  1. Reduce inter-specific competition for nest sites of songbirds by removing competitor species

    A paired site study of patches of remnant eucalypt woodland in Victoria, Australia (Grey et al. 1997), found a significant increase in bird abundance and species richness after reduction in the numbers of noisy miners Manorina melanocephala in two of three sites.  The differences were attributable to an influx of honeyeaters and other small insectivorous birds. In a third site, possibly as the result of the presence of understorey vegetation, there was only a small starting population of noisy miners.  The reduction in their numbers influenced the species composition but not bird abundance.
