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. -
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. Zoo: softbill, feline diet, capelin, mealworms and insectivore diet Special Adaptations: Spur- Conservation: winged lapwings have a unique Spur-winged lapwings are abundant in their range in Africa and as such call that acts as an alert when are listed as Least Concern by IUCN. -

Stilt 50 Final 16-04-07
Stilt 50 ( 2006 ): 215-223 Are we neglecting non-migratory shorebirds? ARE WE NEGLECTING THE NON-MIGRATORY SHOREBIRDS OF THE EAST ASIAN– AUSTRALASIAN FLYWAY? MICHAEL A WESTON Birds Australia National Office, 415 Riversdale Rd, Hawthorn East, 3123, Australia (from February 2007: Green Building, 60 Leicester St, Carlton 3053, Australia) A recurrent debate within the Australasian Wader Study Group (AWSG) is whether resident (non-migratory) shorebirds are being neglected in favour of migratory species in terms of research and conservation efforts. This paper examines whether migrants have attracted a disproportionate research and conservation effort from the AWSG, by using articles published in Stilt as an index of effort. More articles (223 cf. 110) and more pages (912 cf. 267) have been dedicated specifically to migrants. Articles on migrants (4.3 ± 2.2 [mean ± standard deviation] pages) were longer than those on residents (2.5 ± 1.8 pages). These differences might reflect the fact that there are more migrants in the East Asian–Australasian Flyway since the ratio of migrant to resident species is 1.4:1 or 2:1 depending on which species are considered to use the flyway. Even when corrections are applied for this imbalance (for the 1.4:1 ratio only), a disproportionate number of pages and articles have still been devoted to migrants. Overall, it appears that there is a bias towards research and conservation effort on migratory species, with the cumulative magnitude of the bias to date equating to the number of pages in 3.8 average-length editions of Stilt . I speculate on some of the causes of the apparent bias. -

Antipredator Behavior and Breeding Success in Greater Golden-Plover and Eurasian Dotterel’
The Condor89:40-47 0 The Cooper Ornithological Society 1987 ANTIPREDATOR BEHAVIOR AND BREEDING SUCCESS IN GREATER GOLDEN-PLOVER AND EURASIAN DOTTEREL’ INGVAR BYRKTEDAL Museum of Zoology, Universityof Bergen,N-5000 Bergen,Norway Abstract. Breeding successand antipredator behavior of Greater Golden-Plovers (Plu- vialis apricaria) and Eurasian Dotterels (Charadrius morinellus) were studied in Norway over seven summers in an area 1,200 to 1,350 m altitude. Behavior was recorded in a standardizedmanner on nest inspections,on approachingparent birds with chicks, and by observing reactions to overflying predators on scheduled observation bouts. Red foxes (Vulpes v&es), Common Ravens (Corvuscorax), and Mew Gulls (Larus canus) were the most important nest and chick predators in the area. Nest predation was calculated from exposure time. During incubation both species either sneaked away from the nest when approached by a human (golden-plovers at a much larger distance than dotterels) or sat tightly and flushed at a short distancegiving distraction display. “Sneaking” had a positive effect on nest survival, and ground distraction displays had a better effect on nest survival than flight distraction displays. After hatching, golden-plover parents exposed themselves to an approachinghuman at several hundred meters distance by loud alarm calls and by encounteringthe intruder, whereasdotterels kept unobtrusive until approachedto about 40 m, and upon further approach finally gave distraction displays on the ground. Avian pred- ators at a longer distance (~300 m) from nest or chicks at most arousedalertness, while at close quarters (~50 m) they induced golden-plovers to squat flat, while dotterels exposed themselves by “tail-flagging.” Nest loss was greater for golden-plovers (78%) than for dot- terels (47%), while chick loss was greater for dotterels (65%) than for golden-plovers(28%).
