Twelve species of shorebirds belonging to the families Charadriidae (N = 3) and Scolopacidae (N = 9) were infected with 11 species of Skrjabinoclava and there was little overlap of parasites between these two families of birds. Most Skrjabinoclava spp. are transmitted apparently in marine staging and (or) wintering areas of their hosts, as indicated by the presence of larval stages of six species. There was no evidence that transmission occurs on the breeding grounds in freshwater habitats. Skrjabinoclava tupacincai, found predominantly in sanderlings (Calidris alba (Pallas)), is transmitted on the Pacific (Washington, California, Chile) and Atlantic coasts (New Jersey) in winter and the Gulf of Mexico (Florida and Texas) in winter and spring. Skrjabinoclava myersi was found, with a single exception, only in sanderlings, and transmission is apparently restricted to coastal Washington and California in winter. Skrjabinoclava bakeri, found predominantly in western sandpipers (Calidris mauri Cabanis), is transmitted on the Pacific coast (California) and in the Gulf of Mexico in winter. Skrjabinoclava morrisoni and Skrjabinoclava pusillae were found mainly in semipalmated sandpipers (Calidrispusilla (L.)). Both parasites are transmitted in the Gulf of Mexico in spring, but S. morrisoni is also transmitted in the Bay of Fundy in fall. Skrjabinoclava inornatae, found mainly in willets (Catoptrophorus semipalmatus (Gmelin)), is transmitted in Louisiana, Texas, and Peru in winter. Skrjabinoclava kritscheri was found only in marbled godwits (Limosafedoa (L.)), and it is suggested that infected birds collected in southern Alberta in spring acquired their infections while wintering along the Pacific coast of the United States. Skrjabinoclava hartwichi, found in black turnstones (Arenaria melanocephala (Vigors)) wintering in California and ruddy turnstones (Arenaria interpres (L.)) wintering in Peru, is transmitted along the Pacific coast of North America. Skrjabinoclava semipalmatae was found in semipalmated plovers (Charadrius semipalmatus Bonaparte) wintering in California. Skrjabinoclava wilsoniae was found in Wilson's plover (Charadrius wilsonia Ord) wintering in Texas and in a black-bellied plover (Pluvialis squatarola (L.)) migrating through southern Alberta in spring. Skrjabinoclava bartlettae was found in black-bellied plovers collected in southern Alberta in spring and Louisiana in winter.

Time Lapse Video

With the use of a time-lapse video camera and infrared lamps, we quantified diurnal and nocturnal incubation sex roles in 17 pairs of Wilson's Plovers (Charadrius wilsonia cinnamominus) breeding in northeastern Venezuela. More than 82% of nests reached the hatching stage. Between the laying of the last egg and hatching of the first one, parents devoted 83% of their time incubating. Males spent more time incubating than females. Males incubated mainly at night and females mostly during daytime. Males also spent significantly more time incubating during daytime than did females during nighttime. During incubation, females relieved males at dawn and males relieved females at dusk. By relieving each other under conditions of low light intensity, parents probably reduced nest predation. Outside the breeding season, the Wilson's Plovers forage almost exclusively during nighttime. In contrast, during the breeding season, males foraged mainly during daytime low tides, probably as a consequence of their nocturnal nest attendance. During short daytime periods, on cloudy days, incubating plovers, particularly the females, abandoned their eggs to forage.

Abstract Wilson’s Plover, Charadrius wilsonia, is widely distributed in coastal areas of the Americas. This report presents the first record of breeding in this species on Coroa do Avião Island, on the coast of Pernambuco, and in the estuary of the Cardoso and Camurupim rivers, on the coast of Piauí, in northeastern Brazil, extending the known area of reproduction of this species in this region. One breeding pair was observed on October 29th 2014 on Coroa do Avião Island, and a second pair was recorded on April 6th 2016 in the Cardoso/Camurupim estuary on the Piauí coast. Both the male and the female contributed to the incubation of the eggs. The nest on Coroa do Avião island was camouflaged by the local vegetation, but despite this, the eggs were attacked by a predator. Possible predators observed on the island included Caracara plancus and domestic cats and dogs.

Todos os anos milhares de aves limícolas e migratórias invernam ao longo da costa da América do Sul, entre setembro e abril, onde adquirem massa corpórea e realizam mudas para retornar aos sítios de reprodução. Estudos quali-quantitativos foram realizados na Área de Proteção Ambiental de Piaçabuçu, Alagoas, Brasil, através da contagem direta, objetivando o acompanhamento das flutuações sazonais da avifauna migrante. Foram registradas cinco espécies da família Charadriidae: Vanellus chilensis (Wagler, 1827); Pluvialis squatarola (Linnaeus, 1758); Charadrius semipalmatus Bonaparte, 1825; Charadrius collaris Vieillot, 1818 e Charadrius wilsonia (Ord, 1814) e cinco espécies da família Scolopacidae: Arenaria interpres (Linnaeus, 1758); Actitis macularius (Linnaeus, 1766); Catoptrophorus semipalmatus (Gmelin, 1789); Calidris pusilla (Linnaeus, 1766) e Calidris alba (Pallas, 1764). Pluvialis squatarola, Charadrius semipalmatus, Charadrius collaris, Arenaria interpres, Calidris pusilla e Calidris alba foram consideradas constantes (presentes em mais de 50% das observações). Charadrius semipalmatus e Calidris alba apresentaram os maiores índices de freqüência de ocorrência nos meses de novembro e dezembro e, março e setembro, respectivamente. A correlação de Spearman demonstra uma forte dependência na migração destas espécies. A fidelidade dessas aves a APA de Piaçabuçu observada nessa pesquisa indica ser a área um sítio de invernada, reforçando sua importância para a conservação das espécies migratórias que utilizam o local.

Despite being geographically central to the Atlantic Americas Flyway for migratory birds, the Caribbean is often overlooked or underappreciated when addressing the conservation of North American shorebirds. To our knowledge, this is the first Caribbean-wide assessment of shorebird use in the region. We analyzed 211,013 shorebird species observations in the insular Caribbean from 2010–2019, representing 78,794 eBird checklists and cumulative total of 2.1 million shorebirds of 45 species. We conclude that priority areas for shorebird conservation include Humedal Sur de Pinar del Río (Humedal Sur de Los Palacios) in Cuba, and Monte Cristi in the Dominican Republic as they each likely support more than 20,000 shorebirds annually, and they host large abundances of geographic populations for particular taxa. Specifically, the former site hosts >10% of Short-billed Dowitchers (Limnodromus griseus griseus/hendersoni), and >1% of Black-bellied Plovers (Pluvialis squatarola cynosurae) and Wilson’s Plovers (Charadrius wilsonia wilsonia), while the latter site supports large numbers of Black-necked Stilts (Himantopus mexicanus). We also identified at least 15 additional sites that likely cross the 1% population threshold for one or more shorebird taxa. These sites may qualify for special international designations such as Important Bird and Biodiversity Areas or as part of the Western Hemisphere Shorebird Reserve Network; 11 of the 17 sites we identified do not hold either of these titles. Data on subspecific or geographic distributions of three species, Snowy Plover (C. nivosus), Black-necked Stilt, and Killdeer (C. vociferous), are insufficient to reveal if the sites with the highest abundances were mostly comprised of Caribbean populations or migrants, but the limited information suggests that they also likely exceed 1% thresholds on several islands. Based on our results, we recommend more extensive systematic surveys of shorebirds in the Caribbean, including research on turnover rates and movements between islands, as well as assimilation of shorebird survey data not yet included in the eBird portal.
