Recommended Band Size List Introduction ABBBS Recommended Band Size List Introduction Australian Bird and Bat Banding Scheme Recommended Band Size List - Birds of Australia and its Territories Number 25 – May 2018 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 Census of Australian Vertebrate Species (CAVS) numbers (formerly RAOU numbers) and band sizes as recommended by the Australian Bird and Bat Banding Scheme. CAVS Numbers are to be used in any data submissions to the ABBBS. The list is in four parts: Part 1 is in taxonomic order, based on information in "Systematics and Taxonomy and Species of Australian Birds" (2008) by L. Christidis and W. E. Boles, CSIRO Publishing Collingwood; and “The Directory of Australian Birds: Passerines” (1999) by R. Schodde and I.J. Mason, CSIRO Publishing, Collingwood. Additional current taxonomic information and CAVS numbers were sourced from the Australian Faunal Directory (AFD), Australian Biological Resources Study (ABRS), Department of the Environment and Energy Canberra (https://biodiversity.org.au/afd/search/names/). Albatross and Giant Petrel species are based on the Agreement on the Conservation of Albatrosses and Petrels (ACAP) (https://www.acap.aq/). Part 2 is in alphabetic order of common names, sourced from Christidis and Boles (2008), Schodde and Mason (1999), ACAP and the AFD. The lists include sub-species where these are listed in the AFD, and listed in the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The ABBBS makes no taxonomic decisions; if there is disagreement with any of the species designations or names, please raise this with the AFD administrators. Part 3 is a summary of the numbers banded with each band size in alphabetical order, where more than ten individuals have been banded with the band size listed. This is intended to guide banders in the selection of the most appropriate band size by providing data on the levels of past use of each size. Where a species is absent from this list, it has either been banded in very low numbers (< 10), or not at all. Part 4 is a list of specifications for all bands available from the ABBBS. 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. Part 3 of the band size list gives the numbers banded with each size. For some species, relatively few individuals have been banded and the size is listed with a question mark. In other species, too few birds have been banded to justify a size recommendation and none is made. When banding a species for which there is no recommended size, or where there is some doubt about the correct size, be extremely cautious in choosing a band size and only apply bands in such circumstances if you have the equipment and expertise to remove a band which does not fit properly. When properly fitted, a band should move freely along the tarsus or tibia to which it has been applied, without moving onto the upper or lower joints. Bands should NOT be overlapped to achieve a good fit. K-bands are the only exception to this rule, as they are designed to be overlapped. If you feel that a species requires a new design, or a modfied version of a current band, please contact the ABBBS to discuss your requirements. Bands should never be modified without prior approval. Remember: BANDERS ARE RESPONSIBLE FOR FITTING SUITABLE BANDS TO THE BIRDS THEY BAND IF IN DOUBT, DO NOT BAND IT VARIABILITY IN SPECIES There are several sources of variation which must be accommodated when selecting a band size. Individual variation Many species display enough variation in size that one band size will not fit all individuals. For species known to show such size variation, alternative band sizes are given in brackets. A bracketed size should only be used if the first size proves unsuitable. Great care should be taken when banding these species. A band should only be applied if the bander has the equipment and the expertise to remove the band if the fit is not satisfactory. For extremely variable species, these are marked with ‘V’, all individuals tarsi should be measured prior to banding. Geographic variation Where tarsus size is known to vary geographically within a species, different band sizes are recommended and indicated by an asterix (*). Many raptor species are known to vary in size across their range. Many birds in northern Australia require smaller bands than their southern counterparts. Conversely, Tasmanian birds often need a larger band than their mainland counterparts. The Tasmanian Page 1 ABBBS Recommended Band Size List Introduction form of the Southern Boobook is a notable exception, being smaller than its northern relatives. Banders should be alert for such variation in all widely distributed species Variation between sexes In many species there is a significant size difference between males and females. Where different band sizes are known to be required, the sizes are indicated by ‘M’ for male and ‘F’ for female. Birds, and particularly pulli, of sexually dimorphic species should only be banded if the sexes can be clearly distinguished at the time of banding. Where the sex cannot be determined, the individual must not be banded. Variation with age Great care must be taken when banding nestling birds to make sure that their legs have finished growing. Keep in mind too, that in some species, such as the Frigatebirds, tarsal diameter in chicks may actually exceed that of adults, the excess being lost on fledging. Variation in band placement Bands should generally be placed onto the tarsus. However, some species require that the band be placed on the tibia due to high rates of wear or to increase visibility. These species are marked with the word ‘TIBIA’ after the recommended band size. Summary of variation codes Code Meaning * Varies geographically V Variable species – measure tarsus diameter # Care required – see list below ? Few banded, care required – measure tarsus diameter TIBIA Band size recommend is for placement on the tibia (do not place onto tarsus) M Bands suitable for males only (if sex cannot be determined, do not band) F Bands suitable for females only (if sex cannot be determined, do not band) NIL Some individuals may not be suitable for banding OV Ovalise band (special permission required) RESTRICTED Special permission required to band these species, contact ABBBS. DO NOT BAND The species is not to be banded under any circumstances TRIAL OF BAND INFORMATION REQUIRED Whenever a band is used on a species for which there is no recommended size, or the band used is not recommended for that species, a Trial-of-Band-Size form MUST be submitted to the ABBBS as soon as possible after banding. These reports form the basis for revising the band size list. BANDS REMOVED OR DESTROYED Where badly fitted bands need to be removed; are used for training; are lost; or are destroyed, this must be recorded in your data submission to the ABBBS. Please use species number ‘0’, all age and sex codes ‘U’, the date when the band was lost/destroyed/damaged (or as close as possible), the location code for the site where the band was lost/destroyed/damaged, method code 44 (band lost) or 45 (band destroyed or damaged), and status code 00. If in doubt please contact the ABBBS for advice. BAND SPECIFICATIONS Sizes At present there are over 40 different types of band available for issue for use on birds. The specifications of all available bands are given in Part 4. Of the band designs available, five are intended primarily for use on shorebirds (sizes 03, 04, 05, 06 and 07 in incoloy), three for shearwaters (sizes 16, 37 and 38), one for use on pelicans (size 17), eleven are primarily for parrots (sizes 20, 21, 22, 23, 24, 25, 31, 32, 33, 34 and 36), and one for use on kingfishers or other small birds with short tarsi (size K). Three (sizes 15, 35 and 39) have a special clip design to prevent removal, and are only issued to banders with specific studies. The old butt-end style of size 15 SS bands are no longer issued. Penguin flipper tags are no longer issued for use on this species group (sizes 19, 26, 29, 30), however some have proved to be suitable for other species such as Black-necked Stork. The remaining sizes are for general use. Metals The ABBBS currently uses four different materials for bands as Monel (ML) is no longer manufactured or supplied to banders. However, all Monel sizes previously issued are available in Stainless Steel (SS). The metals are abbreviated in the band list as follows: AY = Alloy AM = Aluminium IN = Incoloy SS = Stainless Steel Each metal has different characteristics including weight, wear resistance, hardness, corrosion resistance, and cost. ALUMINIUM (AM) Page 2 ABBBS Recommended Band Size List Introduction On some species and in some habitats these bands last for many years, but in other situations (such as on some ground- frequenting birds and some marine species) may wear very quickly. Nevertheless, the light weight of aluminium bands can be an important consideration, and cost is relatively low. The ABBBS has been phasing out the use of aluminium bands due to the high rate of wear and the exceptionally long lived nature of Australian species generally.

  • Mount Canobolas Fauna Survey
    MOUNT CANOBOLAS FAUNA SURVEY 24TH – 29th MARCH 2019 1 Introduction Mount Canobolas State Conservation Area The Mount Canobolas State Conservation Area (SCA) Draft Plan of Management begins with the following vision for this reserve: Mount Canobolas State Conservation Area is a sentinel in the landscape. It is a park valued, understood and protected by the community for its uniqueness, biodiversity, visitor experiences, and for the spiritual and cultural connections between people and this special place, now and into the future (OEH 2018). This iconic place is an extinct volcano rising to an altitude of 1397m asl and more than 500m above the surrounding central tablelands landscape. It has great significance for the local Wiradjuri custodians. The ecological values of this place are shaped by its high altitude, volcanic origins, isolation from similar geological formations and the extensive clearing of the surrounding landscape leaving it as a relatively isolated remnant of native vegetation. The presence of sub-alpine communities is particularly noteworthy (OEH 2018). The SCA incorporates an area of 1672 ha. The vegetation communities of the Mt Canobolas SCA have been broadly described and mapped with the following communities defined: 1. Eucalyptus macrorhyncha – E. dives: shrubby open forest and woodland (26% of the SCA) a. E. macrorhyncha dominant in more exposed sites b. E. dives dominant in less exposed sites 2. E. pauciflora – E. dalrympleana: Grassy woodlands and tall open forests (51% of the SCA) a. E. pauciflora – E. canobolensis grassy woodlands b. E. dalrympleana – E. viminalis tall open forests 3. Outcrop low open woodland (E. canobolensis – E. petroc?) and / or shrubs 4.

  • 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.

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.

  • NSW Vagrant Bird Review
    an atlas of the birds of new south wales and the australian capital territory Vagrant Species Ian A.W. McAllan & David J. James The species listed here are those that have been found on very few occasions (usually less than 20 times) in NSW and the ACT, and are not known to have bred here. Species that have been recorded breeding in NSW are included in the Species Accounts sections of the three volumes, even if they have been recorded in the Atlas area less than 20 times. In determining the number of records of a species, when several birds are recorded in a short period together, or whether alive or dead, these are here referred to as a ‘set’ of records. The cut-off date for vagrant records and reports is 31 December 2019. As with the rest of the Atlas, the area covered in this account includes marine waters east from the NSW coast to 160°E. This is approximately 865 km east of the coast at its widest extent in the south of the State. The New South Wales-Queensland border lies at about 28°08’S at the coast, following the centre of Border Street through Coolangatta and Tweed Heads to Point Danger (Anon. 2001a). This means that the Britannia Seamounts, where many rare seabirds have been recorded on extended pelagic trips from Southport, Queensland, are east of the NSW coast and therefore in NSW and the Atlas area. Conversely, the lookout at Point Danger is to the north of the actual Point and in Queensland but looks over both NSW and Queensland marine waters.

    Field Guides Tour Report Australia Part 2 2019 Oct 22, 2019 to Nov 11, 2019 John Coons & Doug Gochfeld For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Water is a precious resource in the Australian deserts, so watering holes like this one near Georgetown are incredible places for concentrating wildlife. Two of our most bird diverse excursions were on our mornings in this region. Photo by guide Doug Gochfeld. Australia. A voyage to the land of Oz is guaranteed to be filled with novelty and wonder, regardless of whether we’ve been to the country previously. This was true for our group this year, with everyone coming away awed and excited by any number of a litany of great experiences, whether they had already been in the country for three weeks or were beginning their Aussie journey in Darwin. Given the far-flung locales we visit, this itinerary often provides the full spectrum of weather, and this year that was true to the extreme. The drought which had gripped much of Australia for months on end was still in full effect upon our arrival at Darwin in the steamy Top End, and Georgetown was equally hot, though about as dry as Darwin was humid. The warmth persisted along the Queensland coast in Cairns, while weather on the Atherton Tablelands and at Lamington National Park was mild and quite pleasant, a prelude to the pendulum swinging the other way. During our final hours below O’Reilly’s, a system came through bringing with it strong winds (and a brush fire warning that unfortunately turned out all too prescient).
