Breeding Colonies of Least Terns (Sternula antillarum) in Northern Sonora, Mexico, 2006–2008
The Southwestern Naturalist, 2012Abstract We document distribution of breeding least terns (Sternula antillarum) in northern Sonora, Mexico, 2006–2008. We report breeding activity at six sites with active colonies, including three previously undocumented colonies.

Although nest usurpation is common in some species and orders of birds, usurpation has rarely been reported for Sterninae. We observed a Sterna hirundo (Common Tern) egg in an active Sternula antillarum (Least Tern) nest with a complete clutch in a mixed-species Sterninae colony in Chesapeake Bay, MD, in May 2018.

ABSTRACT On the Missouri River, the federally endangered interior population of Least Terns (Sternula antillarum) historically nested on sandbars created by sediment deposited during high flows. The Missouri River has been dammed and regulated, however, resulting in decreased flooding and sediment deposition and thus decreased sandbar habitat. In 2011,

Abstract Nest usurpation is a strategy in which an individual or pair of one species takes over the nest of another species. This is the first documented occurrence of a Piping Plover (Charadrius melodus) pair usurping an Interior Least Tern (Sternula antillarum athalassos) nest.

Consideration of annual population count data, stream flows, water levels, and nesting habitat availability over a 29-year period suggest that Least Terns (Sternula antillarum athalossos) nesting along the Cheyenne River and Oahe Reservoir in South Dakota, USA, select areas primarily in response to reservoir water levels early in the breeding season ...

Many bird species of conservation concern have behavioral or morphological traits that make it difficult for researchers to determine if the birds have been uniquely marked. Those traits can also increase the difficulty for researchers to decipher those markers.

Abstract Botany Bay Plantation Wildlife Management Area is one of only four known natural nesting sites for least terns ( Sternula antillarum ) on the South Carolina coast, and more than 20,000 people visit the 3-mile stretch of beach each nesting season since it opened to the public in 2008.

Abstract. Although a species of conservation concern, little is known about the reproductive success of Least Terns (Sternula antillarum) throughout the southeastern USA where availability of natural beaches for nesting is limited. Daily survival rate (DSR) of nests and chicks was examined at four natural nesting sites in Cape Romain National Wildlife ...

Abstract. Nest-habitat selection in colonial species has rarely been assessed at multiple spatial scales to evaluate its fitness consequences. Management for the federally endangered U.S. Interior population of Least Terns (Sternula antillarum) has focused on maintenance of breeding habitats, including mechanical construction of sandbars from dredged ...

Notes on the breeding status of Least Tern (<em>Sternula antillarum</em>) on St. Kitts, West Indies
Journal of Caribbean Ornithology, 2013Abstract: The breeding population of the Least Tern (Sternula antillarum) in the Caribbean is small and requires monitoring due to anthropogenic disturbances of fragile marine and terrestrial ecosystems. In 2006 and 2007, surveys were conducted of all historical colony sites on the South East Peninsula salt pond system and along beaches during the ...
