註釋Celebrating the white-tailed ptarmigan in a month-by-month photographic essay, Joyce Gellhorn reveals the elusive habits of the only bird capable of surviving on the harsh, alpine tundra of the Rocky Mountains throughout the year. Discover an appreciation and awe for the adaptations of a species living on the edge, a species that contends with bitter cold, fierce winter storms, and short breeding seasons. Because they live in a precarious balance with their environment, white-tailed ptarmigan may well serve as a barometer to the health of our planet in terms of global warming. Book jacket.
