By J. A. KEAST. The Australian Museum, Sydney. Habitat-preference amongst the migratory Charadriiformes is an aspect of study to which little attention has been paid in Australia. That these hardy and resolute birds, which bj-annually traverse half the world, should have reached a high stage of adaptability would appear certain. It is therefore surprising to find that some species restrict themselves in their choice of feeding grounds, a differential distribution that has led to a concept of rarity in the case of some comparatively common visitors. Such is the case as regards the Grey-tailed Tattler (Tringa brevipes) in New South Wales, as has been shown by observations made during recent years. The Official Checklist of the Birds of Au.stralia (1926) gives the range of the Grey-tailed Tattler in Australia as "Northern Australia, South Queensland, and Western Australia". Actually the species was known from Sydney a quarter of a century previous to this (North, 1898), but it was not until K. A. Hindwood made frequent observations at Long Reef, a rocky promontory near -Collaroy, that the species was shown to be a regular summer inhabitant of coastal New South Wales.

This page: Great knot. Photos – Grant Griffin/DBCA Photos – Grant page: Great knot. This Greater sand plover. Cover: Shorebirds and seabirds of the Pilbara coast and islands The Pilbara coast and islands, including the Exmouth Gulf, provide important refuge for a number of shorebird and seabird species. For migratory shorebirds, sandy spits, sandbars, rocky shores, sandy beaches, salt marshes, intertidal flats and mangroves are important feeding and resting habitat during spring and summer, when the birds escape the harsh winter of their northern hemisphere breeding grounds. Seabirds, including terns and shearwaters, use the islands for nesting. For resident shorebirds, including oystercatchers and beach stone-curlews, the islands provide all the food, shelter and undisturbed nesting areas they need. What is a shorebird? Shorebirds, also known as ‘waders’, are a diverse group of birds mostly associated with wetland and coastal habitats where they wade in shallow water and feed along the shore. This group includes plovers, sandpipers, stints, curlews, knots, godwits and oystercatchers. Some shorebirds spend their entire lives in Australia (resident), while others travel long distances between their feeding and breeding grounds each year (migratory).

  • Rapid Population Decline in Migratory Shorebirds Relying on Yellow Sea Tidal Mudflats As Stopover Sites
    ARTICLE Received 12 Apr 2016 | Accepted 9 Feb 2017 | Published 13 Apr 2017 DOI: 10.1038/ncomms14895 OPEN Rapid population decline in migratory shorebirds relying on Yellow Sea tidal mudflats as stopover sites Colin E. Studds1,2,3, Bruce E. Kendall4, Nicholas J. Murray1,5, Howard B. Wilson1, Danny I. Rogers6, Robert S. Clemens1, Ken Gosbell7, Chris J. Hassell8, Rosalind Jessop9, David S. Melville10, David A. Milton11, Clive D.T. Minton7, Hugh P. Possingham1,12, Adrian C. Riegen13, Phil Straw14, Eric J. Woehler15 & Richard A. Fuller1 Migratory animals are threatened by human-induced global change. However, little is known about how stopover habitat, essential for refuelling during migration, affects the population dynamics of migratory species. Using 20 years of continent-wide citizen science data, we assess population trends of ten shorebird taxa that refuel on Yellow Sea tidal mudflats, a threatened ecosystem that has shrunk by 465% in recent decades. Seven of the taxa declined at rates of up to 8% per year. Taxa with the greatest reliance on the Yellow Sea as a stopover site showed the greatest declines, whereas those that stop primarily in other regions had slowly declining or stable populations. Decline rate was unaffected by shared evolutionary history among taxa and was not predicted by migration distance, breeding range size, non-breeding location, generation time or body size. These results suggest that changes in stopover habitat can severely limit migratory populations. 1 School of Biological Sciences, University of Queensland, St. Lucia, 4072 Queensland, Australia. 2 Department of Geography and Environmental Systems, University of Maryland, Baltimore County, Baltimore, Maryland 21250, USA.

  • The Occurrence of the Grey-Tailed Tattler in South Australia by ROY P
    100 COOPER, Grey-tailed Tattler [ Bird Watcher a male bird three years to attain adult plumage, but I cannot vouch for this statement. The flight is swift and direct and, if seen in direct sunlight, the impression gained is that of a flash of long-tailed, narrow-winged golden birds. Their peculiar high pitched call is uttered whilst the birds are in flight and immediately attracts the observer's attention to them. I do not know of any other bird call that resembles the call of the Smoker. The breeding season in Victoria commences in September and is carried through until December. T he number of white eggs in each clutch varies from four to six, . and these are deposited in a hollow in either a living or a dead tree. When the eggs are due to hatch the female sits very close and rarely leaves them uncovered. The size of each egg varies considerably. A series of twelve clutches measured in Victoria showed that they averaged 30.5 mms. x 24 mms., with the sizes ranging from 29.75-31.75 x 21.25- 25.5 mms. The incubation period is 21 days, and in most observations that I have made the male feeds the female at the nest by regurgi­ tation, mainly in the early morning before 10 a.m. and late afternoon from 4 to 6 p.m. During the rest of the day the males generally flock together in feeding parties. Like most parrots they are fond of preening themselves in the early morning, usually at the top of a tall tree.

Audubon presented by strongly supported the MBTA back in 1918 when it passed. Unfortunately, the MBTA is currently being weakened by the Andrew Trotter Department of the Interior with their re-interpretation of this landmark law that blocks the Department from holding Sea and Sage Audubon is a industries accountable for bird deaths. Audubon has been partner of the Tree Care for Birds and Other Wildlife very vocal in expressing its view that this reinterpretation is project in California, which has developed best wrong. Along with celebrating birds, we are now engaged management practices to reduce harm to birds. In this in trying to protect the very law that protects our avian life. presentation by Andy Trotter, he will discuss: the qualifications of a good tree care company, industry With partnerships, we are able to greatly broaden our audience pruning standards, why arborists recommend removing for discussing birds and conservation.
