It is a sexually dimorphic species, the male having a glossy black crown and the female a grey one. The bill of the female is also slightly shorter (about 23 mm for the female as opposed to abodt 26 mm for the male). 1n juveniles the heed is olive and underparts fawn; , . A staccato piping trill is often the first indication of the bird1s presence, being a verbose bird to say the least. The ES gives an impression of being a bird on the move, generally flitting about in rapid steps between flowering plants. It appears appreciative of a bird bath or shower in the hose in dry times, . - .

  • New England Peppermint (Eucalyptus Nova-Anglica) Grassy
    Advice to the Minister for Sustainability, Environment, Water, Population and Communities from the Threatened Species Scientific Committee on an Amendment to the List of Threatened Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Name of the ecological community New England Peppermint (Eucalyptus nova-anglica) Grassy Woodlands This advice follows the assessment of two public nominations to list the ‘New England Peppermint (Eucalyptus nova-anglica) Woodlands on Sediment on the Northern Tablelands’ and the ‘New England Peppermint (Eucalyptus nova-anglica) Woodlands on Basalt on the Northern Tablelands’ as threatened ecological communities under the EPBC Act. The Threatened Species Scientific Committee (the Committee) recommends that the national ecological community be renamed New England Peppermint (Eucalyptus nova-anglica) Grassy Woodlands. The name reflects the fact that the definition of the ecological community has been expanded to include all grassy woodlands dominated or co-dominated by Eucalyptus nova-anglica (New England Peppermint), in New South Wales and Queensland. Also the occurrence of the ecological community extends beyond the New England Tableland Bioregion, into adjacent areas of the New South Wales North Coast and the Nandewar bioregions. Part of the national ecological community is listed as endangered in New South Wales, as ‘New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion’ (NSW Scientific Committee, 2003); and, as an endangered Regional Ecosystem in Queensland ‘RE 13.3.2 Eucalyptus nova-anglica ± E. dalrympleana subsp. heptantha open-forest or woodland’ (Qld Herbarium, 2009). 2. Public Consultation A technical workshop with experts on the ecological community was held in 2005.

Email: [email protected] 272 Axiom Way, Acton Park TAS 7021, Australia. Email: [email protected] Abstract. Annual spring surveys between 2010 and 2016 in a 5000-ha area in the Gloucester Tops in New South Wales recorded 71 bird species. All the study area was at altitudes >1100 m. The monitoring program was carried out with involvement of a team of volunteers, who regularly surveyed 21 1-km transects, for a total of 289 surveys. The study area was within the Barrington Tops and Gloucester Tops Key Biodiversity Area (KBA). The trigger species for the KBA listing was the Rufous Scrub-bird Atrichornis rufescens, which was found to have a widespread distribution in the study area, with an average Reporting Rate (RR) of 56.5%. Another species cited in the KBA nomination, the Flame Robin Petroica phoenicea, had an average RR of 12.6% but with considerable annual variation. Although the Flame Robin had a widespread distribution, one-third of all records came from just two of the 21 survey transects. Thirty-seven bird species had RRs >4% in the study area and were distributed across many transects. Of these, 20 species were relatively common, with RRs >20%, and they occurred in all or nearly all of the survey transects. Introduction shrubs such as Banksia species (Binns 1995).

  • Conserving Migratory and Nomadic Species
    Conserving migratory and nomadic species Claire Alice Runge A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Biological Sciences Abstract Migration is an incredible phenomenon. Across cultures it moves and inspires us, from the first song of a migratory bird arriving in spring, to the sight of thousands of migratory wildebeest thundering across African plains. Not only important to us as humans, migratory species play a major role in ecosystem functioning across the globe. Migratory species use multiple landscapes and can have dramatically different ecologies across their lifecycle, making huge contributions to resource fluxes and nutrient transport. However, migrants around the world are in decline. In this thesis I examine our conservation response to these declines, exploring how well current approaches account for the unique needs of migratory species, and develop ways to improve on these. The movements of migratory species across time and space make their conservation a multidimensional problem, requiring actions to mitigate threats across jurisdictions, across habitat types and across time. Incorporating such linkages can make a dramatic difference to conservation success, yet migratory species are often treated for the purposes of conservation planning as if they were stationary, ignoring the complex linkages between sites and resources. In this thesis I measure how well existing global conservation networks represent these linkages, discovering major gaps in our current protection of migratory species. I then go on to develop tools for improving conservation of migratory species across two areas: prioritizing actions across species and designing conservation networks. Protected areas are one of our most effective conservation tools, and expanding the global protected area estate remains a priority at an international level.

    DAVID BISHOP BIRD TOURS Papua New Guinea 2014 Leader: David Bishop Compiled By: David Bishop Adult male Wattled Ploughbill K. David Bishop David Bishop Bird Tours 2014 David Bishop Bird Tours Papua New Guinea and NE Queensland March 20 – April 6, 2014 Leader: David Bishop This bespoke tour was specially designed to seek out some very distinctive, elusive families and near-families in addition to as many as possible of the distinctive genera. In this and just about everything else I think it fair to say we were enormously successful. This was in no small part due to Tim’s skill in the field and general diligence plus some fine help in from the likes of Leonard, Daniel, Sam and Max. Undoubtedly this was one of the most thoroughly enjoyable and stimulating tours I have ever operated. We both learnt a great deal, for me not least that birding in PNG during late March and early April makes a very pleasant and productive change from the more traditional months. Needless to say we shared a great deal of fun in addition to enjoying some truly spectacular birds, landscape as well some fine cultural experiences. Despite PNG’s sometimes, insalubrious reputation, the people are undoubtedly among the most friendly and fascinating peoples on our planet. Just a handful of this tour’s highlights included: An enormous adult male Southern Cassowary permitted a very close encounter for 30 minutes at Cassowary House – I do believe New Guineans are correct in NOT classifying this beast as a bird! One of the very best day’s birding I can ever recall in Varirata National Park.

  • Chapter 1 LITERATURE REVIEW 1.1 Nectarivore Communities
    Chapter 1 LITERATURE REVIEW 1.1 Nectarivore communities There is considerable debate regarding the role of competition in producing patterns of niche partitioning in ecological communities (e.g. Connell 1983; Roughgarden 1983; Simberloff 1983; Stong Jr. 1983; Mac Nally 1995; Walter and Paterson 1995; Wisheu 1998; Gordon 2000; Mac Nally 2000). Competition is thought to refine the niche of a species when two or more species compete for some resource that is limiting. Natural selection favours conspecifics that compete less with individuals of other species, tending to widen any niche separation between the competing species. There are a number of lines of argument against niches being competitively structured: individualistic, logical structure and lack of field evidence (Gordon 2000). The individualistic argument suggests that species have individual tolerances, preferences and limitations in relation to environmental gradients that govern their distribution and abundance, not pressure from sympatric species (e.g. Stong Jr. 1983). The logical structure argument attacked the idea of competitively structured communities, suggesting that studies had failed to adequately discount a ‘null’ hypothesis that communities are actually assembled at random from species in a regional pool (e.g. Simberloff 1983). Finally, reviews of field evidence suggested that other factors are more important in limiting the growth of natural populations, such as predation, parasites and environmental heterogeneity (e.g. Connell 1983). Despite the arguments of the previous paragraph, studies of nectarivore communities usually invoke competition as the driving force behind community organisation (e.g. Keast 1968a; Ford and Paton 1976b; Lyon 1976; Ford 1977; Ford and Paton 1977; Ford 1979; Feinsinger et al.

On average,birds living in relativelylower rainfall areas (<760 mm annually)lived 15% longer than birdsliving in higher rainfall areas(>760 mm). Out of 18 speciesexamined, only three do not conform with this general trend.

The survival of various organisms,including birds, is related to body mass (Calder 1984, Dobson 1990), although other life history traits may have a considerable influence on survival (Stearns 199:2) Body massof individuals is positively correlated with survival when considered at an interspecific level (Calder 1984), although within speciesthe picture is less clear. Survival is also related to clutch size and total reproductive effort, both of which vary geographicallyand between habitats (e.g., Dob- son 1990).
