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. Collar (2014); 2. -
The Avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, Including Evidence for Long-Term Population Dynamics in Undisturbed Tropical Forest
Ben Freeman & Alexandra M. Class Freeman 30 Bull. B.O.C. 2014 134(1) The avifauna of Mt. Karimui, Chimbu Province, Papua New Guinea, including evidence for long-term population dynamics in undisturbed tropical forest Ben Freeman & Alexandra M. Class Freeman Received 27 July 2013 Summary.—We conducted ornithological feld work on Mt. Karimui and in the surrounding lowlands in 2011–12, a site frst surveyed for birds by J. Diamond in 1965. We report range extensions, elevational records and notes on poorly known species observed during our work. We also present a list with elevational distributions for the 271 species recorded in the Karimui region. Finally, we detail possible changes in species abundance and distribution that have occurred between Diamond’s feld work and our own. Most prominently, we suggest that Bicolored Mouse-warbler Crateroscelis nigrorufa might recently have colonised Mt. Karimui’s north-western ridge, a rare example of distributional change in an avian population inhabiting intact tropical forests. The island of New Guinea harbours a diverse, largely endemic avifauna (Beehler et al. 1986). However, ornithological studies are hampered by difculties of access, safety and cost. Consequently, many of its endemic birds remain poorly known, and feld workers continue to describe new taxa (Prat 2000, Beehler et al. 2007), report large range extensions (Freeman et al. 2013) and elucidate natural history (Dumbacher et al. 1992). Of necessity, avifaunal studies are usually based on short-term feld work. As a result, population dynamics are poorly known and limited to comparisons of diferent surveys or diferences noticeable over short timescales (Diamond 1971, Mack & Wright 1996). -

A Bush Calendar AMY MACK Margaret Donald (cc by-sa 2.0) The bushland path that through the gully strays, And leads the wanderer into wonderland... PREFACE “A Bush Calendar’’ was commenced with the idea of sharing with other bush lovers the pleasures which I myself have found in my walks, and it ap- peared originally on the Page for Women of the “Sydney Morning Herald.’’ As the seasons advanced letters of en couragement were received from many readers who “knew their Bush’’ and from some who admittedly had not found the key which unlocks the book of Nature; and it is at the request of many of these unknown friends that the articles are reprinted. Although the book is not intended to be a complete scientific record, the lists of flowers and birds most in prominence each month have been so greatly extended that they may claim to be fairly representative of the coastal districts around Sydney. -
Recommended Band Size List Page 1
Jun 00 Australian Bird and Bat Banding Scheme - Recommended Band Size List Page 1 Australian Bird and Bat Banding Scheme Recommended Band Size List - Birds of Australia and its Territories Number 24 - May 2000 This list contains all extant bird species which have been recorded for Australia and its Territories, including Antarctica, Norfolk Island, Christmas Island and Cocos and Keeling Islands, with their respective RAOU numbers and band sizes as recommended by the Australian Bird and Bat Banding Scheme. The list is in two parts: Part 1 is in taxonomic order, based on information in "The Taxonomy and Species of Birds of Australia and its Territories" (1994) by Leslie Christidis and Walter E. Boles, RAOU Monograph 2, RAOU, Melbourne, for non-passerines; and “The Directory of Australian Birds: Passerines” (1999) by R. Schodde and I.J. Mason, CSIRO Publishing, Collingwood, for passerines. Part 2 is in alphabetic order of common names. The lists include sub-species where these are listed on the Census of Australian Vertebrate Species (CAVS version 8.1, 1994). CHOOSING THE CORRECT BAND Selecting the appropriate band to use combines several factors, including the species to be banded, variability within the species, growth characteristics of the species, and band design. The following list recommends band sizes and metals based on reports from banders, compiled over the life of the ABBBS. For most species, the recommended sizes have been used on substantial numbers of birds. For some species, relatively few individuals have been banded and the size is listed with a question mark. In still other species, too few birds have been banded to justify a size recommendation and none is made. -
2020 Dodgy Drongo Twitchathon Report the Drongos Last Won the 30Hr Race Back in 2017 and It Was Great Getting That Team Back Together Again
2020 Dodgy Drongo Twitchathon Report The Drongos last won the 30hr race back in 2017 and it was great getting that team back together again. Maxie the Co-pilot and Simon ‘The Whisperer’ joined the Capt’n for a week of birding out west before heading to our starting point in the mulga. It is here I should mention that the area is currently seeing an absolute boom period after recent rains and was heaving with birds. So with this in mind and with our proven ‘golden route’ we were quite confident of scoring a reasonably good score. We awoke to rain on tin and it didn’t stop as we drove to the mulga, in fact it got heavier.As we sat in the car with 20min until start time we were contemplating if this would kill our run. But as we walked around in the drizzle we soon realised the birds were still active. Simon found a family of Inland Thornbill (a bird I always like to start with), Max had found a roosting Hobby and I’d found some Bee-eaters and Splendid Fairywrens. As the alarm chimed we quickly ticked up all those species as well as Red-capped Robin, Masked and White-browed Woodswallow, Black Honeyeater, White-winged Triller and Budgerigar. The Little Eagle was still on it’s nest and a pair of Plum-headed Finches shot past. We then changed location within the mulga and soon flushed a Little Buttonquail!! Common Bronewing, Owlet-nightjar and Mulga Parrot soon fell and after 20min we were off. -

Attack by a Peregrine Falcon on a Little Eagle on November 25, 1979
AUSTRALIAN 238 \ ARNEY: Peregrine Falcon BIRD WATCHER Attack by a Peregrine Falcon on a Little Eagle On November 25, 1979 whilst inspecting Peregrine Falcon Falco peregrinus eyries at Nowingi, Victoria, in company with Brian Smith, we witnessed an attack by a pair of Peregrines on a Little Eagle Hieraaetus morphnoides. At the time I was participating in the Victorian Fisheries and Wildlife Department's Peregrine Project. Almost immediately after the Little Eagle was disturbed from its perch in a Belar Casuarina cristata it was pursued by the Falcon, closely fol lowed by her mate. Both birds made several passes at the Little Eagle, the Falcon pulling out when within two metres of its prey, and the Tiercel when approximately five metres from it. In the final attack the Falcon actually struck the Little Eagle behind the head, dislodging a few small feathers and causing it to plummet into a wheat crop some 7-10 metres below. Although we made a diligent search for 20 minutes we failed to locate the victim, but to our utter amazement it then rose from the crop in an endeavour to reach the cover of trees about 150 metres distant succeeding just in time to avoid another onslaught by the Falcon. Over the past four years there has been a close associatiOn between these birds, the Peregrines breeding in the nest occupied by the Little Eagles the previous season. At the time of this incident the Peregrine chicks were fledged and witnessed the encounter from a nearby vantage point. It is significant that the incident took place in the vicinity of the nest in which the Little Eagle had recently reared its young, for when I passed it again on August 17, 1980 the Tiercel was indulging in court ship behaviour in the presence of the Falcon perched in the particular nest tree, thus indicating a continuity of the pattern over the previous four years. -

Birdquest Australia (Western and Christmas
Chestnut-backed Button-quail in the north was a bonus, showing brilliantly for a long time – unheard of for this family (Andy Jensen) WESTERN AUSTRALIA 5/10 – 27 SEPTEMBER 2017 LEADER: ANDY JENSEN ASSISTANT: STUART PICKERING ! ! 1 BirdQuest Tour Report: Western Australia (including Christmas Island) 2017 www.birdquest-tours.com Western Shrike-tit was one of the many highlights in the southwest (Andy Jensen) Western Australia, if it were a country, would be the 10th largest in the world! The BirdQuest Western Australia (including Christmas Island) 2017 tour offered an unrivalled opportunity to cover a large portion of this area, as well as the offshore territory of Christmas Island (located closer to Indonesia than mainland Australia). Western Australia is a highly diverse region with a range of habitats. It has been shaped by the isolation caused by the surrounding deserts. This isolation has resulted in a richly diverse fauna, with a high degree of endemism. A must visit for any birder. This tour covered a wide range of the habitats Western Australia has to offer as is possible in three weeks, including the temperate Karri and Wandoo woodlands and mallee of the southwest, the coastal heathlands of the southcoast, dry scrub and extensive uncleared woodlands of the goldfields, coastal plains and mangroves around Broome, and the red-earth savannah habitats and tropical woodland of the Kimberley. The climate varied dramatically Conditions ranged from minus 1c in the Sterling Ranges where we were scraping ice off the windscreen, to nearly 40c in the Kimberley, where it was dust needing to be removed from the windscreen! We were fortunate with the weather – aside from a few minutes of drizzle as we staked out one of the skulkers in the Sterling Ranges, it remained dry the whole time. -
A Review of the Distribution, Status and Ecology of the Star Finch Neochmia Ruficauda in Queensland
AUSTRALIAN 278 BIRD WATCHER AUSTRALIAN BIRD WATCHER 1998, 17, 278-289 A Review of the Distribution, Status and Ecology of the Star Finch Neochmia ruficauda in Queensland by GLENN H.OLMES, P.O. Box 1246, Atherton, Queensland 4883 Summary The Star Finch Neochmia ruficauda has been recorded in 35-37 one-degree blocks in Queensland. Most records concern the Edward River, Princess Charlotte Bay and Rockharnpton districts. Viable populations are probably now restricted to Cape York Peninsula. Typical habitat comprises grasslands or grassy open woodlands, near permanent water or subject to regular inundation. Some sites support shrubby regrowth caused by the clearing of formerly unsuitable denser woodlands. Recorded food items are all seeds, of five grass species and one sedge. Precise nest records are few, but large numbers of juveniles have been observed during the last two decades at Aurukun, Pormpuraaw, Kowanyarna and Princess Charlotte Bay. Threatening processes are discussed; livestock grazing in riparian situations is considered the most deleterious. Introduction The distribution, status and ecology of the Star Finch Neochmia ruficauda in Queensland require urgent review. Endemic to northern and eastern Australia, its populations have declined in most regions. Available evidence suggests that the greatest contraction in its distribution has occurred in Queensland (e.g. Blakers et al. 1984). It is extinct in New South Wales, but its distribution there was only oflirnited extent (Holmes 1996). The Star Finch is protected stringently in Queensland because it is gazetted as Endangered under the Nature Conservation Act 1992. This categorisation takes due account of 'biological vulnerability, extent of current knowledge ... and management needs'. -
