Abstract

Over a 30-night period a Common Myna Acridotheres tristis was observed attacking Common Brushtail Possums Trichosurus vulpecula and harassing a female Southern Boobook Ninox boobook near her nest. One night a Myna that had been attacking Possums was chased by the male Boobook, which appeared to be chasing it as prey. We did not observe further attacks by Mynas after this night. Common Mynas were found in the dietary analysis for this pair of Boobooks.
