Matilda the kookaburra shows off her talents in the education center of the San Diego Zoo.
This amazing call is sometimes called a laugh (hence the name, Laughing Kookaburra) but there's nothing funny about it. Kookaburras use their trilling laugh-like calls to establish territory and home ranges. The call can travel for great distances and it lets other kookaburras know who lives in the area.
