There has been a considerable focus on behavioural flexibility and innovative exploitation of novel anthropogenic food resources in avian synurbanization, but the possible influence of preadaptation has received less attention. Interspecific interference competition may be a significant influence on synurbanization, but its influence has also not been very widely examined. Accordingly, we studied Galahs Eolophus […]

We monitored nests of the Pink Robin Petroica rodinogaster, Flame Robin P. phoenicia, Grey Fantail Rhipidura fuliginosa, Tasmanian Thornbill Acanthiza ewingii and Brown Thornbill A. pusilla in Tasmania to […]
