The Milky storks found in Sungei Buloh Wetlands Reserves are actually free ranging birds from both the Zoo and Bird Park. Why do they fly to Sungei Buloh? I guess its to feed, this shows that Sungei Buloh does have a rich mudflat full of organism in the mud.
They seems to get along well with the great egret (above) too. The Great Egret Egretta alba is a migrant with wing span of up to 215cm. This is also the largest egret found in Singapore.
It's been a while since I saw the purple heron
Ardea purpurea.
What a nice day at Sungei Buloh!
