Chestnut-breasted Mannikins are found in the north and the east coast of Australia. They are often seen in the Northern Rivers New South Wales region; in the grasses around coastal wetlands as well as more inland grasslands or rushes near to water.
The adult Chestnut-breasted Mannikin sports a very distinctive plumage with a chestnut bib underlined in black.
Younger birds are plainer although the bird on the right is showing the black line that will underline its chestnut breast.
