One of the most readily recognised birds in urban areas of eastern Australia, the Common Myna is also increasingly familiar to country folk as well. Introduced from Asia to combat agricultural pests, mynas were slow to expand their range initially, but they eventually spread into rural areas, where they have thrived in paddocks and along roadsides. These days their numbers are so large that the chorus of raucous calling by thousands of birds at favoured roosting sites can be deafening, and heard from hundreds of metres away.
