Second bittern at Denis Island

Janske van de Crommenacker and Martijn van Dinther have reported a Eurasian Bittern present at Denis Island from around 25 February to 5 March. This is the second report from Denis for the current migration season following a sighting on 3 December 2015. This December bird was the first record for Denis Island but this second bird means  Denis is suddenly the bittern capital of Seychelles, being the only island where the species has been seen more than once. There are seven other records from Aride (1988), Praslin (1993), Mahe (2000), Cousine (2003), Bird (2005), Alphonse (2010) and Frégate (2012).
