Mt Kasigau is an isolated, steep-sided mountain rising abruptly from the plains approximately 50 km south-east of the main Taita Hills massif (see IBA 21). Above about 1250 the summit is covered with cloud forest.
Kasigau has not adequadely been surveyed until relatively recently. An expedition in 1998 (Barnes et al. 1998, Pilgrim, in press) recorded good numbers of the threatened Taita White-eye but not the other Taita Hills endemic taxa (Taita Thrush and Taita Apalis). The cliffs appear to be important for nesting raptors. The Taita White-eye is considered as a (globally threatened and restricted-range) species by Collar et al. (1994), but as a sub species of Montane White-eye by OS-c (1996) and Zimmerman et al. (1996). The status of this taxon is uncertain and the results of genetic analysis are awaited. The Taita White-eye is listed as Critically Endagered, but it appears to be relaively adapdable and numerous both on the Taita Hills and Mt Kasigau. an ecological study is ongoing (R. Mulwa, in litt.), and it is possible that the species' threat status may be down-graded.
Non-bird biodiversity: The tree Memecylon greenwayi is endemic to Mt Kasigau. The Taita Hills endemic Psychotria taitensis is found here, and probably other Taita Hills specialities also occur.
