- 摘要：
- to the cognitive demands of reproduction (e.g. nest construction and parental care). The results also provide evidence to suggest that breeding-related change

Data from: Are blue eggs a sexually selected signal of female collared flycatchers? A cross-fostering experiment
- 负责人：
- DOI：
- doi:10.5061/dryad.2016
- 摘要：
- as male parental effort parameters (feeding frequencies to nestlings and intensity of nest defence) were unrelated to egg colour. We discuss possible reasons

- 摘要：
- In avian cooperative breeding systems, many benefits obtained by social pairs from the presence of helpers have been uncovered. However, unt
