“…The nearest breeding records to the north are on islands in the southern Caribbean off Venezuela (Phelps & Phelps Jr., 1958) although the species is also regular off Suriname all year round, perhaps also suggesting local breeding (Spaans, 1978b). It is unclear whether our observations reflect local breeding or boreal migrants given historic recoveries of banded, North American birds from Pará (Mestre et al, 2010), but it seems unlikely that adults of Northern Hemisphere populations would be present in May-June (Carlos & Fedrizzi, 2013). Rodrigues et al (2010) did not provide any information on the biometrics and plumage variation of the Maranhão breeding population, which should be the subject of future taxonomic study to evaluate its uniqueness.…”

We report on the poorly-known, coastal avifauna of the Salgado Paraense (in the state of Pará, Brazil) east of the delta of the Amazonas river, combining data from recent surveys with an analysis of historical records. Three-hundred and twenty three species were recorded in the habitats inventoried: estuarine, beach and mangrove habitats, restinga, seasonally-flooded grasslands and secondary forest. Particularly noteworthy records included: the discovery of a disjunct population of Laterallus jamaicensis; a previously unrecorded staging ground for Stercorarius spp.; the second documented Brazilian record of Calidris pugnax; the first documented records in Pará for a number of marine species, including the regionally-threatened Sterna dougallii, and the rediscovery of ‘Picumnus pallidus’, a taxon of uncertain validity, all documented by archived digital vouchers. Coastal habitats represent an important contribution to local avian species-richness in Amazonia and they are theoretically better-protected by existing conservation units than neighboring terra firme habitats, yet this region’s biodiversity remains threatened by habitat loss, hunting, and major infrastructure improvements.

“…These Caribbean, Central and South American observations of Least Terns are usually considered to be migrants or wintering birds from the relatively large North American breeding populations. Carlos and Fedrizzi (2013) reviewed literature and museum records of the species along the Brazilian coast, and concluded that seasonal variation during a year-long study of numbers at Cajuais Bank (Ceará) was consistent with what would be expected for migratory birds. However, Rodrigues et al (2010) reported discovery of a breeding colony on Curupu Island (Maranhão, Brazil), and P. C. Lima and collaborators described protection of a second Brazilian breeding colony in 2021 at the mouth of the Rio Curu (Ceará; P.C.…”

“…In this study I expand on reviews of the species' status in Brazil (Carlos and Fedrizzi 2013; Somenzari et al 2018) by synthesizing data contributed by “citizen scientists” to two important and complementary online databases, eBird and WikiAves. Additionally, I summarize available recoveries of birds banded on U.S. breeding colonies that have been obtained in the Caribbean and along the Atlantic coasts of Central and South America.…”

I describe seasonal changes in the distribution of Least Terns (Sternula antillarum) along the Atlantic and Caribbean coasts based on banding recoveries and data submitted to eBird and WikiAves. Human disturbance of nesting sites and habitat loss has caused declines in most populations, necessitating focused conservation activities. Yet little is known about where these birds occur away from their breeding colonies, or what survival threats they may face. Limited observations during the non-breeding season in the Caribbean and along the Atlantic coasts of Central and South America are typically assumed to be individuals from breeding colonies along the east and Gulf coasts of the U.S. and along the Missouri and Mississippi rivers and their tributaries. However, existence of nesting sites throughout the Caribbean, along the Atlantic coast of Central America, and along the north coast of South America indicate a more complicated distributional picture. Most of the limited band recoveries obtained south of the U.S. are of birds killed during hunting activities. Future research attention, especially including banding at South American, Central American, and Caribbean nesting sites, and efforts during October-April to locate and identify marked birds, is necessary to develop a full life cycle conservation strategy for this species.
