- 摘要:
- e affected by food resources during the nonbreeding season. To test if Mallard resource selection was related to the abundance of resources, risks

- 摘要:
- ) is an index of productivity of the preceding breeding season. However, differences in the timing of migration between family groups and nonbreeding birds may bias age

- 摘要:
- r interactions. Accurate estimates of intrinsic male effects on competitive fertilization success are therefore problematic. We used a cross-classified nonbreeding
