During drastic changes in barometric pressure—as a result of thunderstorms or heavy rainfall/snowfall—Wood frogs’ behavior will increase. Therefore, they will hop around excessively and sometimes ram themselves into the terrarium glass. This can result in injuries to the frog, particularly to their noses. I have observed this behavior over the past 7 years that I have kept Woodies, and thankfully none of them have hurt themselves. Other than that, Wood frogs are relatively calm in the terrarium.
