Like most conifers, the Canadian Hemlock provides excellent nesting and roosting habitat as well as cover for a variety of birds. Warblers in particular enjoy nesting is this evergreen. The seeds of the cones are eaten by many different birds and small mammals. Large Canadian Hemlocks can be climbed by small black bear cubs. In northeastern Minnesota, black bear mothers and cubs spent more than 95 percent of the time in April and May within 600 feet of either an eastern hemlock or an eastern white pine larger than 20 inches in diameter. In winter, the foliage is browsed by deer, moose and snowshoe hare.
