Vocal Array

A variety of loud, harsh croaks, chuckles, and mock laughter, varied by raucous cackling, reminiscent of pigs or of squawks of domestic chicken when held by legs (8). Small chicks utter a nasal tain-tain-tain all the time (3). Tail somewhat fanned to display white tips while calling (4). The call is a short series of kek...kek...kek, or loud, nasal, drawn out nyah...nyah...nyah notes, typically ending in a fast descending ‘laughter’, “nyah...nyah...nyah...nyah... nya-ha-ha-ha-ha-hahaha”.
