General characteristics

This Secondary Area is defined by the range of the threatened Rueck's Blue-flycatcher Cyornis ruckii (classified as Vulnerable), which is known from two specimens collected in the Indonesian province of Sumatera Utara (see map, p. 488). They were found in exploited forest at an altitude of c.150-200 m (van Marle and Voous 1988) in an area which has now largely been deforested. The species may presumably occur elsewhere in the lowlands of northern Sumatra but is likely to have been affected by the extensive lowland deforestation which has taken place there (see RePPProT 1990). The lowland rain forests on Sumatra also support several widespread threatened species (Collar et al. 1994). This Secondary Area is adjacent to Sumatra and Peninsular Malaysia (EBA 158), but the birds of that EBA occur in montane habitats at higher altitudes.
