large-scale slash-and-burn agriculture and logging call for conservation research to assess how local people´s traditional land-use practices result in conservation of local biodiversity, of which a species-rich and diverse component is the avian community. With this in mind, I conducted a preliminary survey of birds in small-scale secondary plots and in adjacent primary forest in Wanang Conservation Area in Papua New Guinea. I used mist-netting, point counts, and transect walks to compare the bird communities of 7-year-old secondary growth, and neighboring primary forest. The preliminary survey lasted 10 days and was conducted during the dry season (July) of 2008. I found no significant differences in summed bird abundances between forest types. However, species richness was higher in primary forest (98 species) than in secondary (78 species). The response of individual feeding guilds was also variable. Two habitats differed mainly in presence of canopy frugivores, which were more abundant (more than 80%) in primary than in secondary forests. A large difference (70%) was found also in understory and mid-story insectivores. Species occurring mainly in secondary forest were Hooded Butcherbird (Cracticus cassicus), Brown Oriole (Oriolus szalayi), and Helmeted Friarbird (Philemon buceroides).
