Some additional notes on Movement and Longevity of the Common Myna Sturnus tristis


In August 1990 we began a small study to investigate the potential movements of the introduced Common Myna Sturnus tristis in the urban environment of Canberra. An initial report on a movement of 9.5 kilometres by an individual bird over a period of nearly three years was reported by Nicholls et al. (1996). The present short communication presents some additional movement data and reports some observations of longevity for individuals of this species including extending the longevity from that reported in Higgins et al. (2006). Over the period August 1990 to May 1996 we captured and banded a total of 55 individuals at our home in de Chair Street, Deakin, ACT. Trapping was initially undertaken using a standard mist net located in the back garden of our home. Subsequently we used a walk-in trap; approximate dimensions 1 metre by 1 metre by 1.8 metres. After the Common Mynas became competent at walking in and out of the funnel shaped entrance we tried a top drop through entry (or modified house trap, McClure 1984), which the Common Mynas also became skilled at exiting. Mist netting was conducted on at least 28 days during the period August 1990 to early 1992 and yielded a total of nine Common Mynas. From August 1992 to May 1996 the trap caught a total of 46 Common Mynas, of which two were re-traps.
