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. -
The First Record of Common Ringed Plover (Charadrius Hiaticula) in British Columbia
The First Record of Common Ringed Plover (Charadrius hiaticula) in British Columbia. By Rick Toochin. Submitted: April 15, 2019. Introduction and Distribution The Common Ringed Plover (Charadrius hiaticula) is a widespread Old World shorebird species that is found breeding in the Arctic and subarctic regions from Greenland, Europe, east to Siberia (O’Brien et al. 2006). In North America, this species breeds on Baffin Island, eastern Ellesmere Island (Godfrey 1986). The Common Ringed Plover winters primarily from Western Europe, the Mediterranean Basin, throughout Africa, including Madagascar, and the Middle East (Hayman et al. 1986, O’Brien et al. 2006, Brazil 2009). There are three recognized subspecies of the Common Ringed Plover (Thies et al. 2018). Distinction between the subspecies is based on moult; with features changing clinally North to South, rather than East to West, making it impossible to draw a dividing line in Northwestern Europe (del Hoyo et al. 1996, Snow and Perrins 1998). The nominate subspecies of Common Ringed Plover is (C. h. hiaticula ) which breeds from southern Scandinavia to Great Britain, and northwestern France (Wiersma et al. 2019). This subspecies winters from Great Britain, south into Africa (del Hoyo et al. 1996, Snow and Perrins 1998). The second subspecies of the Common Ringed Plover is (C. h. tundrae) which is found breeding from northern Scandinavia, and northern Russia east to the Chukotskiy Peninsula, and is a casual breeder also in the northern Bering Sea region of Alaska on St Lawrence Island (Wiersma et al. 2019). This subspecies winters in the Caspian Sea region, and from Southwest Asia, south and east to South Africa (Wiersma et al. -

Semipalmated Plover Charadrius Semipalmatus the Semipalmated Plover Prefers Coastal Mudflats, As Might Be Predicted from Its Mud-Colored Upper- Parts
196 Plovers — Family Charadriidae Semipalmated Plover Charadrius semipalmatus The Semipalmated Plover prefers coastal mudflats, as might be predicted from its mud-colored upper- parts. Small numbers also visit sandy beaches and inland lakeshores. Like other shorebirds that breed in the far north, it spends most of its life in its winter range: the last northbound migrants and the first southbound migrants almost meet each other in June. Small numbers of nonbreeders remain year round. The Semipalmated is especially common in fall migration but common in winter as well—the number wintering in San Diego County is about 750 to 1000.

Sighting of a Caspian Plover Charadrius Asiaticus at Lake Finniss, Northern Territory
VOL.18 (2) JUNE 1999 81 AUSTRAUAN BIRD WATCHER 1999, 18, 81-86 Sighting of a Caspian Plover Charadrius asiaticus at Lake Finniss, Northern Territory by NIVEN McCRIE1 and ROGER JAENSCH2 1P.O. Box 41382, Casuarina, N.T. 0811 2Wetlands International- Oceania, G.P.O. Box 636, Canberra, A.C.T. 2601 Summary There have been several reports of Caspian Plov~rs Charadrius asiaticus from mainland Australia, but doubt has been cast over their validity. This paper reports on a sighting of the species at Lake Finniss, Northern Territory. The record has been accepted by the Birds Australia Rarities Committee (Case 218), and may constitute the first confirmed record for the Australian mainland. Separation from similar species is discussed. Introduction The Caspian Plover Charadrius asiatic us breeds on steppes and in semi-deserts scattered through central Eurasia, and winters in eastern and southern Africa (Marchant & Higgins 1993). It is rather similar in appearance to the Oriental Plover C. veredus which breeds farther east, in Mongolia, Manchuria and adjacent regions, and winters in South-East Asia and Australasia (Marchant & Higgins 1993). Normally, therefore, these species do not occur in the same areas. Several occurrences of Caspian Plovers have been documented from southern Asia, including north-western parts of India, Sri Lanka and the Maldives (Hayman & Marchant 1986), and Australia and its territories (Marchant & Higgins 1993), but, to our knowledge, there has been none from South-East Asia (King et al. 1976, White & Bruce 1986). A single specimen was collected from the Cocos Keeling Islands on 17 October 1941 (Gibson-Hill1949); a single specimen was collected at Pine Creek, N.T., on 26 September 1896 (Condon 1961); and there are two published reports from near Darwin in 1974 (McKean et al. -

Do Northern Lapwings Vanellus Vanellus and Little Ringed Plovers Charadrius Dubius Rely on Egg Crypsis During Incubation?
Folia Zool. – 55(1): 43–51 (2006) Do northern lapwings Vanellus vanellus and little ringed plovers Charadrius dubius rely on egg crypsis during incubation? Miroslav ŠÁLEK1 and Eva CEPÁKOVÁ2 1 Department of Ecology and Environment, Faculty of Forestry and Environment, Czech Agricultural University, Kamýcká 129, CZ-165 21 Praha 6, Czech Republic; e-mail: [email protected] 2 Agency for Nature Conservation and Landscape Protection, Kališnická 4–6, CZ-130 23 Praha 3, Czech Republic; e-mail: [email protected] Received 13 June 2005; Accepted 19 January 2006 A b s t r a c t . We studied the possible role of clutch crypsis in antipredator behaviour in two related species of ground-nesting waders with camouflaged eggs, the northern lapwing (Vanellus vanellus) and the little ringed plover (Charadrius dubius). We examined whether this behaviour appears regularly in both species and tested the difference in the use of this trait between the two species. The results suggest that both charadriids rely on egg crypsis as a reasonable strategy toward avian nest predators. However, the larger and more conspicuous lapwings use it less frequently than plovers, probably because they rather rely on body size and aggressiveness combined with colonial breeding. Smaller and solitary little ringed plovers tended to hide the nest location more thoroughly than lapwings, probably due to their limited ability to defend the nest actively. Instead of aggressive attacks, they use alternative behavioural elements intended to deceive predators, namely incubation-feigning. Although egg crypsis is regularly used as a passive strategy for protecting nests against predators in both species, it seems to be unprofitable as an exclusive form of nest protection. -

In particular, estimates of survivorship and reproductive success derived from annual records of uniquely marked birds inform management practices that attempt to increase population size, which is especially important for threatened and endangered taxa (e.g., Pakanen 2016). Recently, we summarized population growth (Colwell et al . 2017), lifetime reproductive success (Herman & Colwell 2015), and annual variation in sur - vivorship (Mullin et al . 2010, Colwell et al . 2013) for the Snowy Plover Charadrius nivosus . Here, we submit obser - vations of a male Snowy Plover (Fig. 1) who, at 16 years of age, continues to offer insight into the conservation challenges faced by the species. Longevity – On 26 June 2001, we banded a newly hatched Snowy Plover at Eel River Wildlife Area in Humboldt County, California, USA (Fig. 2).

Dotterel; What's in a Name?
Dotterel; What’s in a name? Wader Quest Article number 16: 19/01/2021 Rick and Elis Simpson Eurasian Dotterel © Vojtěch Kubelka SUPPORTING SHOREBIRD CONSERVATION Registered Charity (England and Wales) 1183748 © Wader Quest 2021. All rights reserved. 2 The Dotterel Charadrius morinellus; when I first heard the name as a youngster it was one of those, almost mythical, species which, as far as I could see, I had little or no chance of ever seeing. In those days even an outing to Norfolk from our house in the home counties, let alone a holiday to the Cairngorms, was still only a dream; my family could not afford a car. It was an inaccessible bird and the fact that I was unlikely to see one any time soon, added to the aura of mysticism surrounding the bird, and the wonderful name highlighted the specialness of this bird to me. I had no appreciation of why the bird was called by this unusual name, I thought it was rather quaint, cute even, but in fact, nothing could be further from the truth. Human beings have a habit of disappointing me and bursting my bubbles of naivety, especially Eurasian Dotterel © Jullian Bhalerao when it comes to birds and their conservation, and when I discovered why the Dotterel was thus named a thought occurred to me; what is it about we humans that makes us feel so damn superior to every other living thing on this planet? If an animal or bird doesn’t behave in a manner in which we can find admiration, courage, speed, agility, we end up belittling the creature; witness such expressions as dumb animals, bird brained, silly cow, filthy pig and so on.
