“…The eggs of Recurvirostrids, on average measure 4.5 × 3.3 cm, in height and width, respectively (Gibson, 1920), values similar to those recorded in this study. The diameter of the eggs, considering all colonies, had an average similar to H. mexicanus, (3.1 cm) (Lunardi et al, 2015), and different considering the other study (2.8 cm) (Mendonça et al, 2019).…”

“…On average, the number of eggs per nest was four eggs, similar to H. mexicanus (Lunardi et al, 2015). However Mendonça et al (2019), reported an average of three eggs in the Apodi-Mossoró River estuary, Rio Grande do Norte. Overall, nests are composed of 3-4 eggs for the genus Himantopus (Gibson, 1920;Sick, 1997).…”

“…Considering all colonies, the average nest height was 7.4 cm. The external and internal diameters of the nests were smaller than H. mexicanus nests (Lunardi et al, 2015;Mendonça et al, 2019). As in North America (Saito, 1975;Dinsmore, 1977;Coleman, 1981;Grant, 1982), such differences can be determined by the type of habitat and materials used in the construction of nests in each area.…”

“…After identifying the colonies, weekly expeditions were carried out during September and October, which comprised the breeding period at the sites between 2018 and 2020. For each nest in the colonies were recorded: (i) type of nesting microhabitat; (ii) distance between the nest and the edge of the water body; (iii) distance from the next closest nest; (iv) types of materials used to build the nest; (v) outer and inner diameter of the nest; (vi) number, height and width of eggs (according Pinho & Marini, 2014;Mendonça et al, 2019). Egg measurements were performed with a caliper rule (accuracy of 0.01 mm) and nest measurements were made with a tape measure and ruler (accuracy of 1 mm).…”

“…In the literature, the nests of the species were previously recorded in Guarapiranga, SP, in 2007 (Schunck et al, 2016) and in Quissamã, on the northern coast of the Rio de Janeiro state (Tavares & Siciliano, 2013). Breeding records of its cogeneric species (H. mexicanus) were reported in Rio Grande do Norte (Lunardi et al, 2015;Mendonça et al, 2019) and on the northern coast of Bahia (Santos & Lima, 2004).…”

Breeding biology review of White‑backed Stilt Himantopus melanurus in Brazil and a case study in the largest restinga protected area (Aves, Charadriiformes, Recurvirostridae)

In Brazil, the White-backed Stilt Himantopus melanurus is distributed in the midwest, south and southeast but breeding information is scarce. In this study, species breeding information in the country was compiled from online platform (WikiAves, eBird) and literature. A case study describing nests and egg biometry were reported in Restinga of Jurubatiba National Park (RJNP), on the north cost of Rio de Janeiro state, as well potential threats to the species. Sampling was carried out in September and December 2018, monthly in 2019 and between January to March and September to December in 2020. Overall, 70 breeding records were compiled, between 1997 and November 2021, being 64 from WikiAves in all regions of Brazil, four records from eBird in São Paulo state (in 2021) and two records in literature (one from São Paulo state, in 2007 and one from Rio de Janeiro in 2012). In RJNP, 44 nests were identified being 34 active, with an average of 3.5 eggs per nest, and overall 118 eggs were measured. The main materials used to build the nests were the saltmarsh plant and mud. Around 60% of nests were degraded or predated. Predation was the main cause of egg loss. Successful nests (with chicks or hatching signs) represented 26% of the total nests monitored. This study reports the first information on the biometry of the species' eggs and nests, confirming the northern coast of Rio de Janeiro state as a nesting area for the species.

Many shorebirds rely on sandy beaches to breed. However, these ecosystems are rare and unstable on the Guianas coast because of sediment dynamics. Nonetheless, they host 2 shorebirds that breed in the Nearctic and the Neotropic: Wilson's Plover (Charadrius wilsonia) and Black-necked Stilt (Himantopus mexicanus). We studied their breeding biology in the Amana Nature Reserve, a Ramsar Site in French Guiana, on sandy beaches bordered by brackish lagoons during 1 breeding season. From early June to late August 2008, we located and monitored 19 Wilson's Plover and 15 Black-necked Stilt nests. Most nests were associated with bare ground. While stilts preferred to build their nests with twigs closer to lagoons, plovers did not show any preference in nest location and composition. For plovers and stilts, clutch sizes were 2–3 eggs or 3–4 eggs per nest, respectively, and the mean egg volumes were 12.1 ± 0.4 cm3and 20.6 ± 0.6 cm3, respectively. The apparent hatching success for both species was low, 11% for Wilson's Plover and 13% for Black-necked Stilt, whereas daily nest survival was high for both species. Clutch sizes, egg dimensions, and egg colorations were comparable to those described elsewhere, but the breeding season started later than at other localities for the Wilson's Plover. In French Guiana, the apparent nest success values for both species were much lower than those reported in the United States and the West Indies but seemed slightly higher than in Brazil. Human activity impacts were limited in our study area and did not explain the low nest success values found. Beach flooding at high tide was the main cause of clutch failure, followed by predation. Ironically, flooding allows the maintenance of this low, open, and debris-covered habitat used by beach-nesting shorebirds.
