The advertisement calls of a fossorial frog, Kaloula pulchra was studied during the breeding season at two study
sites of Mizoram. Sound production is primarily a reproductive function of male anurans. Advertisement calls
attract females to breeding areas and announce other males that a given territory is occupied. Commonly known
as the Banded frog, Kaloula pulchra is listed under a least concern and distributed throughout Southeast Asia,
South Asia and China.
Male mating call started from 4:00 PM and a
single male vocalization can be heard from a distance
of about 100 m away. The males first enter the breeding
site and float in the pools, and blow up their bodies to
make calls (Fig. 1). Their sounds are loud and deep
like a bull moo. Their rounded shape is exaggerated
even more when they inflate while floating and calling.
In this observation, the distance between two adjacent
calling males in the breeding ground are usually 2m-
10m apart. A single male usually occupied one rockpool,
if more than one male occupied a small rockpool,
the dominant male would drive out other males.
