This little songbird is found in eastern and southern United States. They are about 11 - 13 cm in length. An interesting fact is that they bath by rubbing themselves again wet foliage.
White Eyed Vireo measures 3.5 x 2.5 inches and is painted on 300 gsm smooth Arches watercolour paper.
Many thanks to Andy Reago and Chrissy McClarren for the reference photo.
