SURVEY FOR THE RED GOSHAWK (ER YTHROTRIORCHIS RADIA TUS) IN SOUTH EAST QUEENSLAND

摘要

Intensive surveys for the Red Goshawk (Erythrotriorchis radiatus) were undertaken in areas of suitable habitat within South East Queensland (SEQ) over 60 days between December 2013 and May 2014. Despite >470 hours of active searching, and the observation of all but one (Grey Falcon, Falco hypoleucos) of the 21 other raptor species known to occur in SEQ, no Red Goshawks were detected. Whether there has been a decline in the Red Goshawk population in SEQ is difficult to establish conclusively. However, when these results are taken in light of the decline in the number of observations being reported to WildNet between 1980 and 2014, the success of surveys of a similar intensity undertaken in SEQ previously, and the reported decline and probable loss of Red Goshawks from New South Wales, a continuing retraction of the species' southerly range appears probable. Recommendations of an expert workshop convened to discuss the implications of these results and to determine what action is required for the management of this species are outlined.
