  • The Impact of Predation by Introduced Mammals on Endemic Shorebirds in New Zealand: a Conservation Perspective

    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.

Alan Stewart and Lori Sargent ABSTRACT Hunter cooperator surveys, spring breeding surveys, and mail harvest surveys are conducted each year to monitor Ruffed grouse (Bonasa umbellus) and American woodcock (Scolopax minor) populations. Annual data comparisons are described for hunter cooperator survey (2015–2016), Ruffed grouse drumming survey (2015-2016), American woodcock spring breeding surveys (2016-2017), and mail harvest survey (2010-2011). Ruffed grouse cooperators hunting the first 4 days of ruffed grouse season reported an average 1.93 grouse per hour in 2016 compared to 0.91 grouse per hour in 2015. The usual spring drumming grouse surveys were not conducted this year because of concerns over past open records requests from a hunter whose activities jeopardized the validity of the survey. There was an increase detected in Michigan’s woodcock index based on the singing-ground survey from 2016-2017 and during the ten-year trend from 2007-2017. Significant long-term (1968-2017) declines were detected regionally and statewide, respectively. Woodcock banders in Michigan spent 1,950 hours afield in 2017 and banded 937 chicks. There were about 67 chicks observed and 48 chicks banded per 100 hours of search time, compared to 66 chicks observed and 49 banded in 2016. There were 112 ruffed grouse drumming routes surveyed in 2015 and 105 in 2014.

He is interested in the connection between three fields of ecology: behavioral ecology, community ecology and conservation biology. His research focuses on how behavior, particularly communication, affects the interactions between species, and how knowledge about such interactions can be integrated into conservation and management plans. He received his bachelor’s from Harvard College (1997), his Ph.D. from the University of Massachusetts, Amherst (2005), and held postdoctoral fellowships at the Massachusetts Institute for Technology, the National Science Foundation (USA) and the University of California, San Diego / University of San Diego. Much of his work has been done on birds and in Sri Lanka, but he has also conducted bird research in India, Papua New Guinea (PNG), and China, and has also worked on communication in bees. He is the first author of “Mixed-species Animal Groups” (Academic Press, 2017), the only book on this topic, and more than 50 scientific articles including publications in general science journals, such as Trends in Ecology and Evolution, Proceedings of the Royal Society B, American Naturalist, and Biology Letters, animal behavior journals, such as Animal Behavior, and Behavioral Ecology, and conservation/environmental journals, such as Environmental Pollution, Diversity and Distributions, Agriculture, Ecosystems and Environment, and Biological Conservation.

    Conservation Evidence (2006) 3, 79-80 www.ConservationEvidence.com The effectiveness of opening up rush patches on encouraging breeding common snipe Gallinago gallinago at Rogersceugh Farm, Campfield Marsh RSPB reserve, Cumbria, England Holton N. & Allcorn R.I. Royal Society for the Protection of Birds, The Lodge, Sandy, Bedfordshire SG19 2GL, UK SUMMARY An area of improved grassland was dominated by rushes Juncus spp. and purple moor-grass Molinia caerulea . In order to try and attract breeding common snipe Gallinago gallinago , the rush was cut in 2003 with tractor mounted mowers and then grazed. In addition, 18 small scrapes were dug and higher water levels were maintained. The number of snipe increased from one nesting pair in 2003 to 11 nesting pairs in both 2004 and 2005. BACKGROUND Throughout the UK, common snipe Gallinago gallinago are undergoing a large population decline of between 25-49% in both breeding population and range over the last 25 years. Snipe feed by probing for invertebrates deep in soft, damp soil using their long bills. They also require wet marshy grassland areas with tussocks of taller vegetation for nesting. ACTION Figure 1 . All the rush on the improved grassland was cut with tractor mounted mowers. Study site: Rogersceugh Farm in Cumbria, north-west England, is a traditionally managed farm incorporating approximately 60 ha of waist high rush Juncus spp. and purple moor- reclaimed peatland. The RSPB purchased the grass Molinia caerulea . A breeding wader farm in order to raise water levels on the survey was carried out in 2003 prior to the adjacent raised mire whilst at the same time purchase of the farm by the RSPB.
  • Migration Timing, Routes, and Connectivity of Eurasian Woodcock Wintering in Britain and Ireland

    Migration Timing, Routes, and Connectivity of Eurasian Woodcock Wintering in Britain and Ireland

    Migration Timing, Routes, and Connectivity of Eurasian Woodcock Wintering in Britain and Ireland ANDREW N. HOODLESS,1 Game & Wildlife Conservation Trust, Burgate Manor, Fordingbridge, Hampshire SP6 1EF, UK CHRISTOPHER J. HEWARD, Game & Wildlife Conservation Trust, Burgate Manor, Fordingbridge, Hampshire SP6 1EF, UK ABSTRACT Migration represents a critical time in the annual cycle of Eurasian woodcock (Scolopax rusticola), with poten- tial consequences for individual fitness and survival. In October–December, Eurasian woodcock migrate from breeding grounds in northern Eurasia over thousands of kilometres to western Europe, returning in March–May. The species is widely hunted in Europe, with 2.3–3.5 million individuals shot per year; hence, an understanding of the timing of migra- tion and routes taken is an essential part of developing sustainable flyway management. Our aims were to determine the timing and migration routes of Eurasian woodcock wintering in Britain and Ireland, and to assess the degree of connec- tivity between breeding and wintering sites. We present data from 52 Eurasian woodcock fitted with satellite tags in late winter 2012–2016, which indicate that the timing of spring departure varied annually and was positively correlated with temperature, with a mean departure date of 26 March (± 1.4 days SE). Spring migration distances averaged 2,851 ± 165 km (SE), with individuals typically making 5 stopovers. The majority of our sample of tagged Eurasian woodcock migrated to breeding sites in northwestern Russia (54%), with smaller proportions breeding in Denmark, Scandinavia, and Finland (29%); Poland, Latvia, and Belarus (9.5%); and central Russia (7.5%). The accumulated migration routes of tagged individ- uals suggest a main flyway for Eurasian woodcock wintering in Britain and Ireland through Belgium, the Netherlands, and Germany, and then dividing to pass through the countries immediately north and south of the Baltic Sea.
