pacific reef egrets @ cyrene reef - 09Feb2016

Cyrene Reef never ceases to amaze. Made up of three submerged reefs, one can only walk on it during particularly low tides. It lies surrounded by shipping lanes in and out of the port at the south-western edge of Singapore. Despite the busy shipping and petrochemical plants surrounding it, Cyrene Reef hosts an amazing range of marine life. With the low tides, the exposed reef and its temporary shallow pools become a feeding ground for wading and shorebirds.

These reef egrets were already on the exposed bit of the reef before we got off our boat and into the dinghy. Both the white and dark morph reef egrets were present and busy darting about looking for food. The dark morphs had smoky dark grey feathers, a white throat and a yellow bill. Both morphs were actively hunting for food in the shallows and they were very good at finding food ranging from tiny crabs, prawns and even fish.

One peculiar thing both morphs did was to partially open up their wings as if to air their underwings as they were approaching their prey. Perhaps this helped to create a shadow to encourage prey to come out from hiding. Or maybe it helps with maintaining balance during active pursuits.

There were a total of 9 egrets seen that afternoon and 3 of them were dark morphs. The remaining 6 were white morphs.
