The yellow chat (''Epthianura crocea'') is a small passerine bird endemic to Australia.〔Houston, W., Porter, G., O’Neill, P., and Elder, R. (2004). The ecology of the critically endangered yellow chat Epthianura crocea macgregori on Curtis Island. The Sunbird 34: 10-24.〕 They are known for their remarkable adaptions that aid their survival in their arid habitat.〔Williams, C.K. and Main, A. R. (1976). Ecology of Australian Chats (Epthianura Gould): seasonal movements, metabolism and evaporative water loss. Australian Journal of Zoology 24: 397-416.〕 ==Taxonomy== The yellow chat is a Passeriform in the Meliphagidae family.〔Christidis, L., Schodde, R., and Robinson, N. A. (1993). Affinities of the Aberrant Australo-Papuan Honeyeaters, Toxorhamphus, Oedistoma, Timeliopsis and Epthianura-Protein Evidence. Australian Journal of Zoology 41(5): 423-432.〕 They were formally considered a separate family (Epthianuridae) until the discovery of their brush tongue〔Christidis, L., Schodde, R., and Robinson, N. A. (1993). Affinities of the Aberrant Australo-Papuan Honeyeaters, Toxorhamphus, Oedistoma, Timeliopsis and Epthianura-Protein Evidence. Australian Journal of Zoology 41(5): 423-432.〕 and results from a DNA analysis led to their classification as honeyeaters in the Meliphagidae family.〔Houston, W. (2011) Distribution, breeding ecology, population and habitat use of the critically endangered Capricorn Yellow Chat Epthianura crocea macgregori Keast (Aves: Meliphagidae). Doctoral dissertation, Centre for Environmental Management, Central Queensland University.〕 They are one of four species in the ''Epthianura'' genus, with the other three being the crimson chat (''Epthianura tricolor''), the orange chat (''Epthianura aurifrons'') and the white-fronted chat (''Epthianura albifrons'').〔Christidis, L. and Boles, W. E. (2008). Systematics and taxonomy of Australian birds. CSIRO Publishing, Collingwood, Australia〕 Four subspecies of ''Epthianura crocea'' were initially identified,〔Keast, A. (1958). The relationship between seasonal movements and the development of geographic variation in the Australian Chats, (Epthianura Gould and Ashbyia North (Passeres: Muscicapidae, Malurinae)). Australian Journal of Zoology 6: 53-68.〕 however only three are currently recognised. These subspecies are primarily distinguished by their morphological variances in the adult males breeding plumages.〔Houston, W.
