Demographic processes (reproductive success, survival of young and adults, recruitment of young into the breeding population) are critical to monitoring and managing landbird populations. We discuss different techniques that have been used to monitor these demographic processes in landbird populations, focusing on constant-effort mist-netting (CEM). We assess whether CEM can provide valid measures of year-to year variation in fecundity, by comparing fledging production (determined from intensive nest-searching and –monitoring) with mist net captures of Hatching Year birds. In addition to assessing bias in capture and recapture of Wrentit adults, we consider whether estimates of adult survival obtained from mist net capture-recapture data are accurate.
