Chapter 6 - Behaviour and Vocalizations of Procellariidae, Hydrobatidae and Pelecanoididae

Abstract

The chapter discusses the behavior and vocalizations of a wide variety of petrels. It begins with the discussion of the fulmars which include the giant petrels, the northern and southern fulmars, the Antarctic petrel, the cape pigeon, and the snow petrel. The visual and vocal communication patterns are similar for both species and form quite a complex repertoire but one with fewer components than those of the albatrosses. The only percussion sounds commonly heard are the bill clashes of the copulation “Tattoo.” Both species visit their colonies throughout the year and nuptial displays can be seen occasionally even in mid-winter. Some such birds appear to be paired and of breeding status, others are probably older non-breeders. The Kerguelen petrels are analyzed next, and then the Gadfly petrels. Observations on the aggression, defense, and vocal repertoire of the Gadfly petrels are shared in the chapter. The Blue petrel is then discussed along with its nuptial displays, aggression, defense, and vocal repertoire. Bulwer's and Jouanin's petrels are also discussed in the chapter. The Shearwaters, and the puffin Shearwaters, and the Storm petrels are also described along with their aerial activity, ground activity, and vocal repertoire.. The family of diving petrels is also finally observed.
