Population justification: The population sizes here follow estimations made by Hodder et al. (2021), who applied densities recorded in 2-ha 20-minute surveys (2.72±SD 2.99; BirdLife Australia 2020) to three measures of AOO: the minimum is the number of 2x2 km squares with records since 1990, the best estimate is double this value to account for unsurveyed area, and the maximum is four times this. Within each 1 km2, four hectares of suitable habitat was assumed. While the actual area occupied may have been less than four hectares and densities higher than in the broader landscape, many areas with birds have undoubtedly not been surveyed. The population is therefore estimated at 68,000-272,000 mature individuals, with a best estimate of 136,000 (Hodder et al. 2021). However, the reliability of these estimates is considered low (S. Garnett in litt. 2021).
Trend justification: Although reporting rates were stable between BirdLife Australia Atlases (Barrett et al. 2002), Diamond Firetails are one of a suite of taxa considered to be declining in south-eastern Australia. Historical contractions in the range have been matched by declines around Adelaide (Paton et al. 1994) and in western New South Wales and northern Victoria (Reid 1999, Olsen et al. 2005) where reporting rates declined in parts of New South Wales that had been more intensively developed (Barrett et al. 2007). Recent trends in reporting rates across the range of the species are consistent with this: from 2000–2019, reporting rates from 2-ha 20-minute counts and 500-m area searches declined by 58% and 46%, respectively (2000–2009: 40% and 41%; 2010–2019: 35% and 7%). However, not all regional results are consistent. In the Mt Lofty Ranges, abundance in 151 2-ha plots monitored annually 2001–2016 declined by about 2% per year (see Hodder et al. 2021), equivalent to 19-20% over 10 years. In north-east New South Wales, reporting rates at 41 sites declined from 18% in 1977–1980 to 12% in 2004–2006 (Gosper and Gosper 2016) and 0% in 2020 (Hodder et al. 2021). However, there was no significant change in reporting rates from 2-ha 20-min surveys for 1999–2013 for the Brigalow Belt or South-east Mainland regions (BirdLife Australia 2015); there was a strongly significant increase of 10% p.a. in surveys during 2000–2015 at over 165 sites in southern New South Wales (Lindenmayer et al. 2018); and drought had no impact on reporting rates in central New South Wales (Ellis and Taylor 2014). Reporting rates in the Australian Capital Territory show a six-fold fluctuation, with peaks in 1987–1996 and 2006–2011 and a trough in 2000–2006 and a steady decline from 2011–2017 (Canberra Ornithologists Group 2020). Combining and evaluating these trends and analyses, Hodder et al. (2021) estimated a global rate of decline of 30-49% over the past three generations and, given no indication of stability or cessation of threats, this same rate is precautionarily suspected to occur into the future.
