Jeremiah Looei’s two videos show the Violet Cuckoo (Chrysococcyx xanthorhynchus) feasting on caterpillars. Insects are its favourite food, especially caterpillars. The hairy ones are carefully prepared by swiping on the branch before swallowing LINK 1 and LINK 2.
According to Khew Sin Khoon of Butterfly Circle LINK, the caterpillars are most probably those of a moth. “The urticaceous hairs and the smaller caterpillar heads also strongly suggest that these are moth caterpillars,” wrote Sin Khoon. “Also, from the way the caterpillars are eating, they seem to be taking off the surface of the leaf whilst eating it, unlike most butterfly caterpillars which don’t usually do this.”
