Effects of Nestling Diet on Growth and Adult Size of Zebra Finches (Poephila Guttata )
THE AUK A QUARTERLY JOURNAL OF ORNITHOLOGY VOL. 104 APRIL 1987 NO. 2 EFFECTS OF NESTLING DIET ON GROWTH AND ADULT SIZE OF ZEBRA FINCHES (POEPHILA GUTTATA ) PETER T. BOAG Departmentof Biology,Queen's University, Kingston, Ontario K7L 3N6, Canada Al•STRACT.--Manipulationof the diet of Zebra Finch (Poephilaguttata) nestlings in the laboratoryshowed that a low-quality diet reducedgrowth ratesof nine externalmorpholog- ical characters,while a high-quality diet increasedgrowth rates.The growth of plumage characterswas least affectedby diet, while growth ratesof tarsusand masswere most af- fected. The treatments also produced differencesin the adult size of experimental birds, differencesnot evident in either their parentsor their own offspring.Diet quality had the strongestimpact on adult massand tarsuslength, while plumage and beak measurements were less affected. Analysis using principal componentsand characterratios showed that the shapeof experimentalbirds was affectedby the experimentaldiets, but to a minor extent comparedwith changesin overall size. Significantshape changes involved ratiosbetween fast- and slow-growingcharacters. The ratios of charactersthat grow at similar, slow rates (e.g. beak shape) were not affected by the diets.

The Role of Intense Nest Predation in the Decline of Scarlet Robins and Eastern Yellow Robins in Remnant Woodland Near Armidale, New South Wales
The role of intense nest predation in the decline of Scarlet Robins and Eastern Yellow Robins in remnant woodland near Armidale, New South Wales S. J. S. DEBDSI A study of open-nesting Eastern Yellow Robins Eopsaltria australis and Scarlet Robins Petroica multicolor, on the New England Tablelands of New South Wales in 2000-02, found Iow breeding success typical of eucalypt woodland birds. The role of intense nest predation in the loss of birds from woodland fragments was investigated by means of predator-exclusion cages at robin nests, culling of Pied Currawongs Strepera graculina, and monitoring of fledging and recruitment in the robins. Nest-cages significantly improved nest success (86% vs 20%) and fledging rate (1.6 vs 0.3 fledglings per attempt) for both robin species combined (n = 7 caged, 20 uncaged). For both robin species combined, culling of currawongs produced a twofold difference in nest success (33% vs 14%), a higher fledging rate (0.5 vs 0.3 per attempt), and a five-day difference in mean nest survival (18 vs 13 days) (n = 62 nests), although sample sizes for nests in the cull treatment (n = 18) were small and nest predation continued. Although the robin breeding population had not increased one year after the cull, the pool of Yellow Robin recruits in 2001-03, after enhanced fledging success, produced two emigrants to a patch where Yellow Robins had become extinct. Management to assist the conservation of open-nesting woodland birds should address control of currawongs. Key words: Woodland birds, Habitat fragmentation, Nest predation, Predator exclusion, Predator removal. -
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.

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). -

Southwest Pacific Islands: Samoa, Fiji, Vanuatu & New Caledonia Trip Report 11th to 31st July 2015 Orange Fruit Dove by K. David Bishop Trip Report - RBT Southwest Pacific Islands 2015 2 Tour Leaders: K. David Bishop and David Hoddinott Trip Report compiled by Tour Leader: K. David Bishop Tour Summary Rockjumper’s inaugural tour of the islands of the Southwest Pacific kicked off in style with dinner at the Stamford Airport Hotel in Sydney, Australia. The following morning we were soon winging our way north and eastwards to the ancient Gondwanaland of New Caledonia. Upon arrival we then drove south along a road more reminiscent of Europe, passing through lush farmlands seemingly devoid of indigenous birds. Happily this was soon rectified; after settling into our Noumea hotel and a delicious luncheon, we set off to explore a small nature reserve established around an important patch of scrub and mangroves. Here we quickly cottoned on to our first endemic, the rather underwhelming Grey-eared Honeyeater, together with Nankeen Night Herons, a migrant Sacred Kingfisher, White-bellied Woodswallow, Fantailed Gerygone and the resident form of Rufous Whistler. As we were to discover throughout this tour, in areas of less than pristine habitat we encountered several Grey-eared Honeyeater by David Hoddinott introduced species including Common Waxbill. And so began a series of early starts which were to typify this tour, though today everyone was up with added alacrity as we were heading to the globally important Rivierre Bleu Reserve and the haunt of the incomparable Kagu. We drove 1.3 hours to the reserve, passing through a stark landscape before arriving at the appointed time to meet my friend Jean-Marc, the reserve’s ornithologist and senior ranger. -

The Vocal Behavior of the American Crow, Corvus Brachyrhynchos
THE VOCAL BEHAVIOR OF THE AMERICAN CROW, CORVUS BRACHYRHYNCHOS THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Sciences in the Graduate School of The Ohio State University By Robin Tarter, B.S. ***** The Ohio State University 2008 Masters Examination Committee Approved by Dr. Douglas Nelson, Advisor Dr. Mitch Masters _________________________________ Dr. Jill Soha Advisor Evolution, Ecology and Organismal Biology Graduate Program ABSTRACT The objective of this study was to provide an overview of the vocal behavior of the American crow, Corvus brachyrhynchos, and to thereby address questions about the evolutionary significance of crow behavior. I recorded the calls of 71 birds of known sex and age in a family context. Sorting calls by their acoustic characteristics and behavioral contexts, I identified and hypothesized functions for 7 adult and 2 juvenile call types, and in several cases found preferential use of a call type by birds of a particular sex or breeding status. My findings enrich our understanding of crow social behavior. I found that helpers and breeders played different roles in foraging and in protecting family territories from other crows and from predators. My findings may also be useful for human management of crow populations, particularly dispersal attempts using playbacks of crows’ own vocalizations. ii ACKNOWLEDGEMENTS I would like to thank Dr. Kevin McGowan of Cornell, Dr. Anne Clark of Binghamton University, and Binghamton graduate student Rebecca Heiss for allowing me to work with their study animals. McGowan, Clark and Heiss shared their data with me, along with huge amounts of information and insight about crow behavior.
