Winter isn’t over yet, but signs of its impending end are getting stronger. It’s no longer 0 °F or -20 °C at night—it’s only 15 °F or -10 °C. Five- and ten-inch snow storms have made way for two-inch storms mixed with an inch of rain. And birds that spent the winter down south are migrating back to their breeding grounds up north. Some of them stop over in Michigan for a day or two, where the ice on lakes and rivers is just melting. The opening waters also draw birds that live here year round out of hiding. It made Ann Arbor’s Geddes Pond a rewarding place to visit with my camera yesterday.
