This is a Small Indian Civet, unusually out during daylight, photographed at Mai Po by Sharne McMillan. She runs the research for Otters in Hong Kong, and see the link to the Facebook page - or simply look up Hong Kong Otters!
These animals are normally nocturnal so a real treat to see this one out and about. They live on the ground, nesting in holes, or under rocks, but they can climb well like the rest of their family. They are primarily insectivorous but also feed on rats, mice, birds, snakes, fruit, roots and carrion. They normally live around 8 years, and the female has four or five young at a birth.
