I can vouch for their talkative nature. My Peeper calls several times a day, and it can be deafening! Still a joy.
The best time to collect is mid to late summer. Collecting during breeding season isn't advisable since they may still breed in captivity (unless you're prepared to take care of the young), and it's very stressful on them physically since they may not eat or rest as much. It's also a matter of ethics to let them do their breeding before you decide to adopt one.
They like to have vegetation to climb on, since they do act quite a bit like Tree Frogs. Mine typically prefers vegetation about 6-8 inches high. It's nice to have a water source about mid-way to that height so they are more likely to use it. It's important to have a secure habitat, since they may try to climb out.
I feed them Drosophila fruit flies during the months were I can't collect food, but I also keep them on hand in case insects of a good size aren't that available. I feed them once a week.
