03 Nov 2020  Tue

Palm cockatoo is also popularly known as goliath cockatoo or great black cockatoo or smoky-grey or black parrot. It is 55-60 cm long and weighs 900 to 1200 grams.

The male bird displays unique behaviour of drumming with a large stick or seed pod against a dead bough or tree which creates a loud noise that can be heard up to 100 m away. However, the reason behind the palm cockatoos drum is still a mystery. One of the possibilities can be to attract females and another possibility is to mark their territory against other males.

Their vocalizations are similar to wild parrot along with a variety of additional syllables. They have high demand in the pet market for their unusual appearance.

The 100 rupia aluminium coin shows the effigy of Garuda Pancasila. Garuda Pancasila is a national emblem of Indonesia. And the reverse of the coin depicts Palm cockatoo bird and coin value.
