- Offspring raised with siblings often have to compete for access to limited parental resources; but in adulthood, this prior exposure to competition may be beneficial rather than costly. In Seychelles warblers, nestlings raised with competitors suffered more than those raised alone; but during adulthood, those raised with competition appeared to outperform those raised singly. These results suggest a more multifaceted link between early-life competition and lifetime performance than is currently assumed.
