Chestnut-breasted Quail-thrushes inhabit stony mulga country in western Queensland and N.S.W., often in quite dense mulga scrub. Further inland where these scrubs give way to more open, shrubby country you will find Cinnamon Quail-thrushes instead. The two species are very closely related; there are even a few examples of intermediate forms from the zones of overlap and their songs would be very interesting indeed. Nevertheless, Chestnut-breasteds have the more varied repertoire and to me, their songs are more noticeable than those of the Cinnamon which are simpler and seem a bit softer, but this may be a result of the more open environments where they live. Samples 438-01 -02 and -03 are three song variations, all from the same male at Yowah, Queensland. 438-01 and -02 could easily be mistaken for a distant Pied Butcherbird and 438-03 is quite like the song of a Red-browed Pardalote, but these are normal songs, not mimicy. 438-04 includes two song variations from a bird in the Grey Range, western Queensland. There is also a bit of sibilant "seeeet" calling (possibly from a mate?) and both an Horsfield's Bronze-cuckoo and Crested Bellbird are in the background. 438-05 is also from the Grey Range ( W of Eromanga); these high-pitched sibilant calls are what I term "close contact calls" and are usually given when two or more birds are foraging near one another.
