Abstract: Lay Summary The hurry-up hypothesis suggests parents should complete reproduction as soon as possible when the quantity or quality of resources declines over time. However, this would come at a cost if it leads to asynchronous hatching that reduces offspring fitness. Here, we present the first test of this hypothesis in a nonavian system. In contrast to what was predicted, we find no evidence that parents complete reproduction sooner under conditions where this would be favorable.
