Always thrilled to spot the otters at Sungei Buloh. This time there were only two adults - a male and a female. These days I hardly hear the otters call to each other. Of late, most of my sightings during the weekends have been by spotting them silently moving along the river.
I believe the female is lactating as her mammary glands were engorged. She may have pups hidden in a den somewhere. After her nap, the proceeded to scent mark and then slip back into the river.
