We report on an unusual nest site of a Semipalmated Plover (Charadrius semipalmatus) at La Pérouse Bay, Manitoba, Canada. The nest was located at the base of a 41-cm-high willow (Salix spp.) in a dense willow patch surrounded by coastal mudflats. Vegetation height and percent visual obstruction at the nest site were unusually high compared to height and cover previously described for Semipalmated Plovers. The nest was successful (≥2 eggs hatched). The discovery of this unusual nest site in dense vegetation suggests that some Semipalmated Plover nests may be overlooked, emphasizing the need to conduct thorough searches even in non-traditional habitats among shorebird species that typically nest in open habitats.
