Received: 11 December 2013; in revised form: 10 March 2014 / Accepted: 12 March 2014 / Published: 17 March 2014 Simple Summary: Over 32 years, the bird species assemblage in the parklands of Adelaide showed a uniform decline. Surprisingly, both introduced and native species declined, suggesting that even urban exploiters are affected by changes in the structure of cities. Climate and anthropogenic factors also cause short term changes in the species mix.
