 The noisy miner has benefited from the thinning of woodland on rural properties , heavy grazing that removes the understory , fragmentation of woodland that increases the percentage of edge habitat , and urban landscaping practices that increase open eucalypt environments . It has been described as a ' reverse keystone ' species , as it is colonizing an ever @-@ increasing range of human @-@ dominated habitats , and aggressively excluding smaller bird species from urban environments . This phenomenon has been also observed in rural areas . A field study across the South West Slopes of New South Wales , showed that the noisy miner 's presence corresponded with reduced numbers of insectivorous birds such as fantails , whistlers , the restless flycatcher ( Myiagra inquieta ) , and other honeyeater species , and that this decrease was most marked in sites with better access to water and nutrients . While it has been hypothesized that the proliferation of large @-@ flowering grevillea cultivars has contributed to the abundance of noisy miners , recent research has identified the proliferation of lightly treed open areas , and the presence of eucalypt species as the most significant factors in the population increase . Large @-@ flowered grevillea hybrids such as Grevillea ' Robyn Gordon ' can benefit the noisy miner , in that an abundance of resources is usually dominated by larger aggressive honeyeaters , and a continuous nectar source could provide an advantage for the non @-@ migratory species . A field study in box @-@ ironbark country in central Victoria found miner numbers were correlated with the occurrence of yellow gum ( Eucalyptus leucoxylon ) , which reliably produces flowers ( and nectar ) each year . The abundance of the noisy miner is primarily determined by habitat structure .
