- DOI:
- doi:10.5061/dryad.kh550nq
- 摘要:
- ween feather quality and corticosterone levels could be dependent on energetic demands, seasonality, and unpredictable events.

- DOI:
- doi:10.5061/dryad.8h6nf
- 摘要:
- variability is probably related to a trade-off between maintaining energetic efficiency and withstanding resistance to stresses. The balance involved
