Tricky Birds of Central Victoria - Raptors Tricky birds of central Victoria - raptors Connecting Country 24th August 2020 Geoff Park It’s a hawk! What is a raptor? • Birds of prey, also known as raptors, are birds that hunt or feed on other animals • The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force) • Raptors have keen vision that allows them to detect prey during flight and powerful talons and beaks. In most cases, the females are larger than the males. In ornithology, the term raptor, refers to the following families: Diurnal birds of prey • Accipitridae: hawks, eagles, buzzards, harriers, kites and Old World vultures • Pandionidae: the osprey • Sagittariidae: the secretary bird • Falconidae: falcons and caracaras Nocturnal birds of prey • Strigidae: typical owls • Tytonidae: barn owls Because of their predatory nature they face distinct conservation concerns.

  • Observations on the Raptor Community of the Pilbara Region of Western Australia
    129 AUSTRALIAN FIELD ORNITHOLOGY 2011, 28, 129–132 Observations on the Raptor Community of the Pilbara Region of Western Australia A.J.G. SUTTON 157 Nawaday Way, Singleton, New South Wales 2330 (Email: [email protected]) Summary Fourteen species of diurnal raptor were observed during roadside surveys and nest searches of the Newman district, in the eastern Pilbara region of arid north-western Australia, in 1987–88. Breeding data (months in which nestlings were present) are presented for eight of these species, and dietary observations or pellet analyses are presented for five. Raptor community structure, particularly with respect to bird-eating falcons in various size-classes, appeared similar to that elsewhere in the arid zone. Introduction There has been only one detailed study of the diurnal raptor community in the Australian arid zone, in the south-west of the Northern Territory (Aumann 2001a–d). Otherwise, apart from historical annotated bird or raptor lists for parts of the arid zone, there has been one other study of diurnal raptors, in arid north- eastern South Australia (Falkenberg et al. 2000; Falkenberg 2011), and an anecdotal account of some of the raptors at sites also in arid South Australia (Debus et al. 2006). This paper presents the results of road-transect surveys and nest searches for raptors in arid north-western Australia, obtained during a study on the Grey Falcon Falco hypoleucos (see Sutton 2011). Study area and methods The study area was that part of the Pilbara region within a 100-km radius of Newman (23°21′S, 119°43′E), in the Ophthalmia Range off the eastern Hamersley Range in arid north-western Western Australia (see Sutton 2011 for further details and references).

The thesis may not be reproduced elsewhere without the permission of the Author. THE ECOLOGICAL REQUIREMENTS OF THE NEW ZEALAND FALCON (Falco novaeseelandiae) IN PLANTATION FORESTRY A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Zoology at Massey University, Palmerston North, New Zealand Richard Seaton 2007 Adult female New Zealand falcon. D. Stewart 2003. “The hawks, eagles and falcons have been an inspiration to people of all races and creeds since the dawn of civilisation. We cannot afford to lose any species of the birds of prey without an effort commensurate with the inspiration of courage, integrity and nobility that they have given humanity…If we fail on this point, we fail in the basic philosophy of feeling a part of our universe and all that goes with it.” Morley Nelson, 2002. iii iv ABSTRACT Commercial pine plantations made up of exotic tree species are increasingly recognised as habitats that can contribute significantly to the conservation of indigenous biodiversity in New Zealand. Encouraging this biodiversity by employing sympathetic forestry management techniques not only offers benefits for indigenous flora and fauna but can also be economically advantageous for the forestry industry. The New Zealand falcon (Falco novaeseelandiae) or Karearea, is a threatened species, endemic to the islands of New Zealand, that has recently been discovered breeding in pine plantations. This research determines the ecological requirements of New Zealand falcons in this habitat, enabling recommendations for sympathetic forestry management to be made.

  • 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.

  • Birding Oxley Creek Common Brisbane, Australia
    Birding Oxley Creek Common Brisbane, Australia Hugh Possingham and Mat Gilfedder – January 2011 [email protected] www.ecology.uq.edu.au 3379 9388 (h) Other photos, records and comments contributed by: Cathy Gilfedder, Mike Bennett, David Niland, Mark Roberts, Pete Kyne, Conrad Hoskin, Chris Sanderson, Angela Wardell-Johnson, Denis Mollison. This guide provides information about the birds, and how to bird on, Oxley Creek Common. This is a public park (access restricted to the yellow parts of the map, page 6). Over 185 species have been recorded on Oxley Creek Common in the last 83 years, making it one of the best birding spots in Brisbane. This guide is complimented by a full annotated list of the species seen in, or from, the Common. How to get there Oxley Creek Common is in the suburb of Rocklea and is well signposted from Sherwood Road. If approaching from the east (Ipswich Road side), pass the Rocklea Markets and turn left before the bridge crossing Oxley Creek. If approaching from the west (Sherwood side) turn right about 100 m after the bridge over Oxley Creek. The gate is always open. Amenities The main development at Oxley Creek Common is the Red Shed, which is beside the car park (plenty of space). The Red Shed has toilets (composting), water, covered seating, and BBQ facilities. The toilets close about 8pm and open very early. The paths are flat, wide and easy to walk or cycle. When to arrive The diversity of waterbirds is a feature of the Common and these can be good at any time of the day.

    3.79 31 Field Notes on the Black Falcon By GEORGE W. BEDGGOOD, Lindenow South, Victoria, 3866. Because of the dearth of published records for Falco subniger in Victoria and southern New South Wales, I have summarised all my observations from 1955 to 1978. Wheeler ( 1967) lists it as "rather rare" but records it for all districts of Victoria. Although a bird of the drier inland plains, its nomadic wanderings may result in unexpected appearances outside its normal range. Factors affecting a regular food supply, such as drought, no doubt are responsible for such movements. Because its non-hunting flight is so "crow-like" it could easily be mistaken as "a corvid". The dark sooty-brown plumage which appears black, particularly when the bird is some distance from the observer, or when seen in silhouette, its similar size and general outline could all contribute to mistaken identification. When hunting, its flight is typically falcon-like, swift and calculated. Due to its size and lack of pattern in the plumage it ought not be confused with any other falcon. Between September 1955 and December 1956 I was able to record the species at Jindera, N.S.W., and in Victoria at Bonegilla and Corryong. The Jindera bird was my first experience with the Black Falcon. A farmer travelling in the car and knowing my interest in birds remarked that a pair had been seen frequently in the district. Approaching Jindera we flushed a bird from a telephone post. The farmer immediately identified it as a Black Falcon. It flapped and glided to a windbreak some distance away, its flight no different to that of the many corvids we had passed since leaving Albury.

Vagrants have been widely recorded far from its main migratory routes. Here, we report the occurrence of a Black Kite in the Brazilian Saint Peter and Saint Paul Archipelago (SPSPA) in April/May 2014. The bird remained for 32 days in the SPSPA, disappearing at the end of the rainy season. It looked healthy for most of this period and was once seen preying on a seabird chick.

Population densityincreased from 24 territorial pairs per 100 km'• in 1992 to 38 in 1996. Nearest neighbor distanceswere variable, averaging1288 m for solitary pairs (N = 24) and 306 m for colonial ones (N = 151). Regular spacing of nest siteswas the rule within colonies, but inter-nest distance for solitary breeders increased as new pairs settled in the area. Nests occurred both in trees (58%, N = 84) and on cliffs (42%); 23% and 5% (N = 84) of the nestswere originally built by Common Buzzards (Buteobuteo) and Ravens (C0rvuscorax), respectively. Mean laying date was 25 April (N = 42), mean clutch size was 2.29 eggs (N = 42) and mean number of fledged young was 0.97, 1.11, and 1.78 young per territorial, reproductive, and successfulpairs, respectively(N = 143, 95, 78). The percentageof successfulterritorial pairswas 55% (N = 143). Diet was dominated by fish and birds, which accounted for 62% and 28% of 307 identified prey items, respectively.Compared with other European populations, this population showedan intermediate den- sityand an averageclutch sizebut the lowestfledging and breeding successever recorded for the species.
