It was just over two weeks ago when I noticed the first hummingbird had returned to Opal Creek. Lured here, no doubt, by the same sunshine and mild temperatures that drew many of us Oregonians outside over the Easter weekend. A day or two later, I heard the frogs calling to each other from the slowly warming muck at the pond’s edge, tucked into a still shady corner of the yard. But, just today when I woke, the frogs were silent and the hummingbirds were nowhere to be seen. In their place was a fresh layer of heavy, wet snow and cold, dark clouds raking the mountains overhead.
