Résumé :	Context. Many conservation decisions rely on the assumption that multiple populations will respond similarly to management. However, few attempts have been made to evaluate correlated population responses to management or to identify traits that could be used to predict correlations. These assumptions are central to the use of the 'population indicator-species concept' (the idea that population trends of one species can be used as an index of trends in other species) for measuring the effects of key ecological drivers. Aims. We investigated correlations among bird population trends in a mixed podocarp-hardwood forest in New Zealand in which introduced mammalian pests are controlled. We analysed trends in the abundance of
