Aurelie Duhec has reported a Black-crowned Night Heron at La Passe, Silhouette on 16 July 2016. This species was unrecorded in Seychelles until 1992, when an immature was reported by Neil McCulloch and Adrian Skerrett at Victoria mudflats on 27 October 1992. Further sightings followed on Mahe, especially in the Roche Caiman area, until birds were recorded as continuously present from November 1995 onward. The first sighting on Silhouette was on 12 April 1997 and birds have probably been continuously present on the island in very small numbers since that date.
