Each mid-April through May, Maine birders await the annual stream of vibrantly colored spring warblers. The timing and pace of warbler migration, spread across the span of six weeks or so, varies slightly from year to year, depending on ambient weather factors. The overall patterns of movement hold true, however. Spring migration follows a condensed and rapid schedule, as birds sense an urgency to claim nesting territories and get down to business. ~ Don Reimer
