Allopreening
Definition
Allopreening is the act of one penguin preening another, typically its mate or chick, using its bill to clean and arrange feathers on hard-to-reach areas like the head and nape. The behaviour reinforces pair bonds and helps maintain feather condition. It is especially common during the early breeding season when pairs reunite after months apart at sea. Allopreening has been observed in most penguin species but is particularly frequent in yellow-eyed penguins, which form long-term monogamous pair bonds.
Related Terms
The preening gland (uropygial gland) is an oil-producing gland located at the base of a penguin's tail.
The ecstatic display is a loud, ritualised courtship behaviour in which a penguin stretches its neck upward, spreads its flippers, and produces a series of braying or trumpeting calls.
