Population justification: This species is considered common and widespread (Pratt et al. 1987, Butler 2012, Parrish and Sherley 2012, Pratt and Mittermeier 2016, O'Brien and Masibalavu 2017). Based on density estimates from 2016 the population is estimated to fall within the band 14,000-20,000 mature individuals, depending on the assumptions used (O'Brien and Masibalavu 2017).

Trend justification: It is suspected to have declined following the cyclones of 1990–1991 which substantially reduced forest cover, with the species subsequently becoming uncommon and difficult to find (Pratt and Mittermeier 2016). However, the species is not strictly reliant on primary forest and favours shrubby forest with many young trees; it appears to have recovered from apparent declines and is considered common and widespread (Butler 2012, Parrish and Sherley 2012, Pratt and Mittermeier 2016, O'Brien and Masibalavu 2017). Surveys conducted in 2009 suggested at least a moderate and localised recovery, with 'healthy' populations of 20-30 birds recorded and anecdotal observations of birds along roadsides and near habitation (Schuster 2010). Additionally, it was found to be common in mangroves and disturbed habitat around villages and plantations in 2005-2006. Its preference for secondary habitat and forest edge, as well as its occurrence in a variety of habitat types, suggests resilience to habitat loss and disturbance (Pratt and Mittermeier 2016, J. Pilgrim in litt. 2024). As such, although small-scale agricultural encroachment and invasive species persist within the range, these are unlikely to be driving declines. Tentatively therefore, the population trend is suspected to be stable.
