The first White-crowned Sparrow, last year, showed up on May 1. It is 3 days earlier than that this year, despite the cold, wet April we have had. So the White-throated was later by three days, and the White-crowned was earlier by three days. There's no second-guessing Mother Nature. She will always prevail.
