Divorce in birds: a review of the hypotheses

The causes behind the divorce in monogamous birds are yet to be comprehended in spite of the study on avian mating system. Many hypotheses are put forth to understand why and when individuals may divorce but they are yet to be properly organized theoretically and empirically. There are confusions about the assumptions and predictions of the individual models due to the absence of substantial theoretical framework. Further progress in the area needs sound mathematical modelling of the hypotheses.
