thank you. i am hoping i have 2 males, as i would love to hear them chirping when they are full grown. they were OOW in July i think. Since the larger of the 2 is chirping, i am hopeful. i keep trying to figure out what is triggering it, but have not been able to, so might not be from any sounds outside the enclosure. Tomorrow i plan to get my Frog sounds cd up near the Viv to see if they respond.
