The Ruffed Grouse that visit my yard have long been a staple of my observing, and so is their consistent behaviour: It is a ground-foraging bird. Even with snow, grouse find clearings under trees. In a dozen years of watching them in my yard, yesterday was only the third time I have seen a grouse in a tree. What possessed it to perch on this occasion?
