Population justification: The population size of this species has not been quantified, but it is described as scarce and local.

Trend justification: The trend direction for the population is difficult to determine as there are potentially both positive and negative processes acting on the species (del Hoyo et al. 2004). There have been reported declines in range from Atlas data (Peacock 2015, Lee et al. 2017), but this may largely due to incomplete sampling, and so if there is any decline, it is probably far less severe than found (Peacock 2015).
