New records. One female was walking on flooded grass- lands of the ESNR on 24 June 2016. We recorded this species in all systematic surveys since 17 July 2016.

Identification. Males with grey head and white crescent on the face and flanks. The covering feathers make blue patches. Females with mottled brown head and neck, but without half-moon.

Remarks. We recorded a female and eight chicks swimming in a wetland in the ESNR on 30 July 2016. Between 21 April and 12 June 2018, we recorded 11 active nests with an average of 11 eggs (45.5 mm × 33 mm), of which 83% of chicks hatched, a high value compared to 35% reported by Glover (1956). A boreal migratory species.
