SUMMARY
Heron, S. J. 1970. The birds of Middle Swan, Western Australia. Emu 70: 155–158.
An area at Middle Swan about 20 km east-north-east of Perth was studied regularly from February 1964 to December 1966, and all the bird species recorded. A systematic list is given with notes; those birds observed in the district, but not within the studyarea, have been added for the sake of completeness.
