Brumation Opinion

[zooplan]

Fertility was not the entire question.

OK!

I have to disagree about the "any time of year" statement.

As you pointed out before, most studies are about nothern populations, wich are brumating in groups. Fall matings are fewer, but also observed for those. Summer observations are very difficult and rare.
I expect that a male would try to mate with any attractive female he meet all year long in the wild too.
@Steve: Maybe you´ll have to built a deerstand on the ranch and observe all summer long to light our minds
