The decisions and conditions of animals often carry over to influence fitness in subsequent seasons or years. The condition, choices, and behaviors of parents may have a huge influence on offspring survival, not only when they are nutritionally dependent (i.e., pre-weaning or pre-fledgling), but also after they have reached independence but before adulthood (i.e., post-weaning or post-fledgling). Using a long-lived, iteroparou...

Birth timing is a key life‐history characteristic that influences fitness and population performance. For migratory animals, however, appropriately timing birth on one seasonal range may be constrained by events occurring during other parts of the migratory cycle. We investigated how the use of capital and income resources may facilitate flexibility in reproductive phenology of migratory mule deer in western Wyoming, USA, over...
