Sex allocation patterns across cooperatively breeding birds do not support predictions of the repayment hypothesis
The repayment hypothesis predicts that reproductive females in cooperative breeding systems overproduce the helping sex. Thanks to well-documented examples of this predicted sex ratio bias, repayment has been considered an important driver of variation in sex allocation patterns. Here we test this h...
