Laughing Kookaburras often become quite tame around humans and will readily accept scraps of meat. This ‘pre-processed’ food is still beaten against a perch before swallowing.
This one of a pair has repeatedly stolen goldfish out of the water-jar in my backyard. It sits in front of me in a tree and bashes the goldfish against the branch repeatedly and then manoeuvres to get it down its throat. He also has a way of looking entirely innocent of any wrong-doing or just avoids my gaze entirely!
