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. -
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. -
West Papua Expedition
The fabulous Spangled Kookaburra was one of the many highlights (Mark Van Beirs) WEST PAPUA EXPEDITION 22/28 OCTOBER – 10 NOVEMBER 2019 LEADER: MARK VAN BEIRS 1 BirdQuest Tour Report: West Papua Expedition www.birdquest-tours.com The cracking Kofiau Paradise Kingfisher posed ever so well (Mark Van Beirs) This unusual trip was set up to fill in some of the remaining gaps in the Birdquest New Guinea lifelist, so the plan was to visit several hard to reach venues in West Papua. 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. -

The Maintenance and Reproductive Behaviour of Black Stilts (Himantopus novaezealandiae) in Captivity, and Implications for the Management of this Rare Species. A Thesis Presented in Partial Fulfilment of the Requirements for the Degree of Master of Science in Zoology at Massey University Christine Elva Margaret Reed February 1986 ii ABSTRACT In an effort to conserve New Zealand's rarest endemic wading species, the black stilt (Himantopus novaezealandiae), eggs were removed from the wild in October 1979 for establishment of a captive breeding population. Eight chicks fledged following artificial incubation and hand-rearing at the National Wildlife Centre near Masterton. At two years of age, these tentatively sexed stilts were formed into pairs and housed in large outdoor enclosures. I studied their behaviour from December 1982 until February 1986, aiming to i) collate an ethogram for the species under the restrictions of a captive environment ii) describe and quantify behavioural activity, especially that of reproductive behaviour and breeding biology iii) describe vocalisations and iv) on the basis of observed behaviour, examine captive breeding as a management option for black stilts. A repertoire of 38 context-specific behavioural patterns were observed throughout the year and a further 15 stereo-typed species-typical nest-building, copulatory, incubation and chick-rearing patterns occurred during the breeding season. Time-budget analysis of a focal pair of stilts showed foraging and immobility to be the predominant daily activities, peaking during the pre-nesting period. -

Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional signifi- cance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence - or lack thereof - for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well as anti-parasite behaviors. In some cases, we present original data from our own recent work. We make recommendations for future studies that could im- prove our understanding of this poorly known aspect of avian biology.
