Nestling detectability affects parental feeding preferences in a cavity-nesting bird
Article Abstract:
The nestlings attempt to obtain essential resources for their growth, development and survival through a series of acoustical and physical begging signals directed towards their parents. Various results suggests that, in nests with low luminosity, red mouths decreases nestling delectability to the feeding parents and supports the hypotheses that poor luminosity in nesting cavities can select for pale mouths.

An experimental study of mate guarding and paternity in house wrens
Article Abstract:
The effectiveness of mate guarding in house wrens, Troglodytes aedon, is examined by preventing males from guarding through a short-term detention during the female's fertile period. The results support the hypothesis that male guarding can effectively reduce the risk of cuckoldry, but not parental care to nestlings.
