CICONIIFORMES: Ardeidae
Ixobrychus minutus
We spent six and a half hours at Karkarook Park watching for, and luckily, actually watching for a small part of it, this small but beautiful bittern.
Thanks go to James Mustafa who initially found this bird at Karkarook and, despite the date being April 1st, reported it on Birdline, and also to those who have added to the information on Birdline since.
