Early April has brought a steady trickle of new-for-the-year migrants. The female Black and White Warbler arrived today. One or two Prairie Warblers have been marked each time the temperature perks up. The Blue-headed Vireo made its annual visit a bit later than usual. And the House Wren completed our first ever "wren sweep" in a season--Carolina, Marsh, Sedge and House!
