Sage Grouse Breeding Season

I understand they won't do any exploratory drilling on our Wyoming land during sage grouse breeding season. Does anyone know when exactly that is? I saw somewhere that it was Oct-March, but other sites tell me it's in the Spring. I'm trying to figure out when we can expect to get things moving.
