When to expect pine siskins in Idaho
Pine Siskins live in Idaho all year. Cold winters with inversions in the valleys; mountain finches and Bohemian Waxwings move into towns. That makes the cold months the time your yard matters most to them: their winter diet shifts toward spruce, birch and alder seed.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
