I just want to point out to you Randy that Ceratophrys do not react to the calls of other species. They rarely respond to another species in their same genus. This was most likely a coincidence only or a barometric pressure change got them worked up.

As for placing them outside. If they are in a tank it's one thing, but I have seen your photos with them in your yard and that is very ill advised. They do not have the immunities and resistances that native species have against pathogens and parasites here in the states. They will not evolve such resistances because they are not native. Now they do secrete a toxin on their skin that acts as an antibiotic, but don't think that it cannot be passed by. Their diet in captivity is not the same as it is in the wild and even their natural immunity can be compromised due to the lack of specific prey items that will add to the building blocks for the chemical composition of this toxin.

Think of Dart Frogs in captivity and how their toxin is now mild at best compared to those in the wild.
