You are close. I named them all after volcanoes. I tried, where possible, to name them after volcanoes in, or near, their home ranges. However, Vesuvius and Tambora, were just too good to pass up.
If I ever get any females, my list of names are Caldera, Kilauea, Mauna Loa, St. Helen, and Etna. I just wanted to be different...
