Description

provided by AmphibiaWeb articles
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 account was taken from "Treefrogs of Africa" by Arne Schiøtz with kind permission from Edition Chimaira (http://www.chimaira.de/) publishers, Frankfurt am Main.

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
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.

Hyperolius montanus

provided by wikipedia EN

Hyperolius montanus (common name: mountain reed frog or montane reed frog) is a species of frog in the family Hyperoliidae. It is endemic to Kenya and known from the Kenya Highlands.[1][3] It might represent more than one species.[4]

Description

The type series, collected from Mount Kinangop, consists of one male measuring 26 mm (1.0 in) and four females measuring 29–34 mm (1.1–1.3 in) in snout–vent length.[2] Males are reported to vary in SVL between 25 and 38 mm (0.98 and 1.50 in), making them medium to large sized among Hyperolius frogs. Colour pattern is variable. Dorsum is uniformly greyish brown to light brown, yellow, or greenish. A dark brown canthal stripe runs from behind the eye to shoulder or groin. Males have yellow to white throat, or green in green-backed specimens. Ventrum is whitish and feet are whitish to yellowish.[4]

Habitat and conservation

Hyperolius montanus is an adaptable species that lives in montane grassland and farmland, montane rainforest, and moor land at elevations of approximately 1,800–3,100 m (5,900–10,200 ft) asl. It is a common species that is locally abundant. No significant threats have been identified, although pesticides and other agro-chemicals could be a local threat.[1]
