Amphibians
Hyperolius montanus (Angel, 1924)
EOL Text
A medium to rather large Hyperolius (males 25-28 mm) from the Kenyan highlands with very variable pattern. Dorsum uniformly greyish brown to light brown, yellow or greenish. A dark brown canthal stripe continues behind the eye to shoulder or groin. Throat of males yellow to white, green in green-backed specimens. Ventrum whitish, feet whitish to yellowish. Pupil horizontal.
The known samples of this species show much variation in pattern, so much so that it is hard to believe they all belong to the same species. Richards and Schiøtz (1977) have been able to separate one cryptic species from the complex as H. cystocandicans.

This species is endemic to the Kenya Highlands. It is known with certainty from several localities to the east of the Rift Valley. Specimens from Timbilil, Mau Forest Complex, might be this species, however further taxonomic work is needed. The specimens are included in this assessment until this taxonomic work is done (P.K. Malonza and V. Wasonga pers. comm. June 2012). It is a montane species occurring up to 3,100 m asl, and probably as low as 1,800 m asl. The estimated extent of occurrence is approximately 15,000 km2 (the range was used as a proxy to calculate extent of occurrence).

Found in montane grasslands and farmland in the highlands around Mt. Kenya; probably also in Mau Forest west of Rift Valley.

The call is a succession of screams. The single screams have a long duration (0.05-0.08 sec) and a well-defined frequency-intensity maximum at 2500-3000 cps.
