Reproductive success and symmetry in zebra finches
Article Abstract:
Thirty-six male and 36 female zebra finches were randomly separated into six groups of six birds each and the groups were separated into six free-flight breeding aviaries. The experiment was to probe the effect of colored leg-band arrangements on reproductive success in the captured birds. Data indicates that symmetrically banded males had higher reproductive success than cross-asymmetric and asymmetric males. This is most likely to be demonstrated through female choice and/or females investing higher levels of parental care toward offspring of symmetric-banded (attractive) males.

Parental investment, reproductive success and polygyny in the lapwing, Vanellus vanellus
Article Abstract:
Lapwings, Vanellus vanellus, have a mixed mating system. Both males and females engage in both monogyny and polygyny. The consequences of these mating system for males and females of the species are investigated in a population of lapwings in the UK. Results reveal that polygyny among males is related to the size of the territory. Polygynous males have better reproductive success than monogamous males. Among females, the reproductive success of polygynous individuals is only marginally lower than that of monogamous females.

Alternative reproductive strategies in the ruff, Philomachus pugnax: a mixed ESS?
Article Abstract:
A study was conducted to determine how the two alternative reproductive strategies of the ruff, Philomachus pugnax, are maintained in a population and to determine the mating success for each strategy. The results showed that the Satellites accomplished less copulations relative to their proportion in the population. To compensate for the low mating success on leks, Satellites may have improved reproductive life span or longevity as well as gained copulations off leks.
