Resumen

Observamos un Rayador (Rynchops niger) el 23 de marzo de 2026, en Ushuaia, Tierra del Fuego, Argentina. Probablemente, el mismo individuo fue observado y fotografiado por numerosos observadores desde fines de febrero hasta al menos principios de abril, con un probable último avistamiento a fines de mayo, casi tres meses después de su primer registro. Esclarecer los patrones de movimiento a nivel de subespecie mejoraría nuestra comprensión de los movimientos de la especie en Argentina.
