【明報專訊】Want to laugh your heart out? Then the kookaburra (笑翠鳥) is a bird that you should definitely meet, or rather: hear. This curious bird, found in the woods of Australia, makes a crackling sound that is almost human-like: ''hee hee hee... ha ha!... HA HA HA!!'' For this fun reason, the kookaburra is more commonly called the laughing kookaburra.
