Common Iora feeding on grub

posted in: Feeding-invertebrates | 1

“On 26th February 2018, I observed a male Common Iora (Aegithina tiphia) feeding in a tree at Tampines Eco Green. The branches had several rufous-coloured, triangular protrusions on them. The bird plucked one of the protrusions, grasped it with its left claw, turned it upside down to extract a grub with its beak (below).

“The photo below shows the bird successfully extracting the grub with its beak. In this picture, it also shows clearly the base of the protrusion which is shaped like a flower with 4 petals.
