Here we provide a detailed comparison of the anatomy of Ambiortus relative to other known Early Cretaceous ornithuromorphs from the Chinese Jehol Group and Xiagou Formation. We include new information on Ambiortus from a previously undescribed slab preserving part of the sternum. Ambiortus is superficially similar to Gansus yumenensis from the Aptian Xiagou Forma tion but shares more morphological features with Yixianornis grabaui (Ornithuromorpha: Songlingorni thidae) from the Jiufotang Formation of the Jehol Group. In general, the mosaic pattern of character distri bution among early ornithuromorph taxa does not reveal obvious relationships between taxa. Ambiortus was placed in a large phylogenetic analysis of Mesozoic birds, which confirms morphological observations and places Ambiortus in a polytomy with Yixianornis and Gansus.

Megapodes: an action plan for their conservation 1995 - 1999, a collaborative effort of members of the Megapode Specialist Group and the World Pheasant Association, was published in 1995. It summa- rizes the conservation status of all megapode taxa and indicates the needs of those species under threat. The Action Plan was intended to be a stimulus for conservation orientated studies and to gen- erate funds more easily. An overview is given of studies (1990 - present) in which these threatened taxa were involved. The status of these and other taxa are reassessed according to the finalized IUCN threat categories (which supercede the Mace-Lande threat categories originally used in the Action Plan) as a preparation for the megapode action plan 2000 - 2004. Introduction Megapodes: an action plan for their conservation 1995 - 1999 (Dekker & McGowan, 1995) was published by the Species Survival Commission (SSC) of the International Union for the Conservation of Nature (IUCN) in 1995 following a Conservation Assessment Management Plan (CAMP) meeting on galliforms held in Antwerp, Bel- gium, in February 1993. The megapode action plan, soon followed by action plans for partridges, quails, francolins, snowcocks and guineafowl (McGowan et al., 1995) and pheasants (McGowan & Garson, 1995), was the first avian action plan published by the IUCN in their series of conservation action plans. -
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. Accord- tend to change shape in a way that converges subtly on the flightless ingly, we hypothesize that volant island birds, even those unlikely to form. -

The Chinese Hwamei Garrulax canorus, a member of the family Leiothrichidae, is commonly found in central and southern China, northern Indochina, and on Hainan Island. In this study, we sequenced the complete mitochondrial genome of G. canorus. The circular mitochondrial genome is 17,785 bp in length and includes 13 protein-coding genes, 22 transfer RNA (tRNA) genes, and two ribosomal RNA genes. In addition, two copies of highly Genetics and Molecular Research 14 (3): 8964-8976 (2015) ©FUNPEC-RP www.funpecrp.com.br Mitogenome of Garrulax canorus 8965 similar putative control regions were observed in the mitochondrial genome. As found in other vertebrates, most of the genes are coded on the H-strand, except for one protein-coding gene (nad6; NADH dehydrogenase subunit 6) and eight tRNA genes (tRNAGln, tRNAAla, tRNAAsn, tRNACys, tRNATyr, tRNASer(UCN), tRNAPro, and tRNAGlu). -

Does evolution of plumage patterns and of migratory behaviour in Apodini swifts (Aves: Apodiformes) follow distributional range shifts? Dieter Thomas Tietze, Martin Päckert, Michael Wink The Apodini swifts in the Old World serve as an example for a recent radiation on an intercontinental scale on the one hand. On the other hand they provide a model for the interplay of trait and distributional range evolution with speciation, extinction and trait s t transition rates on a low taxonomic level (23 extant taxa). Swifts are well adapted to a life n i mostly in the air and to long-distance movements. Their overall colouration is dull, but r P lighter feather patches of chin and rump stand out as visual signals. Only few Apodini taxa e r breed outside the tropics; they are the only species in the study group that migrate long P distances to wintering grounds in the tropics and subtropics. We reconstructed a dated molecular phylogeny including all species, numerous outgroups and fossil constraints. Several methods were used for historical biogeography and two models for the study of trait evolution. We finally correlated trait expression with geographic status. The differentiation of the Apodini took place in less than 9 Ma. Their ancestral range most likely comprised large parts of the Old-World tropics, although the majority of extant taxa breed in the Afrotropic and the closest relatives occur in the Indomalayan. The expression of all three investigated traits increased speciation rates and the traits were more likely lost than gained. Chin patches are found in almost all species, so that no association with phylogeny or range could be found. -
BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-Eaters, Babblers, and a Whole Lot More
BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-eaters, Babblers, and a whole lot more A Tropical Birding Set Departure July 1-16, 2018 Guide: Ken Behrens All photos by Ken Behrens TOUR SUMMARY Borneo lies in one of the biologically richest areas on Earth – the Asian equivalent of Costa Rica or Ecuador. It holds many widespread Asian birds, plus a diverse set of birds that are restricted to the Sunda region (southern Thailand, peninsular Malaysia, Sumatra, Java, and Borneo), and dozens of its own endemic birds and mammals. For family listing birders, the Bornean Bristlehead, which makes up its own family, and is endemic to the island, is the top target. For most other visitors, Orangutan, the only great ape found in Asia, is the creature that they most want to see. But those two species just hint at the wonders held by this mysterious island, which is rich in bulbuls, babblers, treeshrews, squirrels, kingfishers, hornbills, pittas, and much more. Although there has been rampant environmental destruction on Borneo, mainly due to the creation of oil palm plantations, there are still extensive forested areas left, and the Malaysian state of Sabah, at the northern end of the island, seems to be trying hard to preserve its biological heritage. Ecotourism is a big part of this conservation effort, and Sabah has developed an excellent tourist infrastructure, with comfortable lodges, efficient transport companies, many protected areas, and decent roads and airports. So with good infrastructure, and remarkable biological diversity, including many marquee species like Orangutan, several pittas and a whole Borneo: Bristleheads and Broadbills July 1-16, 2018 range of hornbills, Sabah stands out as one of the most attractive destinations on Earth for a travelling birder or naturalist. -

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. -

Nomenclature of the Laysan Honeycreeper Himatione [Sanguinea] Fraithii
Peter Pyle 116 Bull. B.O.C. 2011 131(2) Nomenclature of the Laysan Honeycreeper Himatione [sanguinea] fraithii by Peter Pyle Received 21 May 2010 The Apapane Himatione sanguinea is the most abundant extant species of Hawaiian finch (Fringillidae, Drepanidinae) (Pratt 2005, Pyle & Pyle 2009). It occurs throughout high islands of the south-east Hawaiian Islands, where it shows little to no inter-island variation. On Laysan Island, Northwestern Hawaiian Islands, a resident Himatione was first encountered on 3 April 1828 by the naturalist C. Isenbeck (von Kittlitz 1834) and named much later from specimens collected by H. Palmer and G. Munro in June 1891 (Rothschild 1892). While Palmer and Munro were on Laysan they were assisted by George D. Freeth, manager of a guano-mining operation there and an amateur naturalist. In acknowledgement, Rothschild named the new bird Himatione fraithii, based evidently on a miscommunication from Palmer or Munro or an erroneous assumption concerning the spelling of Freeth’s name, which is not mentioned in the description. This taxon, widely known as the Laysan Honeyeater and, later, the Laysan Honeycreeper, became extinct in 1923 (Ely & Clapp 1975, A. Wetmore in Olson 1996). Walter Rothschild was a well-known British zoologist with an avid interest in the birdlife of islands (Rothschild 1983, Olson 2008). He had sent Palmer and other collectors to procure specimens from the Hawaiian Islands in 1890–93 for his private museum in Tring, England. Based upon this collection he published Avifauna of Laysan and the neighbouring islands, with a complete history to date of the birds of the Hawaiian possession in three parts, Part I in August 1893, Part II in November 1893 and Part III in December 1900 (Rothschild 1893– 1900; see Olson 2003). -
