Common Iora - Aegithina viridissima, at the Eugenia oleina tree
Malays call this bird as 'Burung Kunyit Kacat'
Zone C

Recently I noticed many Common Ioras around at the park.  Their favourite hangouts  are the Eugenia oleina and the Jackfruit trees.  At the moment the Eugeina oleina trees are flushing.  There are no fruits or flowers yet.  Thus they are dropping by the trees in search for caterpillars and ants.  They are small birds and mesh well among the leaves.  Their voice however announce their presence.  The distinctive call sounds like this ...Weeeeeeeeeee-tu .
