We observed a Killdeer (Charadrius vociferus) incubating a nest containing 1 Piping Plover (Charadrius melodus) egg and 2 Killdeer eggs at a sand and gravel mine in West Point, Nebraska. Four days later, the nest contained 1 Piping Plover egg and 4 Killdeer eggs. Two days later, the Piping Plover egg was absent, and the 4 Killdeer eggs remained in the nest. Eight days later the nest was destroyed. We speculate the nest began as a Piping Plover nest and was usurped by a Killdeer pair. To our knowledge, this is the first documentation of a nest containing eggs from both species. Received 12 October 2023. Accepted 3 March 2024.

Cuatro dias despues, el nido contenia I huevo de chorlito C. melodus y 4 de chorlito C. vociferus. Dos dias despues, el huevo de chorlito C. melodus estaba ausente y los 5 huevos de chorlito C. vociferus permanecian en el nido. Ocho dias despues el nido tue destruido. Especulamos que el nido inicio como nido de chorlito C. melodus y fue usurpado por una pareja de chorlito C vociferus. Por lo que sabemos, este es el primer caso documentado de un nido que contenia huevos de ambas especies. Palabras clave: Charran menor, minas de arena y grava, monitoreo de nidos de aves costeras, Piarte River, Stemula antillarum, usurpacion de nido., Killdeer (Charadrius vociferus) and Piping Plovers (Charadrius melodus) are 2 closely related species with similar habitat requirements, life histories, diets, and nest construction. Both species construct nests by digging shallow [...]
