Abstract
Urban exploiters and adapters are often coalesced under a term of convenience
as ‘urban tolerant’. This useful but simplistic characterisation masks a more nuanced
interplay between and within assemblages of birds that are more or less well
adapted to a range of urban habitats. I test the hypotheses that objectively-defined
urban exploiter and suburban adapter assemblages within the broad urban tolerant
grouping inMelbourne vary in their responses within the larger group to predictor
variables, and that the most explanatory predictor variables vary between the two
assemblages. A paired, partitioned analysis of exploiter and adapter preferences for
points along the urban–rural gradient was undertaken to decompose the overall
trend into diagnosable parts for each assemblage. In a similar way to that in which
time since establishment has been found to be related to high urban densities of some
bird species and biogeographic origin predictive of urban adaptation extent, habitat
origins of members of bird assemblages influence the degree to which they become
urban tolerant. Bird species that objectively classify as urban tolerant will further
classify as either exploiters or adapters according to the degree of openness of their
habitats-of-origin.
