I have just completed my birdcall for an installtion to save the Bimblebox Nature Refuge in central-west Queensland from Clive parker, 153 musicians to record their interpretation of one of the calls of the 153 bird species.

http://www.burragorang.org/bimbleboxbirds.php

we were asked to read the description and interpret the call, This is my Bird:

Black Falcon
Falco subniger
Call like that of Peregrine, but deeper, slower, ‘gaak-gaar-gaak-’, becoming a more excited ‘gak-gak-gak-’ if an intruder is near the nest tree. In sudden alarm a single ‘gaaark!’. Also gives a call quite unlike other falcons in courtship and display flights – a loud, high, sharp, scratchy ‘eeik-eeik’ every 3 to 5 sec. Morecombe

Here is my interpretation!!

it was made using a cymbal, a ratchet, a bowl of water, a thunder maker and a kalimba
