The Wrybill Anarhynchusfrontalis:a brief review of status,threats and work in progress.Wader Study Group Bull. 100: 20-24. The Wrybill is a threatenedplover endemic to New Zealandand unique in havinga bill curvedto the right.It is specializedfor breedingon bareshingle in thebraided riverbeds of Canterburyand Otago in the SouthIsland. After breeding,almost the entirepopulation migrates north and wintersin the harboursaround Auckland. The speciesis classifiedas Vulnerable. Based on countsof winteringflocks, the population currently appears to number4,500-5,000 individuals.However, countingproblems mean that trendsare difficult to determine. The mainthreats to theWrybill arebelieved to be predationon thebreeding grounds, degradation of breeding habitat,and floodingof nests.In a recentstudy in the MackenzieBasin, predation by introducedmammals (mainly stoats,cats and possibly ferrets) had a substantialimpact on Wrybill survivaland productivity. Prey- switchingby predatorsfollowing the introductionof rabbithaemorrhagic disease in 1997 probablyincreased predationrates on breedingwaders. A recentstudy of stoatsin the TasmanRiver showedthat 11% of stoat densexamined contained Wrybill remains.Breeding habitat is beinglost in somerivers and degraded in oth- ers,mainly by waterabstraction and flow manipulation,invasion of weeds,and human recreational use. Flood- ing causessome loss of nestsbut is alsobeneficial, keeping nesting areas weed-free. The breedingrange of the speciesappears to be contractingand fragmenting, with the bulk of the popula- tion now breedingin three large catchments. -

Spur-Winged Lapwing Vanellus Spinosus
Spur-winged Lapwing Vanellus spinosus Class: Aves Order: Charadriiformes Family: Charadriidae Characteristics: Also known as the spur-winged plover (not to be confused with the recently renamed masked lapwing of Australasia), this lapwing is a wading bird identified by their striking white cheek feathers, black head cap, brown wings against a black body and long black legs. Behavior: In Africa, lapwings don’t travel far outside their home area but merely make short movements to find wetter areas of their habitats. They spend Range & Habitat: their time searching the marshy ground for small invertebrates. Marshes and wetland habitats of central Africa Reproduction: Because of their large range, these birds have variable breeding seasons. Spur-winged lapwings nest in solitary monogamous pairs, often with other mixed species bird nesting colonies. The large nesting groups help protect the birds in the colonies against predation. The lapwing pair will build a nest in a scrape on the ground sometimes lined with vegetation. The female lays 2 eggs that are yellow with brownish black mottling. They hatch after a 28-day incubation period and both sexes help feed the young. If they double-clutch, the male tends the older chicks while the female incubates the second brood (Sacramento Zoo). Lifespan: over 15 years in Diet: captivity, up to 15 years in the Wild: Invertebrates wild.

Ecology and Conservation of Australia's Shorebirds
Ecology and Conservation of Australia’s Shorebirds Robert Scott Clemens B.S. Wildlife Biology M.S. Natural Resources A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2016 School of Biological Sciences 1 Abstract Global biodiversity continues to decline rapidly, and addressing this situation requires an understanding of both the problems and the solutions. This understanding is urgently required for animals occupying wetlands, among the most threatened of all habitats globally. In this thesis I focus on the ecology and conservation of shorebirds, a group comprising many threatened and declining species dependent on wetlands throughout much of their annual cycle. I focus on threats operating within Australia, where wetland loss and degradation continues due to human activity. Non-migratory shorebird species that travel widely across Australia’s inland wetlands have been reported as declining in eastern Australia, but a national assessment is lacking. Migratory shorebird species that visit Australia from breeding grounds overseas appear to be declining most due to factors beyond Australia’s borders, but it is not clear if threats located in Australia are exacerbating these declines. I make the most of the rich data available on shorebirds in Australia to address these knowledge gaps, in the hopes of better targeting shorebird conservation actions in Australia. In chapter one I introduce the importance of conserving migratory and highly mobile species. I then review how pulses in resource availability such as those exemplified by Australia’s ephemeral wetlands impact wildlife populations. I also provide an overview of shorebird conservation in Australia. These introductions provide the theoretical underpinning for the work presented later, and highlight the challenges inherent in understanding where and when highly mobile species such as shorebirds have been impacted. -

The Role of Habitat Variability and Interactions Around Nesting Cavities in Shaping Urban Bird Communities
The role of habitat variability and interactions around nesting cavities in shaping urban bird communities Andrew Munro Rogers BSc, MSc Photo: A. Rogers A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 School of Biological Sciences Andrew Rogers PhD Thesis Thesis Abstract Inter-specific interactions around resources, such as nesting sites, are an important factor by which invasive species impact native communities. As resource availability varies across different environments, competition for resources and invasive species impacts around those resources change. In urban environments, changes in habitat structure and the addition of introduced species has led to significant changes in species composition and abundance, but the extent to which such changes have altered competition over resources is not well understood. Australia’s cities are relatively recent, many of them located in coastal and biodiversity-rich areas, where conservation efforts have the opportunity to benefit many species. Australia hosts a very large diversity of cavity-nesting species, across multiple families of birds and mammals. Of particular interest are cavity-breeding species that have been significantly impacted by the loss of available nesting resources in large, old, hollow- bearing trees. Cavity-breeding species have also been impacted by the addition of cavity- breeding invasive species, increasing the competition for the remaining nesting sites. The results of this additional competition have not been quantified in most cavity breeding communities in Australia. Our understanding of the importance of inter-specific interactions in shaping the outcomes of urbanization and invasion remains very limited across Australian communities. This has led to significant gaps in the understanding of the drivers of inter- specific interactions and how such interactions shape resource use in highly modified environments. -
Helminth Parasite Communities in Four Species of Shorebirds (Charadriidae) on King Island, Tasmania
Papers and Proceedings of the Royal Society of Tasmania, Volume 132, 1998 49 HELMINTH PARASITE COMMUNITIES IN FOUR SPECIES OF SHOREBIRDS (CHARADRIIDAE) ON KING ISLAND, TASMANIA by Albert G. Canaris and John M. Kinsella (with six tables and three text-figures) CANARIS, A.G. & KINSELLA, J.M., 1998 (31 :xii): Helminth parasite communities in four species of shorebirds (Charadriidae) on King Island, Tasmania. Pap. Proc. R. Soc. Tasm., 132: 49-57. https://doi.org/10.26749/rstpp.132.49 ISSN 0080-4703. PO Box 717, Hamilton, Montana, USA 59840 (formerly Department of Biological Sciences, University of Texas at El Paso) (AGC); and Department of lnfectious Diseases, College of Veterinary Medicine, University of Florida, Gainesville, Florida, USA 32611 QMK). Helminth community composition and structure were examined among two resident shorebird species, red-capped plover, Charadrius ruficapillus (N = 20), and masked lapwing, Vanellusmiles (N = 5), and two migrants, ruddy turnstone, Arenaria interpres (N = 20), and curlew sandpiper, Calidrisfe rruginea (N = 5), on King Island, Tasmania in March-April 1993, prior to northward migration to the nesting grounds. The total number of species of helminths recovered was 28 and life cycles of at least 19 of these were occurring on the island. Twenty-fivespecies were categorised as generalists and three were undetermined. One to three species of helminths were dominant in each host species. Eight species, to various degrees, were common among the four species of host. Most sharing occurred in the mucosa! trematode guild. Similarities between resident Charadrius ruficapillus and migrant A. interpres was 32.7%, while the mean number of species and mean number of helminths were significantlyhigher in A.
