Résumé :	Kniprath E & Stier-Kniprath S 2011: Circumstances of mate change for a second brood in the Barn Owl Tyto alba. Vogelwarte 49: 75-77Before deciding for a second brood with their previous male barn owl females obviously regularly test whether there is an alternative (better option hypothesis). They then may decide in favour or against a new partnership. Divorce-second-broods may take place very close to the first breeding site of the female (distance of about 40 m). Occasionally the new male of a divorce-second-brood follows his mate to the vicinity of her first breeding site. The active role of the female in initiating a second brood is affirmed.
