Diamond Firetail

The Diamond Firetail is one of Australia's most handsomely patterned grass finches, combining soft grey upperparts and a pale grey-white head with a bold black band across the breast that extends down the flanks, where it is boldly spotted with white markings resembling scattered diamonds. A bright scarlet-red rump and matching bright red bill complete its striking appearance, with a black patch around the eye adding further contrast.

Sexes are similar, though males typically show slightly bolder markings than females. The species is generally encountered in pairs or small flocks, foraging on the ground in grassy woodland where it feeds largely on fallen seed, and it can be a wary bird, often keeping close to cover.

Once more common and widespread, the Diamond Firetail has undergone significant declines across parts of its range in southeastern Australia due to the clearing and degradation of grassy woodland habitat, and it is now considered a species of conservation concern in several regions.

Key field marks

• Grey upperparts, pale grey-white head, black eye patch
• Broad black breast band extending along the flanks
• Bold white spots on black flanks, resembling diamonds
• Bright scarlet-red rump and bill

Similar species

The Red-browed Finch is smaller and plainer, lacking the bold black breast band and white-spotted flanks, with red confined to the eyebrow, rump, and bill rather than the more extensively patterned Diamond Firetail. No other Australian finch shares the Diamond Firetail's combination of white-spotted black flanks and scarlet rump.

Habitat

Diamond Firetails favour dry, open eucalypt woodland, particularly grassy box-gum woodland, as well as farmland with scattered trees and grassy understorey.

Range

The species occurs across southeastern Australia, including inland New South Wales, Victoria, and southeastern South Australia, generally at lower to moderate elevations on the inland side of the Great Dividing Range.

Migration

Most populations are sedentary, though local movements can occur in response to food and water availability, and some populations have become increasingly fragmented as suitable woodland habitat has declined.

Behavior

Diamond Firetails are usually seen in pairs or small flocks, foraging quietly on the ground for fallen seed, and tend to be somewhat wary, retreating to cover when disturbed.

Voice

Its call is a soft, plaintive, drawn-out note, sometimes rendered as a nasal 'tee-yew', along with various contact notes given by flock members.

Feeding

It feeds mainly on the seeds of grasses and herbs found on the ground, supplemented by insects, particularly during the breeding season when extra protein is needed for chicks.

Nesting and breeding

The nest is a large, bulky, domed structure of grass with a tunnel entrance, built in a shrub, tree fork, or occasionally within the base of a raptor's nest for added protection; both parents share incubation and feeding of the young.
