I came upon a pair of Spruce Grouse on my hike up to Ethan Pond on the AT this past weekend. They are quite distinctive looking with those red eyebrows. There were sitting on a boardwalk, oblivious to my approach, and only moved into the shrubbery by the side of the trail when I got within 3 or 4 feet of them. Not the sharpest tool in the shed.
I spent some time taking close-up photos of them. It's rare to come across an animal in the White Mountains that doesn't urgently flee from you, even moose. Eventually I agitated one enough so that it flew about 10 feet up into a tree, but these birds are heavy and have to flap their wings a lot to get any lift at all. Its wings sounded like a Huey helicopter trying to take off.
Once treed, the grouse raised it's tail feathers in a threat display. Actually, I got as close as two feet away from it before it paid me much mind. It didn't make any sounds though or move much after that. I subsequently learned that the species is nick-named "fool hen" for its lack of fear of humans and that they allow humans to approach within a few feet before flying. That was certainly consistent with my experience.
When I got home, I looked up the Spruce Grouse online. They inhabit much of Canada and the northern United States, mainly in coniferous forests. There are several different varieties, but the ones with red eyebrows are found in northern New England. They are ominvorous, mainly feeding on pine and spruce needles, but they also eat insects and even invertebrates. Unfortunately. the loss of forest habitat, particularly in the Adirondack region, has caused them to be placed on the endangered list.
