Taxonomic note
Butorides striata (del Hoyo and Collar 2014) was previously split as B. striata and B. virescens following AOU (2003), and before then B. striata was split as B. striatus and B. sundevalli following Sibley and Monroe (1990, 1993). Gender agreement of B. striata follows David and Gosselin (2002b).
