Urban Exploiter

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. Furthermore, cues are generally sought in behavioural ecology and physiology for the degree to which particular bird species are predisposed to urban living. The data in this paper are focused on two assemblages characterised as urban exploiters and suburban adapters from Melbourne, Australia. This study departs from the approach taken in many others of similar kind in that urban bird assemblages that form the basis of the work were identified at the landscape scale and from direct data analyses rather than indirect inference. Further, this paper employs a paired, partitioned analysis of exploiter and adapter preferences for points along the urban-rural gradient that seeks to decompose the overall trend into diagnosable parts for each assemblage. In the present paper I test the hypotheses that the distinct urban exploiter and suburban adapter assemblages within the broad urban tolerant grouping in Melbourne vary in their responses within the larger group to predictor variables, and that the most explanatory predictor variables vary between the two assemblages. In the end, habitat-of-origin better predicts degree of adaptation amongst urban tolerant birds.

I have utilised an assemblage of 91 bird species, their urban tolerance status objectively classified, with data on bird flight initiation distance (FID), to test questions of the importance of birds’ fearfulness of humans in determining urban tolerance or intolerance in the metropolis of Melbourne, Australia. While several studies have shown that mean FID for bird species (mFID) differs between rural and urban populations of bird species, stronger predictive ability is shown by variability in FID (cvFID) in modelling urban invasiveness. I test two hypotheses. Firstly, that mFID will be shorter in urban exploiter bird species than urban adapters and avoiders. Secondly that cvFID is positively correlated with bird incidence at the landscape scale in Melbourne. Relatively weak explanatory power of cvFID found in this study suggest that environmental and behavioural factors acting in concert better explain the urban tolerance of bird species and assemblages, rather than fearfulness alone.
