Green rosellas Platycercus caledonicus nesting in artificial structures

The Green Rosella Platycercus caledonicus nests primarily in hollows of living or dead eucalypt trees. This note describes an instance of Green Rosellas nesting in a wall cavity, and reviews other instances of nesting in artificial structures by this species. The building used in this instance appears to have been used by Green Rosellas in 2009 and 50 years earlier, in 1958.
