Recognition of family-specific calls in stripe-backed wrens

Article Abstract:

The male stripe-backed wren, Camphylorhynchus nuchalis, learns repertoires of stereotyped calls, known as WAY calls, from older male relatives. Such vocalizations are usually specific to patrilineal family groups. Playback experiments were used to determine whether the species can recognize the calls of different family groups. They were found to discriminate between the calls of unrelated neighbouring groups and unfamiliar groups, although they did not distinguish calls of males in other groups from calls of their own groups, when the males were from the same patriline.

Nest building signals male condition rather than age in wrens

Article Abstract:

The effects of male morphology and age on variations in nest-building performance were analyzed in Troglodytes troglodytes wrens. Analysis of the nest-building in male Troglodytes troglodytes indicated the correlation between nest-building and age. Habitat structure and body weight also influenced the number of nests that was built in a single season. However, there was no significant age effect in the nest-building performance of male wrens.

Sex manipulation within broods of house wrens? A second look

Article Abstract:

The association between offspring sex and position in the laying sequence in Albrecht's Wyoming population of house wrens, Troglodytes aedon, were re-examined. No sex bias among offspring from last-laid eggs in any year and overall, 42 of 86 individuals were female and also, found no sex bias among offspring from second-to-last eggs, which also hatch late, or among offspring from the first two eggs.
