Partnerships and mechanisms of divorce in the great skua
Article Abstract:
The dissolution of bird partnerships is attributed to either incompatibility, with both birds seeking a more compatible mate, or the desire of one bird to search for a more successful partner or territory. A new study investigates partnership composition in the North Atlantic great skua and investigates the incompatibility and better option theories. Results show that most skua divorces are prompted by female desertion, with the abandoned male having difficulty in re-pairing, It is concluded that better option theory explains the result.
