Agonistic displays are those which are intended to confront or drive off or, alternatively, appease and avoid conflict with other individuals. Macaroni penguins, particularly those on adjacent nests, may engage in 'bill-jousting'; birds lock bills and wrestle, each trying to unseat the other, as well as batter with flippers and peck or strike its opponent's nape.

Macaroni Macaroni Macaroni (, Italian: Maccheroni) is dry pasta shaped like narrow tubes. Made with durum wheat, macaroni is commonly cut in short lengths; curved macaroni may be referred to as elbow macaroni. Some home machines can make macaroni shapes, but like most pasta, macaroni is usually made commercially by large-scale extrusion. The curved shape is created by different speeds of extrusion on opposite sides of the pasta tube as it comes out of the machine. In North America, the word "macaroni" is often used synonymously with elbow-shaped macaroni, as it is the variety most often used in macaroni and cheese
