Is my White's underweight?

[Cristen]

From what I've read, it's hard to distinguish. I always find statements like, "The females are slightly larger," "The males have a slightly darker throat," and "During breeding, the male may have brown pads on his feet." And I believe both male and female can croak, though the male will do it anytime and the female will do it as an answer, and that can make it hard to distinguish.

I do not know what I have.

K, well thanks anyway
