Table 1 Summary of the zoo-bred regent honeyeater song tutoring experimental design under an adaptive management framework showing cohorts of juveniles, their tutoring treatment, site, aviary type and cohort size. Breeding site TWPZ refers to Taronga Western plains Zoo, Dubbo; TZ refers to Taronga Zoo, Sydney. Zoo-bred birds in the tutor origin column refer to zoo-bred males that successfully learned the typical blue mountains song in previous years of the study. See Fig. S1 for description of aviary types.
