Squawking is another common form of acoustic communication in "D. novaeguineae" that is used in a slew of different contexts. Laughing kookaburras have been noted to squawk when nesting, exhibiting submissive behavior, and when fledglings are waiting to be fed. Laughing kookaburras have a greater repertoire of calls than other kookaburra species like the Blue-winged kookaburra ("Dacelo leachii") that produces two simple types of calls: “barks” and “hiccups”. This large range of calls is highlighted through cadencing, intonation, and frequency modulations that allow more detailed information to be conveyed.
