So every night when my dumpy wakes up he/she 'ribbits' for a few minutes. I read somewhere that both male and female dumpys will call but im not sure...Im guessing it is some kind of territorial call. I also got him/her to respond with a call by playing a sound clip from youtube of other dumpys calling.
Do only males call?
on a side note, my kaloula pulchra had dug a 6 inch tunnel across his/her terrarium and "hisses" at me every time i open the lid
