Burrow and mate fidelity in the Little Penguin Eudyptula minorat Lion Island, New South Wales, Australia
Although both mate and nest fidelity are thought to exist in Little Penguins Eudyptula minor , few studies have statistically assessed the relationship between both types of fidelity and breeding success. Observations of the breeding biology of the Little Penguin were carried out between 1990 and 19...
