For six years I lived below the woods at West Gosford where Kendall listened to bell birds that he based his poem on. I frequently heard them first thing in the morning and then throughout the day.

Bellbirds by Henry Kendall is one of Australia's best loved poems, and almost every Australian has at one time or another heard or repeated its melodic phrases, so evocative of the cool, dim blue and green of the Australian mountain country. This poem was first published in a work entitled "Leaves from Australian Forests" by Henry Kendall in the year of 1869.
The Bellbird itself is a very small greyish bird. Its call or melody is simply one singular chiming note which seems to ring through their environmental habitat - the mountains and the hills of Eastern Australia. They may be heard clearly in the quietness of the mountains and hills, although are rarely seen, unless an attitude of patience is adopted.
It is clear that to Henry Kendall, the mountains were a place of refuge and beauty. The Australian mountains are concentrated in a reasonable narrow band known as the "Great Dividing Range" which runs from the tip of Cape York in the north, down the eastern coast - over 3000 kilometres - through the Snowy Mountain region and all the way to the Dandenong Mountain Range in Victoria, and no doubt the same range extends under the Bass Straight and down into the wilderness areas of Tasmania.
