Spring colors

A colorful assemblage of migrants at work this morning, including brilliant blue male Indigo Bunting and everyone's favorite orange and black Baltimore Oriole. Not much singing in the woods, Warbling Vireo, Northern Parula. A male Eastern Bluebird was defending a nest box from four dive-bombing Tree Swallows in the field by the barn. Common Yellowthroats were singing in the brush below the power lines. (photo: National Park Service)
