Usually the American Robins will start showing up in force. Now you will see them occasionally throughout the winter as they are year-round residents here. But usually in March they start showing up in large numbers feeding on the worms and bugs emerging from your yard. Males and females look quite a bit alike, but females tend to be more gray and dull colored such as this female in the photo above is.
Of couse this then brings out all the insects! As a lover of macro photography, this is a good thing. So I am hoping for a continued warm up to kick spring into high gear. It also triggers the instincits in me to get out and start searching for new subjects to photograph.
