I love the markings of this one.
Black and White Warblers breed in Northern and eastern North America and winter in Florida, Central America and the West Indies down to Peru. They measure between 11 - 13 cm in length and weigh between 8 - 15 grams.
Black and White Warbler measures 2.5 x 3.5 inches and is painted on Colourfix Smooth Paper.
Many thanks to Andy Morffew for the reference photo.
