Abstract: | The Yellow-tailed Black-Cockatoo Calyptorhyncus funereus (YtBC) occurs throughout south-eastern Australia west to Eyre Peninsula, with closely related taxa in south-west Western Australia. A breeding population of YtBC occurs in the forests of the Mount Lofty Ranges (MLR), with foraging groups dispersing to the Adelaide Plains. No previous attempt has been made to determine the size of the population in the MLR region. The May 2011 & 2012 surveys were initiated by Dept Environment, Water and Natural Resources to provide information on the distrbution and population of YtBC in the MLR and Adelaide region. As such it provides a benchmark to determine any future population changes in the region. |

Fauna: | A media program was initiated to encourage the public to report sightings of YtBC over the weekend of May 2011 & 2012. Observers who registered interest in contributing to the survey were sent background information and data sheets and encouraged to not only count birds but provide information on numbers of males, females and juveniles, time and direction of movements and behaviour. May was chosen for the survey because it is when birds have finished breeding and congregate into fewer and larger flocks, making counting easier. The limited survey period (ie two days) aimed to reduce the likelihood of recounting the same flock at different localities, given that flocks are capable of moving many kilometres each day. At the same time several DEWNR and contract staff searched areas by vehicle and foot where congregations had been observed previously, particularly on the Fleurieu Peninsula. These staff were also on hand (via mobile phone) to assist with counting any larger flocks reported. |
