Bubbling Yellow-vented Bulbuls Make Koh Chang Delighful
If you happened to be occupying a room facing the gardens or mountains in any of the hotels or resorts at Koh Chang, you cannot miss in all probability the sight of yellow-vented bulbul birds. This kind of bird species is a common resident in the island. It is not difficult to find its kind. They are almost everywhere. They are bolder birds which are not easily frightened by people or other birds. They are delightful to watch and observe while enjoying the natural and beautiful scenes of the surroundings of Koh Chang.
Yellow-vented bulbul, scientifically known as Pycnonotus goiavier, is a member of the buibul family of passerine birds. It is not easy to differentiate the male from female because they almost look the same. The only sure way to distinguish female from male is during nesting. They make cup-liked nests in dense bushes or trees usually 3-5 feet off the ground. They make the mangrove areas along the southernmost portion of Koh Chang their frequent habitation. Going around this area by kayak, you can hear them make a variety of musical “chup-chup-chup” calls and see their nests hanging on the branches. In terms of food, they are naturally generalist. They have a large and very wide diet. They survive on fruits, insects, carrion, flower’s nectar and invertebrates such as grasshoppers, butterflies, spider and worms.
The yellow-vented bulbul is approximately 6-8 inches long. When viewed from behind, it looks very non-descript and can be mistaken as like other bird species. The back of its head, throat and tail are colored olive brown. The distinguishing features or field marks of the yellow-vented bulbul are the black stripe on the top of its head, broad white eyebrow, black mask-like rings around its eyes, white breast and belly, and yellow tone below the belly which is right before the tail. The yellow vent is what gives the bird its name.
