AbstractSiamang gibbons produce long and complex duet songs. The hypothesis that duetting may act as advertisement of the presence and the status of a mated pair has repeatedly been suggested for duetting birds. If a pair bonding effect of the duet is actually attained through a partner-directed learning effort resulting in a pair-specific duet, the learning investment should be concentrated into a time period as short as possible in order to avoid competitors. Therefore, after the formation of a new pair, an increase of singing activity should be expected. In order to test this prediction, the singing activity of a pair of captive siamang before and after a partner exchange was compared. In the newly formed pair, an increase in singing activity was observed. Additional observations on a second new pair show a similar trend. In this case, both new mates remained in their familiar place so that their singing activity was unlikely to be affected by the process of establishing a new territory.

Surveys for Sandhill Cranes (Grus canadensis) were conducted near Yorkton, Saskatchewan during the summers of 1995, 1996 and 1997. Seven nesting territories were identified and habitat measurements were taken at six nests. All nests were located in the emergent deep marsh zone of open water marshes within residual stands of Hardstem Bulrush (Scirpus acutus). Seven eggs were measured in four nests. Estimated hatching dates ranged from 20 May to 9 June. Total productivity for the three years was 0.80 chick per breeding pair (12 offspring fledged by 15 pairs). Individual pair productivity was impacted by disturbance, mate change, adult mortality, and predation. Hunting mortality may also impact the population.
