Growth Patterns of Hawaiian Stilt Chicks
Wilson Bull., 11 l(4), 1999, pp. 478487 GROWTH PATTERNS OF HAWAIIAN STILT CHICKS J. MICHAEL REED,,2,8‘ ELIZABETH M. GRAY,334 DIANNE LEWIS3 LEWIS W. ORING,3 RICHARD COLEMAN,5 TIMOTHY BURR,6 AND PETER LUSCOMB7 ABSTRACT-We studied chick growth and plumage patterns in the endangered Hawaiian Stilt (Himantopus mexicanus knudseni). Body mass of captive chicks closely fit a Gompertz growth curve, revealing a growth coefficient (K) of 0.065 day- ’ and point of inflection (T) of 17 days. When chicks fledged about 28 days after hatching, they weighed only 60% of adult body mass; at 42 d, birds still were only 75% of adult mass; culmen, tarsus, and wing chord at fledging also were less than adult size. This trend of continued growth to adult size after fledging is typical for most shorebirds. After hatching, captive chicks grew more rapidly than wild chicks, probably because of an unlimited food supply. We found no evidence for adverse effects of weather on the growth of wild chicks. As with other shorebirds, the tarsus started relatively long, with culmen and then wing chord growing more rapidly in later development. Tarsal and wing chord growth were sigmoidal, whereas culmen growth was linear. We describe plumage characteristics of weekly age classes of chicks to help researchers age birds in the wild. Received 28 Dec. 1998, accepted 20 April 1999. Avian growth patterns have been studied (Himantopus mexicanus knudseni), a precocial primarily because of their relationships to the bird that is an endangered subspecies of the ecology and evolutionary history of different Black-necked Stilt. -
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. Collar (2014); 2. -
Of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds
B BIO VIEW Curator Notes From the Brink of Extinct Rebuilding the Socorro Dove Population by Peter Shannon, Rio Grande Zoo Curator of Birds In terms of conservation efforts, the Rio Grande Zoo is a rare breed in its own right, using its expertise to preserve and breed species whose numbers have dwindled to almost nothing both in the wild and in captivity. Recently, we took charge of a little over one-tenth of the entire world’s population of Socorro doves which have been officially extinct in the wild since 1978 and are now represented by only 100 genetically pure captive individuals that have been carefully preserved in European institutions. Of these 100 unique birds, 13 of them are now here at RGZ, making us the only holding facility in North America for this species and the beginning of this continent’s population for them. After spending a month in quarantine, the birds arrived safe and sound on November 18 from the Edinburgh and Paignton Zoos in England. Other doves have been kept in private aviaries in California, but have been hybridized with the closely related mourning dove, so are not genetically pure. History and Background Socorro doves were once common on Socorro Island, the largest of the four islands making up the Revillagigedo Archipelago in the East- ern Pacific ocean about 430 miles due west of Manzanillo, Mexico and 290 miles south of the tip of Baja, California. Although the doves were first described by 19th century American naturalist Andrew Jackson Grayson, virtually nothing is known about their breeding behavior in the wild. -
The Impact of Predation by Introduced Mammals on Endemic Shorebirds in New Zealand: a Conservation Perspective
Biological Conservation 99 (2001) 47±64 www.elsevier.com/locate/biocon The impact of predation by introduced mammals on endemic shorebirds in New Zealand: a conservation perspective John E. Dowding a,*, Elaine C. Murphy b aPO Box 36-274, Merivale, Christchurch 8030, New Zealand bScience and Research Unit, Department of Conservation, Private Bag 4715, Christchurch, New Zealand Abstract The avifauna of New Zealand has been severely depleted since human colonisation and currently contains a disproportionately high number of threatened species. Of the 23 threatened shorebird species worldwide, six are endemic to New Zealand. We review the status of New Zealand's endemic shorebirds and examine the impact on them of various threats, particularly predation by introduced mammals. The conservation status of the 10 extant species (three oystercatchers, one stilt, four plovers and two snipe) is outlined and the factors that predisposed them to predation by introduced mammals are summarised. Individual species accounts are presented, including data on population trends, known or suspected impacts of predation, identi®cation of important predator species, other threats, and conservation measures currently in place or required. One species and two subspecies are extinct, three species are con®ned to predator-free islands and another is found only on the Chatham Islands group. Six survive on the mainland but three have declined to varying degrees and are assigned threatened status by Collar et al. (1994). Only one plover and two oystercatchers are still relatively numerous and/or widespread. Rats, cats and mustelids have had the greatest overall impacts. Conservation measures in place to mitigate the eects of introduced predators include the formulation of recovery plans, predator control around breeding areas, captive breeding and rearing programmes and the founding of new populations by translocation. -

They feature prominently in folklore, mythology and other belief systems of the indigenous people of the region, and are of ecological and conservation value, some species supporting significant (albeit often illegal) economic activities (primarily, the snake-skin trade, but also sale of meat and other body parts that purportedly have medicinal properties). -

Species Account
REPTILIA Order OPHIDIA (Snakes) I. Family COLUBRIDAE Ahaetulla prasina Green Vine Snake This snake was found in Renah Kayu Embun and Napal Licin survey sites at elevation 1400 meters asl and 300 meters asl respectively. Usually it can be seen in degraded habitat including plantation, secondary growth and house compounds, to primary rain forest (Inger and Stuebing, 2005; Kurniati, 2003). It occurs from lowlands up to mountain forests over 1500 meters asl (Kurniati et al., 2001; Kurniati, 2003). It is common species at low elevation (Inger and Stuebing, 2005), but become rare at high elevation such as Renah Kayu Embun survey site. This species is known from South-east Asia, East Indies (Sulawesi and The Lesser Sunda) (Stuebing and Inger, 1999: de Lang and Vogel, 2005). Figure 91. A. prasina (Photograph by H. Kurniati). Amphiesma sp This undescribed snake was found in Muara Labuh survey site at elevation 800 meters asl. It was a nocturnal snake that inhabited strong moving stream bank. The morphology of this snake is similar to A. kerinciense (David and Das, 2003). Possibly, it is a new species, but future study is needed. Figure 92. Amphiesma sp from Muara Labuh (Photograph by H. Kurniati). Aplopeltura boa Blunt-headed Tree Snake This snake was found in Upper Rupit River and Tapan survey sites at elevation 150 meters asl and 550 meters asl respectively. It inhabited lowland primary rain forest. It occurs at elevation between sea level to 1200 meters asl (Kurniati, 2003), but it is confined to be lowland. In Tapan survey site, it was rarely observed. -

The pre-trip was aiming to climb to the top of 2 BirdQuest Tour Report: West Papua Expedition www.birdquest-tours.com Mount Trikora in the Snow Mountains, but because of recent rioting and civil unrest (whereby several dozen people had been killed), access to the town of Wamena was totally denied to foreign visitors by the authorities. So, sadly, no Snow Mountain Robin… We did manage to visit the famous Wasur National Park, which produced the fantastic Spangled Kookaburra and Grey-crowned and Black Mannikins (all Birdquest lifers) and we reached the island of Kofiau, where the fabulous Kofiau Paradise Kingfisher and the modestly- plumaged Kofiau Monarch (two more Birdquest lifers) showed extremely well. The fabulous lowland rainforest site of Malagufuk gave us a long list of exquisite species amongst which a truly impressive Northern Cassowary, a cute Wallace’s Owlet-nightjar, a sublime Papuan Hawk-Owl and a tremendous Red- breasted Paradise Kingfisher stood out. Kingfishers especially performed extremely well on this tour as we saw no fewer than 15 species, including marvels like Hook-billed, Common Paradise, Blue-black, Beach, Yellow-billed and Papuan Dwarf Kingfishers and Blue-winged and Rufous-bellied Kookaburras. -
