“After numerous nights of monitoring the Black-crowned Night Herons (Nycticorax nycticorax) along the canal near my home, a summary of its fish prey reveals that it consumes at least seven species, all of which are adapted to estuarine/tidal conditions. Apart from the catfish and rabbitfish previously reported, other fish species include:
Green Mollies (Poecilia sphenops) (above),
Crescent Perch (Terapon jarbua) (above),
Mullet (family Mugilidae) (above),
Green Chromide (Etroplus suratensis) (above),
and Mozambique Tilapia (Oreochromis mossambicus) (above).
“Additional details on other piscivorous (fish-eating) avifauna that frequent this same stretch of canal may be found in Leong (2012). The importance of maintaining optimal water cleanliness and quality in this, and many other concretised ‘rivers’ around Singapore cannot be overemphasised.”
