Last spring, while "surf­ NatIlral luaterinfJ bole.for Gouldian Finches in tbe wild. ing" the Internet for Australian bird web sites, I came across a Gouldian Finch site. Michael Fendley, a coordi­ nator of the Threatened Bird Network at the RAOU Head Office in Australia, was looking for volunteers to help count Gouldian Finches in the Northern Territory. My first thought was: Here is my chance! Immediately I sent Mr. Fendley e­ mail indicating that I was interested in volunteering for the survey. The next day I received Mr. Fendley's reply telling me that" he had sent my name to Mr. Peter Dostine, Senior Research Wildlife Officer with the Parks and Wildlife Commission of the Northern Territory in charge of the Gouldian Finch project. Several days later I received a letter Arttficial watering holes lined with black plastic are readily used by the Gouldian Finch in the from Mr. Dostine informing me of lui/d.

  • Phylogeography of Finches and Sparrows
    In: Animal Genetics ISBN: 978-1-60741-844-3 Editor: Leopold J. Rechi © 2009 Nova Science Publishers, Inc. Chapter 1 PHYLOGEOGRAPHY OF FINCHES AND SPARROWS Antonio Arnaiz-Villena*, Pablo Gomez-Prieto and Valentin Ruiz-del-Valle Department of Immunology, University Complutense, The Madrid Regional Blood Center, Madrid, Spain. ABSTRACT Fringillidae finches form a subfamily of songbirds (Passeriformes), which are presently distributed around the world. This subfamily includes canaries, goldfinches, greenfinches, rosefinches, and grosbeaks, among others. Molecular phylogenies obtained with mitochondrial DNA sequences show that these groups of finches are put together, but with some polytomies that have apparently evolved or radiated in parallel. The time of appearance on Earth of all studied groups is suggested to start after Middle Miocene Epoch, around 10 million years ago. Greenfinches (genus Carduelis) may have originated at Eurasian desert margins coming from Rhodopechys obsoleta (dessert finch) or an extinct pale plumage ancestor; it later acquired green plumage suitable for the greenfinch ecological niche, i.e.: woods. Multicolored Eurasian goldfinch (Carduelis carduelis) has a genetic extant ancestor, the green-feathered Carduelis citrinella (citril finch); this was thought to be a canary on phonotypical bases, but it is now included within goldfinches by our molecular genetics phylograms. Speciation events between citril finch and Eurasian goldfinch are related with the Mediterranean Messinian salinity crisis (5 million years ago). Linurgus olivaceus (oriole finch) is presently thriving in Equatorial Africa and was included in a separate genus (Linurgus) by itself on phenotypical bases. Our phylograms demonstrate that it is and old canary. Proposed genus Acanthis does not exist. Twite and linnet form a separate radiation from redpolls.

  • Evolution of the P53-MDM2 Pathway Emma Åberg1, Fulvio Saccoccia1, Manfred Grabherr1, Wai Ying Josefin Ore1, Per Jemth1* and Greta Hultqvist1,2*
    Åberg et al. BMC Evolutionary Biology (2017) 17:177 DOI 10.1186/s12862-017-1023-y RESEARCH ARTICLE Open Access Evolution of the p53-MDM2 pathway Emma Åberg1, Fulvio Saccoccia1, Manfred Grabherr1, Wai Ying Josefin Ore1, Per Jemth1* and Greta Hultqvist1,2* Abstract Background: The p53 signalling pathway, which controls cell fate, has been extensively studied due to its prominent role in tumor development. The pathway includes the tumor supressor protein p53, its vertebrate paralogs p63 and p73, and their negative regulators MDM2 and MDM4. The p53/p63/p73-MDM system is ancient and can be traced in all extant animal phyla. Despite this, correct phylogenetic trees including both vertebrate and invertebrate species of the p53/p63/p73 and MDM families have not been published. Results: Here, we have examined the evolution of the p53/p63/p73 protein family with particular focus on the p53/ p63/p73 transactivation domain (TAD) and its co-evolution with the p53/p63/p73-binding domain (p53/p63/p73BD) of MDM2. We found that the TAD and p53/p63/p73BD share a strong evolutionary connection. If one of the domains of the protein is lost in a phylum, then it seems very likely to be followed by loss of function by the other domain as well, and due to the loss of function it is likely to eventually disappear. By focusing our phylogenetic analysis to p53/p63/ p73 and MDM proteins from phyla that retain the interaction domains TAD and p53/p63/p73BD, we built phylogenetic trees of p53/p63/p73 and MDM based on both vertebrate and invertebrate species.

This study compares stress and condition measures of co-occurring declining and non-declining tropical grass finch species in Australia. We monitored declining Gouldian finches (Erythrura gouldiae) and non-declining long-tailed and masked finches (Poepila acuticauda and P. personata) during two seasons that are potentially stressful: peak breeding (early dry season when food is plentiful) and moult (late dry to early wet season when food may be scarce). We measured body condition (muscle and fat), haematocrit, and stress response to capture using plasma corticosterone and binding globulin concentrations.

  • Northern Territory, Top End
    Northern Territory, Top End Ian Reid and Paul Coddington, 7-16 Aug 2020 Preamble Six or seven years into our Australian sojourn I still had a few birds to collect in the south, but lifers close to home were becoming harder and harder to come by. In contrast, the far north still held bags of new birds. In fact even in pre-birding days growing up in Perth I had never been much beyond the Tropic of Capricorn, so there are vast swathes of Australia waiting for me to explore. In both 2018 and 2019 I had tentative plans to go to NT, but those plans were never realised. In 2020, I had a trip to Peru with UK birding mate Steve lined up, but that was cancelled in June because of covid. With very little birding in the first half of the year largely because of lockdown in SA, and my main birding event for the latter part cancelled, I began to wonder if I’d get any birding at all in 2020. But by early July the signs were good that SA, NT, Tas, WA, and maybe Qld had got their covid outbreaks under control and restrictions and border controls started to relax. The date for opening the NT border was set to 23rd July and I hatched a plan for a week of Top End birding in August once the border had opened and flights resumed. Paul Coddington, my traveling/birding companion on various SA twitches and a couple of outback camping trips, had birded NT in 2014 but missed quite a bit of stuff, so he was keen to join me.

Research Online is the open access institutional repository for the University of Wollongong. For further information contact the UOW Library: [email protected] Condition index monitoring supports conservation priorities for the protection of threatened grass-finch populations Abstract Conservation agencies are often faced with the difficult task of prioritizing what recovery actions receive support. With the number of species under threat of decline growing globally, research that informs conservation priorities is greatly needed. The er lative vulnerability of cryptic or nomadic species is often uncertain, because populations are difficult to monitor and local populations often seem stable in the short term. This uncertainty can lead to inaction when populations are in need of protection. We tested the feasibility of using differences in condition indices as an indication of population vulnerability to decline for related threatened Australian finch ubs -species. The Gouldian finch er presents a relatively well-studied endangered species, which has a seasonal and site-specific ap ttern of condition index variation that differs from the closely related non-declining long-tailed finch.

  • The Status of Estrildid Finches in North-Western Australia
    VOL. 19 (5) MARCH2002 147 AUSTRALIAN BIRD WATCHER 2002, 19, 147-160 The Status of Estrildid Finches in North-western Australia ANDREW C. BIRCHENOUGH, GARETH W. DOUGLAS and S1EWART M. EVANS Dove Marine Laboratory (Department of Marine Sciences and Coastal Management, Newcastle University), Cullercoats, Tyne and Wear NE30 4PZ, U.K. Summary There is concern that populations of some estrildid finches have declined in northern Australia. The object of the present study was to investi8ate the current status of estrildid species in the Kimberley region. This was done by countmg numbers of finches drinking at waterholes in 1996, 1997 and 1999. Additional counts were made during timed walks in areas adjacent to 10 waterholes and in the Ord River Irrigation Area in 1999. Three species of grass­ finch (Double-barred Finch Taeniopygia bichenovii, Long-tailed Finch Poephila acuticauda, and Masked Finch P. personata) were abundant and widely distributed throughout the study area but other estrildids were seen less frequently. Nevertheless, the Gouldian Finch Erythrura gouldiae was observed at sites in eastern, central and northern parts of the study area, sometimes in large flocks (50 to > 100 individuals). The Star Finch Neochmia ruficauda was recorded at relatively few sites but was abundant at places in the eastern Kimberley, including the Irrigation Area. 1Wo other species, the Yellow-rumped Mannikin Lonchura flaviprymna and the Chestnut­ breasted Mannikin L. castaneothorax, were present in large numbers in the Irrigation Area but were not recorded elsewhere. The Pictorella Mannikin Heteromunia pectoralis was recorded in large numbers drinking at one waterhole site in 1996 and at two sites in 1997 but was sighted infrequently in 1999.

We developed a test for detecting the endangered Gouldian finch Erythrura gouldiae, a small bird endemic to northern Australia. Only 1 previous study has reported an environmental DNA (eDNA) test that unequivocally identifies a bird species using the water bodies from which they drink. In controlled aviary trials with a pair of Gouldian finches, first detection in 200 ml of water occurred after as lit- tle as 6 h, but the detection rate was higher at 30 h. DNA persisted in water exposed to the sun for <12 h and in the shade for 12 h. In trials with 55 finches, persistence was up to 144 h. The eDNA test for finches and the Gouldian finch-specific test were positive for waterholes where Gouldian and other finch species were observed each morning over 3 d. Importantly, where no Gouldian finches were observed for up to 72 h prior to water sampling, the Gouldian test was negative.

Panopio Haribon Foundation, Quezon City, Philippines Carl H. Oliveros University of Kansas Biodiversity Institute and Department of Ecology and Evolutionary Biology, Lawrence, KS, USA INTRODUCTION THE GREEN-FACED PARROT Finch Erythrura viridifacies is a poorly known member of the Family Estrildidae endemic to the Philippines. Of the 10 to 13 currently recognized parrot finches (Erythrura), two other species occur within the Philippines: the widely-distributed Tawny-breasted Parrot Finch Erythrura hyperythra and the Mindanao endemic Red-eared Parrot Finch Erythrura coloria. The Green-faced Parrot Finch has been recorded from multiple locations on Luzon, two locations on Negros, and one location each on Panay and Cebu (Collar, Mallari, & Tabaranza, 1999; Paguntalan & Jakosalem, 2008); the species has never been recorded from the relatively large island of Mindoro. As with its congeners, the Green-tailed Parrot Finch seems to be eruptive and semi-nomadic in abundance and is apparently closely tied to presence of bamboo; higher concentrations are reported when January to March 2015 ~ Volume 56 No. 1 Silliman Journal 168 DISTRIBUTION AND EARLY BREEDING OF GREEN-FACED PARROT FINCHES bamboo is in flower (Payne, 2010). In 2013, the authors encountered the Green-faced Parrot Finch independently during three separate inventories on the island of Mindoro, which is geographically located between the other islands where the species had already been recorded.
