Rain probably kills more ruffed grouse than any other thing. During the first few days of a newly hatched chick’s life, a soaking rain is a killer. If the temperature is cold things get really bleak.
It is now late June and looking at my notes, at this time last year people were seeing clutches of grouse. Today it is pouring and the rain will last into the night. It is easy to imagine a hen grouse desperately trying to keep her young chicks dry.
Mother Nature can be cruel and the grouse have been through this before. The specie will survive with the strongest living on. What this rain does to the grouse population we may not know until the fall.
