Witu Forest Tree Frog

A rather small Leptopelis (males 31-34 mm) from the low-lying savannas in coastal Kenya and north-eastern Tanzania. Has reduced webbing and a rather constant pattern forming a dark interorbital bar and an indistinct reversed Y on dorsum. Voice a clack and scream. No pectoral glands in males.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.

Found in the rather dense savanna with high grass and many trees and bushes in the coastal lowlands of southern Somalia, Kenya and adjacent parts of Tanzania. It is the only Leptopelis found here; L. bocagii is found in the Kenya highlands, and L. flavomaculatus is confined to forests.

iMales call from widely-spaced positions in large, dense bushes or on tall grass, usually over 1.5 m above the ground. The voice is an un-melodious clack followed by two or three shrill screams, or sometimes the screams followed by the clack, or clacks or screams alone. It is difficult to believe that it is the same animal uttering the two calls. The clack has a brief duration (0.05 sec) and a very indistinct frequency-intensity maximum at 1500-2000 cps, while the scream has a longer duration (0.15-0.20 sec) and a well-defined frequency-intensity maximum at 2000 cps. The structure of the call consists of harmonics with a vibrato, with a fundamental of about 400 cps.

Leptopelis concolor is a species of frog in the family Arthroleptidae. It is found in the coastal lowlands of southern Somalia, Kenya, and northeastern Tanzania. Common names triad tree frog, Witu forest treefrog, and pale-coloured tree frog have been coined for it.

Leptopelis concolor inhabits savanna woodland and clearings in dry forest at elevations below 1,500 m (4,900 ft). It can survive in modified habitats as long as good vegetation cover remains. The eggs are laid in a nest buried in mud near water. It is a common species and, given its adaptability, it is not considered to be facing any significant threats. It is present in several protected areas, such as the Tsavo East and Tsavo West National Parks in Kenya.
