Nashville Warblers are found in North and Central America. They measure between 10 -12 cm in length and weigh between 7 - 12 grams. An interesting fact about them is that they sometimes use porcupine quills as nest material.
Nashville Warbler No 2 measures 3.5 x 2.5 inches and is painted on 300 gsm smooth Arches watercolour paper.
