Asian Koel (male)

I put out food for birds and civet cats. This male Koel has now started coming. It is aggressive and usually takes food for its mate that sits nearby (only coming down to feed once in a while). It is a greedy feeder and I fear it will choke one day. It spreads its wings in a reasonably good approximation of Dracula's flapping black cloak and charges at other birds (bulbuls and babblers) with open mouth. It only seems to be afraid of crows that often drive it away.
