Black Noddy  |  

Anous minutus

 

Black noddies use a variety of vocalizations and visual displays to communicate with conspecifics. Young use a begging call to beg for food. Main call types are identified as “chatters,” “rattles,” and “croaks.” Black noddies do not sing and vocalizations don’t vary seasonally. Foraging flocks constantly call and calls are common when nesting and roosting. Chatters are typically used in flight and may be a contact call. Rattles are alarm calls. Croaks may be given when an intruder is detected. Black noddies also use bill clacking during visual displays.
