Animals have personalities too—and some animal couples raise their young better based on how well their personalities match.
Greylag geese, which mate in long-term monogamous relationships, have better success hatching chicks if their personalities are a good match, according to a new paper in the journal Animal Behavior.
This matching of partner personalities allows the pair to coordinate more successfully when incubating their eggs, leading to increased thermal stability and protection from predators.
