Grey-headed Robin Heteromyias cinereifrons


Taxonomic note

Heteromyias albispecularis, H. armiti and H. cinereifrons (del Hoyo and Collar 2016) were previously lumped as H. albispecularis (see Christidis and Boles [1994, 2008]).

Population justification: The abundance of H. cinereifrons is calculated from the density and distribution of birds and the area of climatically suitable habitat at different altitudes in 2016 (Williams et al. 2010a).

Trend justification: There has been a decline in population size in the last three generations, as predicted by climate change modelling (Williams et al. 2003, Li et al. 2009). Annual monitoring undertaken from 2000–2016 (1,970 plots, 62 different locations, 0–1,500 m altitude) revealed a highly significant 26.6% decline in the total population over the three generations to 2016 from an estimated 840,000 to 610,000 individuals. Declines occurred at lower, mid- and higher altitudes (Williams & de la Fuente 2021). These declines are broadly consistent with a 19% decline between 2000–2007 and 2013–2019 in the proportion of weeks in which the species was recorded (from 94% to 76%) at the School for Field Studies Centre near Danbulla (740–780 m; A. Freeman and M. Craig unpublished, in Williams et al. 2021) and in reporting rates for 2-ha 20-min surveys and 500-m radius area searches from 1999–2018 that declined at a rate of 44% and 12% in three generations respectively (BirdLife Australia 2020). Combining these analyses, Williams et al. (2021) estimated a global rate of decline approaching 30% over the past three generations (13.8 years; Bird et al. 2020).
