Conclusion
The correction clarifies that prenatal corticosterone treatment affects mitochondrial metabolism efficiency in chicks, but overall growth and fledging success remain unaffected.
Supporting Evidence
- Chicks from corticosterone-injected eggs had a lower mitochondrial metabolism efficiency at 14 days post-hatching.
- At 7 days old, there were no significant differences in mitochondrial metabolism efficiency between treatment groups.
- Overall growth patterns and fledging success were not significantly different between the corticosterone and control groups.
Takeaway
This study found that giving certain hormones to bird eggs can change how well the baby birds use energy, but it doesn't change how big they grow or if they can fly away.
Methodology
The study involved comparing mitochondrial metabolism efficiency in chicks from corticosterone-injected eggs versus control eggs at different ages.
Limitations
The errors in the original publication did not significantly impact the overall conclusions.
Participant Demographics
Wild great tits, with specific focus on chicks from corticosterone-injected and non-injected eggs.
