Buff-breasted Buttonquail: an Update

A scientific report has been amended in response to criticism by some in the birding community that researchers were dismissive of multiple sight records of the extremely rare Buff-breasted Buttonquail (illustration above by Birds of the World). The report published by the Threatened Species Recovery Hub of the National Environmental Science Program last July raised the prospect of all recorded sightings of Buff-breasted Buttonquail from south of Cooktown being misidentified Painted Buttonquail. A newly amended version of the report concedes that some records may be authentic. The Buff-breasted Buttonquail is found only in the savanna woodlands of Queensland’s Cape York Peninsula (below). The July research report by a team of University of Queensland scientists says the last confirmed records of the bird were probably in the 1920s. It argues that the buttonquail population may have crashed due to several factors including the introduction of cattle, changed fire regimes and feral predators. What follows are recent changes [in square brackets] made to the report.

(1) Version 1: “These unverified observations have influenced our perception of the species’ autecology and threats….” Version 2: “These observations have influenced our perception of the species’ autecology and threats….” [unverified is dropped] (2) Version 1: “This research has found sufficient evidence to suggest that all southern records of Buff-breasted Button-quail could involve misidentified Painted Button-quail. Our research has found the features and methods researchers and birdwatchers have used to identify Buff-breasted Button-quail from Painted Button-quail are incorrect.” Version 2: “Our research has found that many of [not all] the features and methods researchers and birdwatchers have used to separate Buff-breasted Button-quail from Painted Button-quail are incorrect. This may suggest that a significant proportion of southern records of Buff-breasted Button-quail could involve misidentified Painted Button-quail.” [The suggestion that all southern records could involve misidentification is removed.] (3) Version 1: “Due to our research there is now considerable evidence to suggest all reports from this region have in fact been misidentified Painted Button-quail.” Version 2: “Due to our research there is now evidence to suggest many, and perhaps most [not all] reports from this region may have been misidentified Painted Button-quail.” (4) Version 1: “Furthermore, this project has determined previous reports from the 1980s to the present day in the Wet Tropics and Einasleigh Uplands Bioregion are likely to be erroneous, suggesting the last confirmed record of this species was probably in the early 1920s.” Version 2: “Furthermore, this project has determined that a significant proportion of reports from the 1980s to the present day in the Wet Tropics and Einasleigh Uplands Bioregion could have been misidentifications.” [“significant proportion” is added; “likely to be erroneous” is deleted] (5) Version 1: “However no contemporary reports are accompanied by verifiable evidence despite the dramatic increase in photography by the birding community.” Version 2: “However, no contemporary reports are accompanied by verifiable evidence, such as a skin or photograph, despite the dramatic increase in photography by the birding community.” [What constitutes verifiable evidence is clarified.] The edited report is here (copy and paste URL): file:///C:/Users/Greg%20Roberts/Documents/BBBQ%20version%202.pdf
