SMITH, Kew, Victoria. SUMMARY An account of the first sighting for Australia of the White­ rumped Sandpiper, Calidris fuscicollis, is given with a photograph. The bird was seen at Lake Murdeduke, Victoria, many times by various observers over a period of approximately eleven weeks. FINDING THE WHITE-RUMPED SANDPIPER While watching waders along the shoreline of the west side of Lake Murdeduke, a large, salty to brackish, open lake with no above-surface vegetation, about 125 km west of Melbourne, Vic­ toria, on November 25, 1973, with R. T . Sympson, and R. J. Swindley the latter sighted a small sandpiper that was a stranger to us all. It was feeding on a short-grassed flat near the shore and moved to the muddy edge near the waterline on being dis­ turbed by us. It then commenced to feed near two Red-necked Stints, Calidris ruficollis, and some Red-capped Dotterels, Chara­ drius alexandrinus. It was dusky in general appearance, particularly on the upper­ parts but somewhat paler below, with medium-length bill and dark legs. It was a little, but noticeably, larger than the Red­ necked Stints and its bill and legs were longer than theirs. The attenuated shape of the bird was accentuated by the wings which appeared very long and crossed at the tail with the tips slightly, but obviously, exceeding the tail length. Identification problems immediately arose and while we were considering whether or not it might be a Baird's Sandpiper, Calidris bairdii, (a species since seen by Swindley and Smith) or perhaps a Western Sandpiper, C. mauri, it flew a short distance revealing a narrow white patch across the rump and was then recognised as the White-ruinped Sandpiper, C. fu scicollis. The bird was first noticed at about 11.30 hours and after studying it for over 20 minutes with 10 x 50 binoculars at dis­ tances as close as 9 m we decided to have lunch near it, keeping it under observation at the same time until approximately 12.40 hours. Although many small waders were in the area - mainly Red-necked Stints, Sharp-tailed Sandpipers, Calidris acuminata, and Curlew Sandpipers, C. ferruginea - it mostly fed alone and away from them. · 318 SMITH Bird [ Watcher It flew short distances a few times but never completely re­ tracted its legs and sometimes, on very short flights, they hung down in a similar attitude to those of a flying crake, Porzana. The legs were apparently not injured as the bird ran and walked about actively while feeding. In fact it was a busier feeder than the other wader species with which it was associating, except perhaps the Red-capped Dotterel. It probed rapidly with its bill, full length, into soft shore mud, and mud under a few millimetres of water. The probing was, at times, so rapid that the head seemed to blur. Sometimes, apart from probing, it made a quick snatch at surface food. Once it was seen coming to the muddy edge to feed with a series of short runs and abrupt stops which were reminiscent of the actions of a small dotterel-plover type. On one occasion it flew about 90 m to rocks in shallow water, where there were several Sharp-tailed Sandpipers, and went to sleep, head over back, among them for about ten minutes. Sud­ denly it woke and flew alone straight back to its previous feeding place. FIELD DESCRIPTION Size: Between Red-necked Stint and Sharp-tailed Sandpiper, but longer-billed and longer-legged than the former, with a more drawn-out appearance. General appearance: A long slender bird tapering to a long point at the rear. Dark above and pale below with a finely streaked breast area. A medium-length bill with a fine decurve towards the tip. Upper-parts: Crown and nape mouse-grey, densely streaked darker with short fine streaks. Wing-coverts area variegated·dark and light brown with an odd scattered tinge of salmon-pink (probably an indication of moult). Primaries dark-brown. Tail dark-brown with a narrow arc of white across the rump. Supercilium long, pale­ grey (whitish). Under-parts: Chin pale-grey (whitish). Foreneck light-grey and streaked darker. Breast more boldly streaked with slightly longer and wider marks which ran thinly on to the sides and flanks. Abdomen, pale-grey (whitish). Under-tail-coverts whiter, but not clear white. Under-wing area, including axillaries, pale-grey (whitish). In flight: Upper-parts appeared all dark apart from the narrow white rump patch and a paling of the tips of the flight feathers which probably was another indication of moult or wear. There was no outstanding light wing-stripe. Bill: All dark, about half as long again as in the R ed-necked Stint and a little thicker generally, with an almost imperceptible decurve. Legs: Medium length for size of bird. Appeared all dark, but at close range, in sunlight when wet, there was a greenish-olive tinge. Eye: Dark. Call: Low, almost inaudible, single notes such as "chip" or "chit". ( Plate 51 Pho to by R . J. Swirl White-rumped Sandpiper at Lake Murdeduke. I LATER OESER VATIONS The bird was observed several times by ourselves and others until it was last seen on February 10, 1974. During that time it appeared to have undergone a complete moult to full adult non­ breeding plumage, probably from remnants (when first seen) of juvenal plumage. The upper-parts were more neatly patterned, no longer showing the variegated patchiness that we saw earlier. On the last day of observation it fed often in water up to its under­ parts, submerging its head frequently to collect focd items from below the surface. REFERENCES Bannerman, D. A. & Lodge, G.

Group nesting of the White-necked Heron, Ardea pacifica, at Forbes, N.S.W. On April 26, 1976, we made a brief stop at a roadside swamp just south of F orbes in New South Wales. I was immediately struck by the number of White-necked Herons flying about and soon saw the reason why; nesting was in full swing. I counted 20 stick nests, all containing young. Most were in standing dead gum-trees in the water and one very large tree supported 5 nests, another 2. The nests ranged in height from 7.5 m to 24 m high. There were several empty nests. The largest number of young was 4 in one nest, 5 had 3 young, 10 had 2 young, 4 had 1 young. Two rather streaked young were on the ground, so some had already fledged. In "Birds in the Australian High Country," 1969, A. H. & A. W. Reed, G. F. van Tets states on p. 70 "usually single nests are found and they do not form nesting colonies but occas'onally a number of birds will nest in groups of adjacent trees." Obviously food abundance is a factor in such nesting and it would be of interest to see whether and when colony nesting is reported in this locality. · Ellen M .

  • Studies of the Foods and Feeding Ecology of Wading Birds
    STUDIES OF THE FOODS AND FEEDING ECOLOGY OF WADING BIRDS Thesis submitted in part fulfilment of the requirements for the degree of Doctor of Philosophy of the Council for National Academic Awards .. by Malcolm E. Greenhalgh, B. A. Department of Biology Liverpool Polytechnic October 1975 s ABSTRACT In this thesis are described the populations of waders (Aves: Charadrii) occurring on the Ribble Estuary, Lancashire, special reference being made to the eleven species comprising the bulk of the shore wader population. The daily routine of these birds is described including the time spent in feeding. The feeding areas are described together with the foods taken from gut and pellet analysis and direct observation. The distributions of invertebrates, and especially those of major importance as wader food, are described as well as the factors affecting these distributions. Variations in density of prey in relation to O. D., general geography of the estuary, and time of year are included. Depth distribution and variations in prey size are outlined for the main species. Food intake was studied in the eight main waders. Daily intake through the year is described. in relation to energy requirements. Variations of feeding rates with several factors are included. All data are combined to enable calculation of the total biomasses of the main prey taken by waders in the course of a year. These are compared with total minimum annual production of the prey. Future work, including a computer study based on these and extra data, is outlined. Frontispiece a. The author counting a flock of 45,000 Knot 25 August, 1972 b.

  • Mapping Farmland Wader Distributions and Population Change to Identify Wader Priority Areas for Conservation and Management Action
    Mapping farmland wader distributions and population change to identify wader priority areas for conservation and management action Scott Newey1*, Debbie Fielding1, and Mark Wilson2 1. The James Hutton Institute, Aberdeen, AB15 8QH 2. The British Trust for Ornithology Scotland, Stirling, FK9 4NF * [email protected] Introduction Many birds have declined across Scotland and the UK as a whole (Balmer et al. 2013, Eaton et al. 2015, Foster et al. 2013, Harris et al. 2017). These include five species of farmland wader; oystercatcher, lapwing, curlew, redshank and snipe. All of these have all been listed as either red or amber species on the UK list of birds of conservation concern (Harris et al. 2017, Eaton et al. 2015). Between 1995 and 2016 both lapwing and curlew declined by more than 40% in the UK (Harris et al. 2017). The UK harbours an estimated 19-27% of the curlew’s global breeding population, and the curlew is arguably the most pressing bird conservation challenge in the UK (Brown et al. 2015). However, the causes of wader declines likely include habitat loss, alteration and homogenisation (associated strongly with agricultural intensification), and predation by generalist predators (Brown et al. 2015, van der Wal & Palmer 2008, Ainsworth et al. 2016). There has been a concerted effort to reverse wader declines through habitat management, wader sensitive farming practices and predator control, all of which are likely to benefit waders at the local scale. However, the extent and severity of wader population declines means that large scale, landscape level, collaborative actions are needed if these trends are to be halted or reversed across much of these species’ current (and former) ranges.

  • A WADER MIGRATION at TLELL, QUEEN CHARLOTTE ISLANDS, BRITISH COLUMBIA with THREE ILLUSTRATIONS by J
    230 Vol. XXXVIII A WADER MIGRATION AT TLELL, QUEEN CHARLOTTE ISLANDS, BRITISH COLUMBIA WITH THREE ILLUSTRATIONS By J. A. MUNRO While at Tlell, on the east coast of Graham Island, during the period April 29 to May 30, 1935, I had an opportunity to conduct daily observations on a wader migration. The flight probably had been under way for some days prior to my arrival, and it reached the peak shortly afterward. It terminated so far as most species were concerned on May 11, after which only Sanderlings (Crocettiu a&z) were abundant. The chief feeding ground for waders was an expanse of boulder-strewn sea- bottom interspersed with areas of clear sand or of shingle, part of which was always available except at extreme high tide when the reef was completely submerged. Some of these boulders were encrusted with barnacles, others with gastropods, chiefly Littorina scutzdata. Limpets clung to their sides and the spaces between harbored various other species of molluscs. The overturning of a stone usually dis- lodged little crabs, isopods or other small animals, and a high-water mark deposit of drifted eel-grass held still others including amphipods in abundance-in short, it was a rich feeding ground not only for waders but also for gulls, bald eagles, crows and ravens. Here on the evening of April 29, with all save several small parts of the reef covered by the rising tide, a large company of waders, chiefly Black Turnstones (Arena& mdunocepkah) , but including also Aleutian Sandpipers (Arquatella ptilocds cmesi), Western Sandpipers (Ereunetes mawi), Sanderlings, Dowitchers (Limnodrom&cs griseus) and Red-backed Sandpipers (Pelidnu dpina sakkuhz) was assembled.

    VOL. LU JULY No. 7 1959 BRITISH BIRDS WADER MIGRATION IN NORTH AMERICA AND ITS RELATION TO TRANSATLANTIC CROSSINGS By I. C. T. NISBET IT IS NOW generally accepted that the American waders which occur each autumn in western Europe have crossed the Atlantic unaided, in many (if not most) cases without stopping on the way. Yet we are far from being able to answer all the questions which are posed by these remarkable long-distance flights. Why, for example, do some species cross the Atlantic much more frequently than others? Why are a few birds recorded each year, and not many more, or many less? What factors determine the dates on which they cross? Why are most of the occurrences in the autumn? Why, despite the great advantage given to them by the prevail­ ing winds, are American waders only a little more numerous in Europe than European waders in North America? To dismiss the birds as "accidental vagrants", or to relate their occurrence to weather patterns, as have been attempted in the past, may answer some of these questions, but render the others still more acute. One fruitful approach to these problems is to compare the frequency of the various species in Europe with their abundance, migratory behaviour and ecology in North America. If the likelihood of occurrence in Europe should prove to be correlated with some particular type of migration pattern in North America this would offer an important clue as to the causes of trans­ atlantic vagrancy. In this paper some aspects of wader migration in North America will be discussed from this viewpoint.
