Range Description

Sitta magna is endemic to the mountains of south-western China, central and eastern Myanmar and north-western Thailand. The majority of records are from Yunnan (China), with only two known localities in Myanmar, both of which are thought to have lost the species in the last 20 years, and nine known localities in Thailand, at which it is declining. Recent comprehensive surveys in Myanmar's Shan states have been unsuccessful in locating the species (T. Htin Hla in litt. 2012). Speculative searches in Xaignabouli province, Laos, have also been unsuccessful at locating the species or much suitable habitat (J. W. Duckworth in litt. 2013). Recent surveys in Yunnan found the species to be present at low densities in most areas of mature pine forest visited (Anon. 2007), with no sign of any population increase (Lianxian Han in litt. 2013). Fieldwork in Yunnan has led to an estimate of 800-2,000 mature individuals for the province (Han Lianxian in litt. 2013), suggesting that the global population falls in the band for 1,000-2,499 mature individuals. Overall, the population is likely to be declining and becoming increasingly fragmented.
